Regulatory document RD/GD-338, Security Measures for Sealed Sources sets out the minimum physical security measures that licensees must implement to prevent the loss, sabotage, illegal use, illegal possession, or illegal removal of sealed sources in storage at the site of a licensed activity. This includes measures to prevent the loss, sabotage, illegal use, illegal possession, or illegal removal of sealed sources while they are in transport or being stored during transportation.
This document also provides information and guidance on how to meet the minimum physical security measures, including measures related to transport vehicles, containers and security plans. This document applies to transport by road within Canada only (there are other instruments and technical instructions that regulate the safe transport of dangerous goods by sea, air and rail).
In September 2003, the International Atomic Energy Agency (IAEA) approved the Code of Conduct on the Safety and Security of Radioactive Sources. Canada, along with many other countries, has undertaken to abide by this Code and work toward its full implementation. RD/GD-338, Security Measures for Sealed Sources supports the regulatory framework to enforce international guidelines set by the IAEA, and provides consistency in the application of security measures.
Most carriers are not licensed by the Canadian Nuclear Safety Commission (CNSC) and are not subject to the security requirements applicable to CNSC licensees when transporting or storing sealed sources while in transit. This document is intended to assist licensees with contracting carriers, so as to ensure that specific physical security measures are taken into consideration when transporting sealed sources, during storage or while in transit.
RD/GD-338, Security Measures for Sealed Sources reflects the security goals of United Nations specialized agencies and programs – including the International Maritime Organization (IMO), the International Civil Aviation Organization (ICAO) and other intergovernmental organizations such as the International Carriage by Rail – as they have taken similar steps to provide improved security in the transport of dangerous goods carried by sea, air and rail. These organizations have developed various instruments, such as the International Maritime Dangerous Goods Code, and technical instructions for the safe transport of dangerous goods by air.
This document applies to sealed radioactive sources (encapsulated or solid) and does not apply to unsealed radioactive substances. This document applies to Category 1, 2, and 3 sources and provides “best practices” for Category 4 and 5 sources. In this document, the terms Category 1 to 5 sources are used as defined in the IAEA’s Code of Conduct on the Safety and Security of Radioactive Sources or IAEA/TECDOC-1344, Categorization of Radioactive Sources.
Nothing contained in this document is to be construed as relieving any licensee from pertinent requirements. It is the licensee’s responsibility to identify and comply with all applicable regulations and licence conditions.

Radioactive sealed sources and prescribed equipment containing nuclear substances are regulated under the Nuclear Safety and Control Act (NSCA) and the regulations made under the NSCA, such as the General Nuclear Safety and Control Regulations, Class II Nuclear Facilities and Prescribed Equipment Regulation, Nuclear Substances and Radiation Devices Regulations and the Radiation Protection Regulations.
Additional regulations related to the transport of sources (such as packaging, documentation and safety markings) include:
- Canadian Nuclear Safety Commission (CNSC), Packaging and Transport of Nuclear Substances Regulations
- Transport Canada, Transportation of Dangerous Goods Regulations
This document uses a graded approach for the security of sealed sources. There are five levels of sealed sources (Categories 1 through 5). This document applies to radioactive sealed sources that may pose a significant risk to the environment and the health and safety of persons (i.e., Category 1, 2 and 3 sources). Because Categories 4 and 5 are least dangerous, this document provides prudent management practices for those categories.
This regulatory document applies to sealed sources of nuclear substances identified in Table A. These substances and threshold values are based on the IAEA Code of Conduct on the Safety and Security of Radioactive Sources . The main objective of this regulatory document is specific to radioactive sources that could be dangerous to the health and safety of persons and to the environment if they are not protected (that is, Category 1, 2 and 3 sources).
As outlined in IAEA TECDOC-1344 , if a practice involves the accumulation of several sources into a single storage or use location, where these sources are in close proximity (such as in storage facilities, manufacturing processes, or transport conveyance), the total activity is treated as a single source for the purpose of assigning a category.
The security requirements must be commensurate with the categorization, threat level and/or level of risk set by the licensee or the Government of CanadNote that mobile and portable radioactive sources may need to be treated differently, to ensure that any specific security requirements are fulfilled, thereby allowing the source to be used as intended.
The CNSC bases its categorization of sources on the IAEA source categorization as defined in IAEA/TECDOC-1344 . This document recognizes that not all radioactive sources could (or should) be treated alike, and has established five source categories, ranging from Category 1 (extremely dangerous) to Category 5 (unlikely to be dangerous). The IAEA categorization methodology has found worldwide acceptance, and provides a uniform means of classifying the risk associated with the most commonly used radioactive sealed sources and radiation devices.
Sealed sources and radiation devices may be used in one location (for example, fixed gauges used on process equipment) or they may be mobile and used on different job sites (for example, radiography exposure devices and portable soil moisture density gauges).
Category 1 sources are the most dangerous sealed sources licensed by the CNSC. Because they pose the greatest risk to the health and safety of persons and to the environment, Category 1 sources are always used in a well-shielded and well-controlled location. Examples include cobalt-60 teletherapy sources used for cancer treatment and cobalt-60 sources used in pool-type irradiators to sterilize medical products. Such sources should be shielded and secured safely.
The most common example of a Category 2 source is an industrial radiography exposure devicThese devices are portable, and are widely used in pipeline work and in pressure vessel fabrication shops (particularly in the oil and gas industry).
More numerous are the fixed and portable radioactive gauges in Category 3 and Category Category 3 sources are often fixed gauges that are bolted to pipes, vessels and assembly lines where they operate reliably in harsh industrial environments, often for decades. Category 4 sources include the portable soil-moisture density gauges that are used in road construction.
Category 5 sources are low-risk. Examples include electron capture detectors used to measure pesticide residues in food, x-ray fluorescence analyzers, and low-dose brachytherapy implant sources. Some Category 5 sources may be used without a CNSC-issued licence.
Table A provides thresholds of Category 1, 2 and 3 sources, measured in activity level.
|Nuclear substance||Category 1 source||Category 2 source||Category 3 source|
|Americium-241) / Beryllium (241Am/Be)||60||1,600||0.6||16||0.06||1.6|
|Plutonium-239 / Beryllium (239Pu/Be)||60||1,600||0.6||16||0.06||1.6|
|Strontium-90 (90Sr) (Yttrium-90 (90Y))||1,000||27,000||10||270||1||27|
The materials and thresholds in Table A are based on the IAEA Code of Conduct on the Safety and Security of Radioactive Sources . These thresholds aim to provide consistency between domestic and international requirements for the protection of radioactive material.
There are 16 nuclear substances that could pose a serious threat to the health and safety of people and to the environment. Irradiated fuel and mixed oxide fuel are not included in the list even though they contain quantities of radioactive material; these materials are covered by the Nuclear Security Regulations.
Terabecquerel (TBq) is the official measurement unit used for determining whether a radioactive material is a Category 1, 2, or 3 sourcBecause many licensees use Curies in their activities instead of Becquerels, the table also provides the equivalent Curie (Ci) measurement for practical usefulness.
IAEA RS-G-1.9, Categorization of Radioactive Sources  provides the methodology for the development of the Code of Conduct thresholds.
These regulatory requirements apply only to sealed sources. However, it is recommended that comparable security requirements be taken into account for open or unsealed sources when considering the suitability and adequacy of the storage arrangements.
To assign a category, the total activity of all sources in one facility (storage or use) where sources are in close proximity must be equal to, or greater than, the number identified in the category. For example:
- a teletherapy medical device with a sealed source up to 555 TBq of cobalt-60 is a Category 1 source (555 > 30)
- a certified radiography exposure device with a sealed source of 2.5 TBq of iridium-192 is a Category 2 sealed source (80 > 2.5 > 0.8)
- a high dose rate (HDR) brachytherapy medical device with a sealed source up to 0.44 TBq of iridium-192 is a Category 3 source (0.8 > 0.44 > 0.08)
For security control purposes, the aggregation of sources in a single storage (or use) facility can be used to determine a situation-specific sealed source category. This is done by adding the actual sealed source activities of the sources and determining the category from Table A. For example, one industrial level gauge containing a sealed source with 0.19 TBq of cesium-137 is a Category 3 source (1.0 > 0.19 > 0.1). However, when there are six of these sealed sources at a single licensed location, they can be treated as a Category 2 source (6 x 0.19 = 1.1 > 1.0).
While in storage, licensees shall develop and implement technical and administrative security measures to protect the radioactive source against unauthorized removal (such as theft or loss) or sabotage.
As outlined in IAEA TECDOC-1355 , these measures shall integrate safety and security concepts involving industrial safety arrangements, radiation protection measures and appropriate design to achieve the necessary level of protection against unauthorized removal of radioactive sources.
The licensee should develop and maintain a threat and risk assessment to determine vulnerabilities in the existing physical protection systems designed to protect against the loss, sabotage, illegal use, illegal possession, or illegal removal during the storage or transportation of the sealed sourcThe threat and risk assessment, updated annually, is also used to determine mitigating security measures to address identified threats, manage risks or reduce/eliminate vulnerabilities.
Table B provides information on how security program subsections should be applied to Category 1 (high risk), Category 2 (high risk), Category 3 (medium risk), and Categories 4 and 5 (low risk).
|Security program sub sections||Category 1- high risk||Category 2- high risk||Category 3- medium risk||Category 4 and 5- low risk|
|Facility security plan||
|Perimeter and physical barrier (1st line of defense)||
|Security of storage (2nd line of defense)||
|Intrusion detection system||
|Transportation security plan||
|Personal trustworthiness or background checks||
|Maintenance and testing||
|Security awareness program||
Technical security measures for radioactive sources, devices or facilities shall include physical measures to:
- prevent unauthorized personnel from gaining access to such sources
- protect against an act or attempted act of unauthorized removal
- protect against an act or attempted act of sabotage
Technical security measures shall also include hardware and/or security systems designed according to the principle of defence in depth and the physical protection system functions of “detection, delay and response”.
This section includes security requirements for the following measures:
- access control
- detection of unauthorized access
- locking hardware and key control
- physical barriers (secure containers, secure enclosures)
- alarm response protocols
- inspection, maintenance and testing of physical security-related equipment
- security officers
Within each of the areas identified above, the licensee shall define appropriate security measures that are commensurate with the level of risk presented by the sealed source(s). Further details are provided in sections 3.2.2 to 3.2.8.
In support of paragraphs 3(1)(g) and 3(1)(h) of the General Nuclear Safety and Control Regulations, the licensee shall include in their licence application details pertaining to physical security measures for access control, physical barriers, detection of unauthorized access, maintenance and testing of physical security-related equipment.
184.108.40.206 Requirements for access control
The licensee shall implement access control measures (e.g., access card readers, personnel identification systems, manual or electronic locks) or use security officers to ensure that only authorized persons have access to storage areas containing sealed sources at all times.
Visitors, building maintenance staff, servicing companies and contractors who require access to the sealed source storage shall be escorted at all times if they do not possess a trustworthiness verification approved by the licensee.
220.127.116.11 Guidance for access control
To control access to the sealed sources, the licensee should:
- prevent unauthorized access to the sources
- monitor and maintain records of all personnel with access to secure storage areas, through the use of a log book or an access control system with tracking capabilities
- implement effective access control measures, such as manually activated locking devices, padlocks, card reader access and biometric devices/systems, and through the use of “controlled” entry points
- ensure the access control system incorporates measures to prevent unacceptable practices such as “pass back” or “tailgating”
- assign individual personal identification number (PIN) codes if used in conjunction with an access control system
- remove access rights for individuals as soon as access is no longer required
- restrict access rights to the access control management system and software, to prevent unauthorized interference with the system database (hacking, software sabotage)
- implement a means of duress signalling near the source storage, to provide notice to the alarm monitoring company or response personnel
- implement a local alarm that triggers in the vicinity of the storage area, to alert nearby personnel of an intrusion or other problem in the source storage area
The security program should include security measures relating to detection, delay and response to security events (e.g., alarm detection devices, fencing, secured storage containers, immobilization of vehicles and/or trailers, security officers).
18.104.22.168 Requirements for detection of unauthorized access
The licensee shall implement measures for the detection of attempted or actual unauthorized access in a timely manner, such as:
- visual observation
- video alarm assessment
- detection devices
- accountancy records, seals, or other tamper-indicating devices including process monitoring systems (for example, daily or twice-weekly audits, to ensure that the sources are present)
Note that, for mobile sources in use, continuous visual surveillance by operator personnel equipped with an appropriate communication link may substitute for one or both layers of barriers.
If an intrusion detection system is used, it must:
- immediately detect any unauthorized intrusion into the sealed source storage area
- immediately detect any tampering that may cause any of the alarm system devices to malfunction or cease to function
- when an intrusion is detected, set off a continuous alarm signal that is both audible and visible at the licensee’s location and/or at an approved monitoring station, using a supervised communications link; the monitoring station shall be certified by a body accredited by the Standards Council of Canada, or other certification body deemed acceptable by the CNSC staff
- include an uninterruptible power supply subject to routine testing, to ensure continuous operability of the security detection system
22.214.171.124 Guidance for detection of unauthorized access
To detect unauthorized access, the alarm system should:
- activate immediately upon detecting an intrusion or tamper event
- stay in an alarmed state until acknowledged by an authorized person
- have two or more zones for each area of storage
- have an acceptably low nuisance and/or false alarm rate
- be certified by the Underwriters Laboratories (UL) or Underwriters Laboratories of Canada (ULC)
The licensee should:
- ensure that alarm monitoring devices and back-up battery power are protected against tampering by unauthorized personnel (e.g., electronic panel or junction box)
- ensure the keypad is installed within a secure environment, to prevent tampering
- use dedicated alarm zones in the storage area (separate from any other alarm zones) and limit access to authorized users only
- maintain an audit trail to record the cause of any alarms
For example, consider a radiography company that has a warehouse equipped with an alarm system. Two zones are set up: one zone for the warehouse and a second interior zone for the storage areDuring the day, the main alarm system for the warehouse is deactivated but the security system for the storage area remains activated and operates independently of the main system.
126.96.36.199 Requirements for locking hardware and key control
Access cards, door keys, or locks that control access to storage areas shall be restricted to personnel authorized by the licensee.
The licensee shall maintain records of all access control authorizations, including locking devices (either electronic or manual). Such records shall include the names of the individuals to whom the locking devices or combinations have been issued, and the date of issuance.
The licensee shall develop and maintain written procedures that include measures for repairing or replacing a locking device, key, access card or combination that is defective, lost, stolen, or unlawfully transferred, or has otherwise become compromised.
188.8.131.52 Guidance for locking hardware and key control
The licensee should develop, maintain and adhere to written procedures for issuing, repairing or replacing a securing device, key, access card or combination that is defective, lost, stolen or otherwise compromised.
If keys are used, the licensee should implement a key control policy to:
- restrict the number of individuals with keys
- restrict the number of master keys
- prohibit employees from duplicating keys
- use a patented key or dedicated keyway to prevent unauthorized duplication of keys
- include a provision for employees to return keys when access is no longer required
- ensure that key blanks are stored securely
For key control, the licensee should:
- conduct a review of the key inventory and keyholders on a regular basis
- note changes and additions to the key inventory and keyholders in their records
- maintain accountability for all keys that have been issued and keys reported lost or stolen
Locks with combination codes or cipher-based keyless locks are not recommended.
When conventional locks and keys are used, they should be of good quality. Key management procedures should be designed to prevent unauthorized access or compromisThe locks should have shielded shackles, to prevent cutting of the lock.
184.108.40.206 Requirements for physical barriers
For sealed sources whose activity is less than the threshold levels listed for Category 3 in Table A, the licensee shall store the sources in secure containers, as described in section 220.127.116.11.1.
For sealed sources whose activity is equal to or above the threshold levels listed for Categories 1, 2, or 3 in Table A, the licensee shall implement a minimum of two different physical barriers, to prevent unauthorized access to sealed sources in storage or provide delay sufficient to enable response personnel to intervene as required.
The physical barriers shall be any combination of secure containers or other secure enclosures. For example:
- a licensee who stores a sealed source in a locked safe may locate the safe in an enclosed room that can be locked, and must secure the container in place (floor, wall or vehicle)
- alternatively, the safe may be located within a locked metal cage or other suitable enclosure
- the access-controlled perimeter of the licensee’s location may serve as the first secure enclosure, with a secondary secure enclosure or secure container inside, both with access control
Note that for a mobile source in use, it may not always be possible to achieve the security measures specified abovIn such cases, compensatory measures shall be implemented to provide other forms of protection (e.g., close supervision combined with an appropriate communication link).
18.104.22.168.1 Requirements for secure containers
Secure containers include items such as filing cabinets, metal boxes, safes, and wire mesh cages. For a container to be considered secure, it must be:
- securely affixed in place
- resistant to physical attack using handheld tools
- fitted with a key or combination padlock, or similar lock, that can resist surreptitious or forced attack using handheld tools
- when a wire mesh cage is used, the cage fabric must be expandable metal mesh no smaller than number 10 gauge 
22.214.171.124.2 Requirements for secure enclosures
Enclosures include rooms, buildings or cages that can be secureFor an enclosure to be considered secure, all exterior components (e.g., walls, doors and windows) are resistant to physical attack using handheld tools and access/egress points are equipped with access control devices, or access is controlled by security officers.
Windows that provide access to interior areas in proximity to sources must be equipped with bars (where the gap between the bars must be less than 15 cm), metal grill, expanded metal mesh, and/or retrofitted with a UL/ULC certified security film or glazinSecurity hardware attached to windows must be affixed from the inside to prevent tampering, or fitted with tamper-resistant devices if fitted from the outside.
Doors that provide access to areas where nuclear substances and radiation devices are used, processed or stored must be secured when left unattendeDoors must be solid-core wood or metal clad and installed in a reinforced frame of equivalent material. Doors must be maintained in good state of repair and fitted with non-removable pinned hinges, if the hinges are mounted on the outsidAny door glazing or large vents (grills) must be fitted with security glazing or bars, metal grills, or equivalent. Grills must be secured in place with tamper-resistant devices.
126.96.36.199 Guidance for physical barriers
Traditional barriers such as chain-link fences, locked doors, grilled windows, masonry walls and vaults are commonly used for storage of radioactive sealed sources. Barriers should be considered in relation to an adversary’s objectives.
The licensee should implement multiple physical barriers to protect the radioactive sources. Multiple barriers potentially force an adversary to bring a variety of tools to defeat each individual barrier, thereby delaying the adversary and providing the response personnel with time to intervenOne implementation of the concept of defence in depth is to have multiple layers of different barrier types along the path to complicate an adversary’s progress by requiring a variety of tools and skills (see Figure 1).
Figure 1: Adversary path to a storage area
For example, multiple barriers may include:
- a portable device (e.g., portable gauge, exposure device) stored inside a vault or safe that is bolted to the floor and capable of resisting common attack tools
- a mobile device (e.g., a brachytherapy unit) may be chained to the floor within the storage areThe chain is made of material resistant to common attack tools and is secured with a good quality padlock that has the same level of robustness (e.g., shielded shackles)
- a solid-core door made of wood or metal, installed with non-removable screws, pinned door hinges, a latch protector and an automatic door closer
- a window equipped with laminated window-film resistant to burglar attacks, metal mesh or metal bars spaced at 15 centimetres or less, and installed with non-removable screws
188.8.131.52.1 Guidance for secure containers
The storage location and/or container should:
- be secured with a locking mechanism or have other measures to prevent unauthorized removal
- be secured when left unattended
- be equipped with an alarm system to detect unauthorized entry or access
- be sufficiently robust to resist common attack tools (e.g., sledgehammer, crowbar, drill, blowtorch)
184.108.40.206.2 Guidance for secure enclosures
Openings, such as windows or vent ducts, that could provide access to secure enclosures should be fitted with bars, a metal grill, expanded metal mesh, and/or retrofitted with a UL/ULC certified security film or glazinSecurity hardware attached to windows should be affixed from the inside, to prevent tampering, or be fitted with tamper-resistant anchors if affixed from the outside.
Doors that provide access to areas where radioactive sealed sources and/or radiation devices are used, processed or stored should be secured when unattendeThe material used for the door should be solid-core wood or metal-clad, and the door should be installed in a reinforced frame of equivalent material. Doors should be in a good state of repair. If the hinges are mounted on the non-secure side, the door should be fitted with non-removable pinned hinges. Any door glazing or large vents (grills) should be fitted with security glazing or bars, a metal grill, or equivalent. Grills should be secured in place with tamper-resistant anchors.
If continuous visual surveillance is done by an operator, the operator should be equipped with a means of communication (e.g., cell phone or radio) and should be aware of the response protocols to communicate rapidly to response personnel in the event of unauthorized access or removal.
If key pads are used to arm and disarm an intrusion detection system, the device and its electric junction box should be installed in a secure area, to reduce the risk of tampering.
To maintain continuous power to the alarm monitoring detection system in the event of a loss of primary power, the licensee should consider implementing an alternate or auxiliary power back-up source, or equivalent, to maintain detection capability.
220.127.116.11 Requirements for alarm response protocol
The licensee shall respond immediately to any actual or attempted theft, diversion or sabotage to radioactive material or devices.
The licensee shall develop and maintain a documented alarm response protocol to record the cause and dispensation of alarms. The protocol shall include the role and responsibilities of the licensee’s emergency response staff and offsite response force, and shall be documented in a contingency plan or an equivalent document.
The licensee must notify the local police force of jurisdiction, informing them that sealed sources are onsite, and include an opportunity for onsite familiarization tours. The licensee shall develop and maintain written arrangements with offsite emergency responders, and update those arrangements annually or when changes to the facility design or operations affect the potential vulnerability of the sourcWritten arrangements are not required for temporary job sites.
18.104.22.168 Guidance for alarm response protocol
The licensee should develop and maintain a documented alarm response protocol that includes:
- response procedures in case of theft, loss or sabotage of a radioactive sealed source
- the role and responsibilities of the licensee’s staff
- communication arrangements with local law enforcement and applicable authorities
- incident reporting/notification
- immediate reporting of any recovered source(s)
To facilitate arrangements with local or provincial law enforcement agencies, or mutual aid agreements with other sites, the licensee should consider written support arrangements such as a memorandum of understanding (MOU). This written arrangement should detail the interaction between site guards or onsite personnel with the agencies.
22.214.171.124 Requirements for inspection, maintenance and testing of security-related equipment
The licensee shall develop and implement written procedures for the testing of physical security equipment and a schedule for routine testing and maintenance in accordance with the manufacturer’s specifications. At a minimum, testing of security equipment including intrusion detection devices shall be conducted every six months. The licensee shall demonstrate that alarm testing was conductePreventive maintenance procedures shall include measures to replace defective equipment and devices in a timely manner.
126.96.36.199 Guidance for inspection, maintenance and testing of security-related equipment
All detection devices should be installed, operated and maintained in accordance with the manufacturers’ specifications and licensee processes. The licensee should test the performance of the detection devices on a regular basis, to ensure reliability and maintain documented records.
Licensees should ensure reliability through a preventive maintenance program that tracks detection device deficiencies. When the device is out of service for repair or replacement, compensatory measures must be implemented.
188.8.131.52 Requirements for security officers
If the licensee uses a security guard service, the licensee shall develop and maintain written procedures and instructions specific to:
- measures for controlling access to the licensed area
- surveillance foot and vehicle patrols
- assessment and response to alarms
- apprehension and detainment of unarmed intruders
- report suspicious activities, including armed intruders, to the police force of jurisdiction
- security equipment operation
- security training relating to assigned duties
184.108.40.206 Guidance for security officers
Security officers should be properly equipped and traineA formal training program should be established that is specific to the security officers. The training program should include:
- requirements of provincial/territorial regulations (if applicable)
- legislation and authorities
- knowledge of the site
- roles, responsibilities and functions
- radiation protection emergency procedures and response protocols
- first-aid training techniques
Security officers should be screened in accordance with the trustworthiness program and should possess a valid licence or certification recognized by the province or territory.
The licensee should consider performing exercises and drills on a regular basis, to validate onsite response force readiness.
For security officers, the licensee should establish and maintain an overall training policy and initial and continuing training programs, based on the long-term qualifications and competencies required for performing the job, and training goals that acknowledge the critical roles of safety and security.
Administrative security measures support technical measures, and shall include the programs, plans, policies, procedures, instructions and practices that the licensee implements to assist in securing licensed radioactive material from unauthorized removal or sabotage.
These measures shall include, but are not limited to, the following:
- site security plan
- security awareness program
- personnel trustworthiness and reliability
- protection of prescribed or sensitive information
- inventory control
- access control procedures
220.127.116.11 Requirements for a site security plan
For Category 1, 2 and 3 sources, technical and administrative measures shall be documented by the licensee in a site security plan, appropriately designated in accordance with section 12(1)(j) and 21 to 23 of the General Nuclear Safety and Control Regulations.

18.104.22.168 Guidance for protection of prescribed and/or sensitive information
“Prescribed information” is defined in the General Nuclear Safety and Control Regulations, section 21 (see glossary).
The following information is considered to be prescribed and should be protected:
- the facility security plan, correspondence related to security, security response measures, contingency plans and transport security plan, if applicable
- the specific location and inventory of sources, installation schematics and security systems including performance testing
- threat and risk assessment and/or vulnerability assessment
Prescribed and/or sensitive information should be:
- protected from unauthorized disclosure and secure when left unattended
- disclosed only to individuals with a “need to know” basis to perform their assigned duties
- stored in a manner that prevents removal or theft
Highly sensitive documents should be stored on a hard medium (diskette, CD-ROM or USB key) or in paper format only, and kept in a secure location that is accessible only to individuals with a “need to know”. This information should not be stored on an open or shared network without proper protection.
For prescribed and/or sensitive information, the licensee should:
- use “portable” storage devices (i.e., computer, external hard drive, USB keys) that can be removed and secured
- use storage devices that are “protected” via passwords or encryption, and are only accessible to authorized users via approved cyber security protocols
- protect the confidentiality, availability and integrity of information or documents containing prescribed information

These inventory checks shall comply with section 36(1)(a) of the Nuclear Substances and Radiation Devices Regulations.
126.96.36.199 Guidance for inventory control
The operator should establish and maintain a list of sealed sources under their responsibility. Inventory verification can be used as part of detection measures. Regular inventory checking should consist of measures to ensure that the sources are present and have not been tampered witSuch measures could include physical checks that the source is in place, or remote observation through closed circuit television (CCTV), or verification of seals or other tamper devices. A process for inventory control should be in place, to ensure a robust verification process.
For the transport of a Category 1 source, the vehicle shall be equipped with:
- a vehicle tracking device that enables the vehicle to be recovered if stolen
- a duress alarm or an equivalent device that is continuously monitored; the licensee shall instruct the alarm monitoring station to alert the appropriate response force (e.g., police agency of jurisdiction)
For Category 1, 2 and 3 sources, the licensee’s vehicles shall be equipped with anti-theft devices. The anti-theft devices shall consist of:
- a vehicle disabling device (e.g., starter disabler that prevents the start of the vehicle without a proper key or a similar start device)
- if the vehicle is left unattended, a device that immediately detects unauthorized entry or attack to the vehicle and triggers an audible or visible alarm. If the vehicle operator is not within hearing or visual range of the alarm, the operator shall have the ability to monitor the alarm devices remotely
These anti-theft devices shall be activated automatically or manually by the operator at any time when the vehicle containing the package is left unattended.
While being stored during transportation, the package shall either be stored in a secure container in the vehicle, or in a location that is protected by physical security measures and is continuously monitored when the package is left unattended.
For Category 4 and 5 sources, the licensee shall implement prudent management practices by using effective access control and ensuring the security of radioactive material and devices at all times.
If a licensee’s transport vehicle is left unattended while transporting Category 1, 2 and 3 sources, the licensee should have a means to immediately detect, assess and respond to actual or attempted theft or diversion of the sealed sources. An alarm system is an acceptable methoExamples of acceptable vehicle disabling devices that provide effective delay include trailer hitch locks, wheel locks (“boots”), or a method to disable the engine.
The licensee should ensure a secondary means to protect the vehicle, including a securing mechanism having a similar attack resistance (e.g., chain, locks, and seals).
As the licensee (the consignor) is responsible for the safety and security of sealed sources during transport, the licensee shall ensure the authorized carrier is capable of providing physical security measures for sealed sources while they are in transport or being stored during transportation.
As required by the Packaging and Transport of Nuclear Substances Regulations, the licensee shall provide the carrier with the appropriate shipping documents relating to the sealed sourcThe shipping documents shall include the corresponding description of security measures for sealed sources. Where more than one category of radionuclide applies (e.g., for shipments of multiple radionuclides) the applicable measures shall be based on the more restrictive category.
All packages containing sealed sources of Category 1, 2 or 3 shall be protected from unauthorized access, theft or unauthorized removal during transport and temporary storage during transport. The consignee should be notified when, where and by whom such packages are being moved, including tracking numbers and expected arrival times. The licensee, being the consignor, shall contract a carrier with a proven record for the safety and security of dangerous goods while in transport, and shall take the following precautions:
- The package containing the sealed source shall be stored in a secure container. Packages over 500 kg are considered secure due to the handling difficulties caused by their weight. The secure container does not replace any other packaging or labelling required by any existing regulations. A secure container:
- shall be made of steel or any other material that is resistant to a physical attack by handheld tools
- shall be equipped with a key, combination padlock or similar locking device that is resistant to an attack using handheld tools
- if transported in an open conveyance (e.g., open back of a half-ton truck, flatbed truck), it shall be securely affixed to the vehicle to prevent unauthorized removal of the container
- if containing a sealed source with an activity level less than Category 3 (see Table A), may be stored in the securely locked trunk or other cargo area of a vehicle while in storage and during transportation
- During a stopover while being transported, the package shall either be stored in a secure container in the vehicle (as described in list item 1, above), or in a location that is protected by physical security measures (as described in section 3).
- The vehicle operator shall have on his or her person, at all times, a reliable mobile communication capability (e.g., cell phone) and a list of contact persons and their contact numbers in the event of an emergency situation.
Alternate methodologies that provide a level of physical security equivalent to that described above may be submitted to the CNSC for review, or identified in a licence application or a request to amend a licence.
For transport of Category 1 or 2 sources and devices, the licensee shall verify that the carrier:
- uses a package tracking system
- implements methods to ensure trustworthiness and reliability of drivers
- maintains constant control and/or surveillance during transit
- has the capability for immediate communication to summon appropriate response or assistance
For transport of Category 3 sources, the licensee shall verify that the carrier:
- implements methods to ensure trustworthiness and reliability of drivers
- maintains constant control and/or surveillance during transit
- has the capability for immediate communication to summon appropriate response or assistance
For transport of Category 4 and 5 sources, the licensee shall implement prudent management practices by using effective access control and ensuring the security of radioactive material and devices at all times.
The licensee should:
- provide security awareness training to all individuals engaged in the handling or transport of sealed sources, including refresher training when required
- verify that, before transporting Category 1 and 2 sources, all persons employed by the carrier transporting the sealed sources have successfully completed security screening for trustworthiness and reliability
The security awareness training should include the items listed for the transport security plan (see section 4.3) and specific information on:
- the identified threats for the conveyance
- security concerns and actions to be undertaken in the event of a security incident during transport
Security devices on the licensee’s transport vehicles should:
- be inspected by the licensee regularly for any signs of tampering or deterioration that may adversely affect their designated function
- be tested by the licensee at least every six months
- be inspected by a qualified operator to ensure integrity of the security mechanism on the vehicle used to transport Category 1 or 2 sources
For sources in use or in transit, such measures may include a secured or fixed container, or placement of the source container inside a secured storage area (e.g., container chained or bolted to the vehicle). For mobile sources in use, continuous visual surveillance may be a substitute for one or two physical barriers. If a sealed source is temporarily stored while in transit (for example, in a warehouse), equivalent security measures should be applied that are consistent with those security measures discussed above for storage of Category 1 and 2 sources.
If packages are transported on an open conveyance, the packages should be shielded and secured to the vehicle for safety and security.
In addition to the requirements in section 4.2.1, the following requirements apply to Category 1 and 2 sources:
