Order issued to Montreal Neurological Institute and Hospital

The Canadian Nuclear Safety Commission (CNSC) has issued an order to Montreal Neurological Institute and Hospital (MNIH) located in Montreal, Quebec. MNIH currently holds a CNSC licence authorizing the production and processing of positron emission tomography (PET) medical isotopes used for medical imaging research.

The order was issued following the licensee’s failure to provide a satisfactory response to a CNSC inspection finding of non-compliance. The inspection revealed that licensee workers perform hand manipulation of high-activity sources and that the licensee has failed to implement practices that would keep worker doses as low as reasonably achievable (ALARA).

The order requires the licensee to prohibit manual manipulation of sources in the shielded hot cells with activities exceeding 11.1 GBq, until the licensee submits adequate processes for minimizing worker doses and justification to allow limited hand manipulation in the hot cells.

The CNSC requires these measures to protect the health and safety of workers, the public and the environment.
