About the report

The Occupational Dose Data for Major Canadian Nuclear Facilities Report provides an overview of occupational radiation doses from 2001 to 2007 at major nuclear facilities licensed by the Canadian Nuclear Safety Commission (CNSC). 

The report details the average and collective effective doses and the distribution of doses among workers in the Canadian nuclear industry employed at the following types of facilities:

  • nuclear power plants
  • uranium mines and mills
  • uranium refineries
  • fuel fabrication facilities
  • research and radioisotope production facilities
  • tritium light source production facilities

Highlights of the 2001–2007 report

Overall, the data demonstrates that the average dose for nuclear energy workers at all facilities in the report are far below the individual annual effective dose limit for nuclear energy workers of 50 milliSieverts (mSv), set out in the Radiation Protection Regulations.

In Canada, the average annual effective dose for all nuclear energy workers at facilities in this report remained comparable from 2001 to 2007. The average annual dose varied from 1.54 to 1.99 mSv, with an overall average of 1.77 mSv over the seven-year period (these doses are based on non-zero average doses).
