Radionuclides are elements that release energy called radiation. Radionuclides originate from both natural (e.g. soil and rock) and artificial (e.g. certain industrial, military and medical applications) sources (https://www.canada.ca/en/health-canada/services/health-risks-safety/radiation/types-sources/environmental.html).

2019-20 Fees Report of the Canadian Nuclear Safety Commission

This is the 2018 to 2019 Fees Report for the Canadian Nuclear Safety Commission

The Canadian Nuclear Safety Commission (CNSC), formerly the Atomic Energy Control Board (AECB), has legislative control of nuclear fuel cycle materials and man-made radionuclides. However, naturally occurring radioactive material (NORM) is exempt from CNSC jurisdiction except for the import, export and transport of the material. Therefore, jurisdiction over use and radiation exposure to NORM rests with each Canadian province and territory.

The Canadian Nuclear Safety Commission (CNSC) implemented its Independent Environmental Monitoring Program (IEMP) to verify that the public and environment around CNSC-regulated nuclear facilities are not adversely affected by releases to the environment. This verification is achieved through independent sampling and analysis by the CNSC.

Information regarding the uncontrolled release of chemicals, biological agents or radioactive contamination into the environment or explosions that cause widespread damage; and Health Canada's role in preparation for, or in the event of such an emergency.

The following tables contain data on administrative monetary penalties (AMPs) issued by the Canadian Nuclear Safety Commission (CNSC) as part of compliance actions, as permitted under the Nuclear Safety and Control Act. In the current tables, which contains details on companies and individuals, data more than two years old is removed as per CNSC policy in conjunction with the annual update to the CSNC’s Regulatory actions Web page (https://www.cnsc-ccsn.gc.ca/eng/acts-and-regulations/regulatory-action/index.cfm). The historical dataset does not contain this identifying information, and serves to illustrate trends in penalties issued over the longer term.

"This dataset provides the results obtained by two radiation monitoring networks operated by Health Canada: the Canadian monitoring sites of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) and the Canadian Radiological Monitoring Network (CRMN). More information about the CTBT and its monitoring network is available here: http://www.hc-sc.gc.ca/ewh-semt/contaminants/radiation/nuclea/index-eng.php and http://www.ctbto.org/. Further information on the CRMN network is available at: http://www.hc-sc.gc.ca/ewh-semt/contaminants/radiation/crmn-rcsr/index-eng.php. The results provided are activity concentration and uncertainty for various nuclides in the months following the Fukushima Daiichi nuclear accident.

This dataset provides the results obtained by Health Canada’s Radiological Monitoring Network (CRMN) for airborne radioactivity content at monitoring stations across Canada. More information about the CRMN network can be found here: http://www.hc-sc.gc.ca/ewh-semt/contaminants/radiation/crmn-rcsr/index-eng.php. The results provided are activity concentration, uncertainty and the minimum detectable concentration for the naturally occurring radionuclides, beryllium-7 (7Be) and lead-210 (210Pb), and the anthropogenic (originating from human activity) radionuclides, cesium-134 (134Cs), cesium-137 (137Cs), and iodine-131 (131I). The data comes from the analysis of particulates accumulated in filter media, drawn by high-volume air samplers fixed in the field.

Since the Fukushima-Daiichi nuclear accident, the Radiation Protection Bureau (RPB) of Health Canada has performed several analyses of the radioactive content of fish samples from Canada’s west coast. RPB is making the results of these measurements available in three separate, publicly accessible files. The first series of measurements (Radioactivity in Fish- 2011-2012 -Data) was done in collaboration with the Canadian Food Inspection Agency (CFIA) at the onset of the emergency in Japan. The next set of measurements (Radioactivity in Fish- 2013 -Data) was done in collaboration with Fisheries and Oceans Canada as part of a research and development project that led to a peer reviewed publication (A Report on Radioactivity Measurements of Fish Samples from the West Coast of Canada, Radiation protection dosimetry, 2014, http://rpd.oxfordjournals.org/content/early/2014/05/01/rpd.ncu150.full).
