What is the name of the agency responsible for radiation safety regulation in Canada?

The agency responsible for radiation safety regulation in Canada is the Canadian Nuclear Safety Commission (CNSC). The CNSC is mandated to regulate the use of nuclear energy and materials to protect the health and safety of Canadians and the environment. It oversees the nuclear industry by issuing licenses, conducting inspections, and ensuring compliance with safety regulations. This agency's role is crucial as it establishes standards and guidelines for radiation safety, which are essential for preventing hazards associated with radiation exposure.

The other choices refer to organizations that do not specifically handle radiation safety regulation in the context of nuclear energy and materials. The Atomic Energy Control Board, for instance, was a predecessor to the CNSC but is no longer in operation. Similarly, the Canadian Centre for Occupational Health and Safety focuses on workplace health and safety across various industries and not exclusively on radiation. The Radiation Safety Board is not an official regulatory agency recognized in Canada and does not hold the same authority as the CNSC. Thus, the CNSC is the appropriate regulatory body for ensuring radiation safety in Canada.
