Radiation protection

Radiation protection is the science and practice of protecting people and the environment from the harmful effects of ionizing radiation. The CNSC’s radiation protection safety and control area (SCA) covers the requirement for our licensees to implement radiation protection programs that ensure contamination levels and radiation doses to workers and members of the public are monitored, controlled and kept below regulatory limits and as low as reasonably achievable (ALARA).

Radiation protection principles are based on sound science arising from fields of research such as radiation and health sciences (UNSCEAR: United Nations Scientific Committee on the Effects of Atomic Radiation) and the applied integration of this science within a recognized framework for protection of workers and the public (ICRP: International Commission of Radiological Protections and IAEA: International Atomic Energy agency).

In this category you will find research and technical information about radiation, radiation health effects, and radiation protection. Information related to the protection of the public may be co-located under the environmental protection web page as public exposure is primarily through off-site environmental pathways.
