Health Studies

The Canadian Nuclear Safety Commission (CNSC) continuously conducts and reviews health studies on a variety of areas associated with the production, possession or use of nuclear substances. The information gathered in these studies serves to guide the CNSC in decisions affecting its regulatory framework.

Part of the CNSC's mandate is to provide objective scientific, technical and regulatory information to the public on nuclear-related health and safety topics. The following are highlights of that work.

Hot Topics

CNSC staff constantly review literature from peer-reviewed journals as well as pertinent non-peer-reviewed literature to ensure that the most up-to-date information is used to support our regulatory framework. Comments and interpretations are provided here for selected topics.

Useful Tools

To assist readers in their understanding of our technical reports, the CNSC has put together a group of useful resources. These lay the foundation for understanding the different kinds of studies and highlight important factors to consider when reviewing a study. They provide details on the basics of topics like radiation, epidemiology and explain related terminology.

Health Studies

CNSC staff conduct health studies on various topics, including tritium, uranium mining and milling, other mining activities, nuclear energy workers and members of the general population. These studies are conducted in order to enable the effective management of radiation risks and to set regulatory limits that will protect workers and the public from ionizing radiation.
