The National Dose Registry (NDR) contains the dose records of individuals who are monitored for occupational exposures to ionizing radiation. The NDR started collecting data from 1951 and now has records for over half a million workers, including well over 100,000 who are currently monitored. It now contains monitoring records back to the 1940's.
Occupational exposures to X-rays are within the jurisdiction of provincial governments in most cases. For more information on X-ray regulations, please contact your province or territory.
Exposures to radiation from nuclear reactions and radioactive decay are within the jurisdiction of the Canadian Nuclear Safety Commission (CNSC).
All information provided by the NDR, including dose histories, may be subject to confidentiality requirements.
