National Dose Registry
The National Dose Registry (NDR) contains the dose records of people 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.
Functions of the NDR:
- Assistance in regulatory control by notifying regulatory authorities of overexposures within their jurisdiction.
- Evaluation of dose trends and statistics to answer requests from regulators and others, to assist in health research, and to compile into annual reports (posted on the NDR site).
- Providing dose data in combination with production data on behalf of Canada to the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), which compiles such data from participating countries.
- Health research, including epidemiological studies, contributing to the scientific knowledge on risks from occupational exposure to ionizing radiation.
- Providing dose histories to individual workers and organizations for work planning and for compensation and litigation cases.
All outgoing information, including dose histories, may be subject to requirements to ensure confidentiality.
