National Dose Registry

State/National Dose Registry

The typical National Dose Registry (NDR) contains the dose records of individuals who are monitored for occupational exposures to ionizing radiation.

What do I need to know?

Individual monitoring of workers exposed to radiation as a part of their job and recording their radiation doses are important parts of national occupational radiation protection programmes. The IAEA General Safety Requirements on Governmental, Legal and Regulatory Framework for Safety (No. GSR Part 1 (Rev.1)) and Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards (No. GSR Part 3) describe the specific characteristics of such programmes.  GSR Part 3 includes requirements for the retention of workers’ occupational exposure records by the regulatory body or a State registry, or by a relevant employer, registrant, or licensee. 

National Dose Registries enable the optimization of protection and help ensure compliance with the dose limits at the national level. The IAEA General Safety Guide  Occupational Radiation Protection (No. GSG-7) notes that a typical registry contains personal, employment and dosimetric data for all occupationally exposed workers in the country. 

Characteristics of a typical NDR 

Consideration should be given to the establishment of a national dose registry as a central point for the collection and maintenance of dose records. The storage of information at the National Dose Registry should be tailored to allow workers, during and after their working life, to retrieve information on the doses they received while occupationally exposed.

Long term storage of such information in a NDR also serves the following purposes:

  1. It prevents the loss of data on individual doses in the event that the registrant or licensee ceases its activities in the State concerned.
  2. It allows periodic analysis of all data collected on exposures  in order to characterize the situation at the national level with regard to occupational exposure.
