The Information System on Occupational Exposure (ISOE) was created in 1992 to provide a forum for radiological protection professionals from nuclear electricity utilities and national regulatory authorities worldwide to discuss, promote and co‑ordinate international co-operative undertakings for the radiological protection of workers at nuclear power plants.
The objective of the ISOE is to improve the management of occupational exposure at nuclear power plants by exchanging broad and regularly updated information, data and experience on methods to optimise occupational radiological protection.

Membership in ISOE includes representatives from nuclear electricity utilities and national regulatory authorities.
As of January 2017, there are 77 utilities in 29 countries, as well as 28 regulatory authorities of 26 countries participating to the system.
The ISOE database itself includes occupational exposure information for about 400 operating units and 80 shutdown units or in some stage of decommissioning in 29 countries, covering about 90% of the world’s operating commercial power reactors.
ISOE is jointly sponsored by the:
- OECD Nuclear Energy Agency (NEA), and
- International Atomic Energy Agency (IAEA).
ISOE operates in a decentralised manner. A Management Board of representatives from all participating countries, supported by the joint NEA and IAEA Secretariat, provides overall direction.
Four ISOE Technical Centres (Europe, North America, Asia and IAEA) manage the programme’s day-to-day technical operations, serving as contact point for the transfer of information from and to participants.
