The Information System on Occupational Exposure (ISOE) was created in 1992 to provide a forum for radiological protection professionals from nuclear electricity licensees 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.
ISOE is jointly sponsored by the OECD Nuclear Energy Agency (NEA) and the International Atomic Energy Agency (IAEA).

ISOE Members
Membership in ISOE includes representatives from nuclear electricity licensees and national regulatory authorities.
As of December 2023, there are 77 nuclear licensees in 31 countries, as well as 27 regulatory authorities of 25 countries participating to the system.
ISOE Structure
The ISOE operates in a decentralised manner. Decisions and overall direction are provided by the ISOE Management Board, composed of representatives from nuclear licensees and regulatory authorities from all participating countries. The ISOE Bureau, elected by the Management Board, guides ISOE and Secretariat work between Management Board meetings. Both are supported by the joint NEA/IAEA Secretariat.
Four ISOE Technical centres (Asia, Europe, IAEA and North America) serve the programme’s day-to-day technical operations and are contact points for the transfer of information from and to participant countries.
A National co-ordinator in each country provides a link between ISOE participants and the ISOE programme.
Specialised working groups, mandated by the Management Board, are created on an as-needed basis to support the goals of the ISOE on specific topics.
