Information System on Occupational Exposure (ISOE)


ISOE provides a forum for radiation protection professionals from nuclear electricity utilities and national regulatory authorities worldwide to share dose reduction information and operational experience to improve the optimisation of worker radiological protection at nuclear power plants.  ISOE provides its members with:


ISOE was launched in 1992 by the OECD Nuclear Energy Agency (NEA) to improve the management of occupational exposures at nuclear power plants through the collection and analysis of occupational exposure data and trends, and through the exchange of lessons learned among utility and national regulatory authority experts. Since 1993, the International Atomic Energy Agency (IAEA) has co-sponsored the ISOE programme, thus allowing the participation of utilities and authorities from non-NEA member countries.

Membership and organisation

ISOE participation includes nuclear electricity utilities and national regulatory authorities which participate under the ISOE Terms and Conditions. Official participants include (as of June 2015):

ISOE operates in a decentralised manner. A management board of representatives from all participants, 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. National co-ordinators in each country serve as contact points for the transfer of information from and to participants.

ISOE is jointly sponsored by the NEA and IAEA.

Main activities

Built on a global network of radiation protection professionals from nuclear electricity utilities and national regulatory authorities, ISOE provides the world's most comprehensive source of experience, information and data for occupational exposure management at nuclear power plants. ISOE provides an operational experience base for identification and assessment of good practices and facilitates the input of operational experience into the development of radiological protection recommendations, standards, etc.

ISOE facilitates global cooperation between utilities, the sharing of experience and the building of linkages between ISOE regions to develop a global approach to ALARA exposure management.  ISOE offers its members a variety of relevant resources, including:
