Full Membership List

ICRP consists of eminent scientists, policy makers, practitioners, and other experts in the field of radiological protection. All members of the Main Commission, Committees, and Task Groups are volunteers, most whose employers pay for their time and travel expenses to work with ICRP. Some volunteer their time outside of regular work or after retirement. Members are invited to serve with ICRP based on the skills and knowledge they bring to the work, and as such do not represent their countries or employers when working with ICRP.
