The International Commission on Radiological Protection (ICRP) is an advisory body providing recommendations and guidance on radiation protection; It was founded in 1928 by the International Society of Radiology (ISR) and was then called the ‘International X-ray and Radium Protection Committee’. Then it was restructured to better take account of uses of radiation outside the medical area, and given its present name, in 1950. ICRP is a not-for-profit organisation in the United Kingdom and currently has its scientific secretariat in Ottawa, Canada.
The ICRP defined the reference man in 1974.
