The “International Commission on Radiological Protection”, was founded under the name “International X-ray and Radium Protection Committee” upon the resolution of the 2nd International Congress for Radiology in 1928. In 1950 the commission was restructured and renamed. It co-operates closely with the International Commission for Radiological units and measurements (ICRU) and has official links to the World Health Organisation (WHO), to the International Labour Organisation (ILO) and other corporations of the United Nations, including the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and the United Nations Environment Programme (UNEP) as well as the Commission of the European Communities, the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (NEA), the International Standard Organisation (ISO), the International Electrotechnical Commission (IEC) and the International Radiation Protection Association (IRPA). The International Commission on Radiological Protection consists of a chairman, twelve further members and a secretary. The members are voted based on nominations by the ICRP submitted by the national delegations of the International Congress for Radiology and by its own members. The ICRP members are selected on the basis of their recognized performances in medical radiology, radiation protection, physics, medical physics, biology, genetics, biochemistry and biophysics.
