International Commission on Radiological Protection
At the second congress, held in 1928 in Stockholm, three international commissions were set up - the International Commission on Radiological Protection (ICRP), the International Commission on Radiation Units and Measurements (ICRU) and the International Commission on Radiological Education (ICRE). The former two have become fully functional organisations in their own right while the latter has remained a sub-committee of the ICR.
