The National Radiological Protection Board (NRPB) was a public authority in the UK created by the Radiological Protection Act 1970. Its statutory functions were to conduct research on radiological protection and provide advice and information on the subject to Government Departments and others. It was also authorized to provide technical services and charge for them. Originally NRPB dealt only with ionizing radiation, but its functions were extended in 1974 to non-ionizing radiation.
