This report series contains publications of substantial scientific work carried out by the Health Protection Agency (HPA) Radiation Protection Division. It is a continuation of the NRPB-W series reports published by the National Radiological Protection Board (NRPB) prior to its merger with the HPA. HPA became part of Public Health England on 1 April 2013.
The full HPA-RPD series is available on the National Archives. Those reports superseded since publication by the HPA are not reproduced here.
