A summary of the performance of exposure rate and dose rate instruments contained in Instrument Evaluation Reports NRPB-IE1 to NRPB-IE13

A concise summary is given of the more important performance characteristics of eleven types of radiation protection dose rate and exposure rate survey instruments which have been assessed by NRPB as part of the instrument evaluation programme and published in the NRPB-IE report series. Characteristics considered are: dynamic range of exposure rate, overload performance, response as a function of photon energy, response to β radiation, response as a function of ambient temperature, battery life and the variation of indication during that life, response to pulsed sources of radiation, cost and availability of instruments.
