Abstract

The aim of this work was to provide information which could be used to improve the efficiency and cost effectiveness with which regular calibrations and checks of area survey instruments and personal dosemeters are carried out. To this end the variation in functional scatter component with distance from the neutron source has been determined using calculations, spectrometry and by reviewing the results of calibrations carried out since 1989, together with studies performed at NPL in 1982 and 1988. Scatter fraction relationships have been produced for 241Am-Be and 252 Cf sources, in terms of neutron fluence, ambient dose equivalent and instrument responses.
