Abstract: MCNP calculations have been performed to investigate the effects of beam divergence on the response of selected cylindrical neutron area survey meters irradiated by selected neutron sources. By comparing the results to calculations performed using plane-parallel beam irradiations, geometry correction factors have been calculated that can be applied to instrument calibrations. The results indicate that the effective centres of cylindrical detectors may not lie on the axis of symmetry, as previously assumed.<br /> (Crown Copyright 2010. Published by Elsevier Ltd.
