abstract：:The method presented provides an alternative to the shadow shield method for experimentally measuring the contribution due to scattering radiation in a calibration range. Scattering of 0.6616 MeV photons from a Cs irradiator in a calibration range does not only occur due to the walls and floor of the range. It also oc...
