The influence of scattering on the total efficiency for point sources in gamma-ray spectrometry.

Abstract:

:The contribution of gamma-ray scattering to the total efficiency for point-source geometries in a gamma spectrometer was measured. Scattering of gamma-rays on the shield and in the sample was considered. For a 25% efficiency detector in a small shield, about a 1% contribution to the total efficiency was measured, whereas for samples of a few hundred grams, these contributions reached 1-2%. Simple models for description of the effects are presented.
