Abstrakt | 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 percent efficiency detector in a small shield, about a 1 percent contribution to the total efficiency was measured, whereas for samples of a few hundred grams, these contributions reached 1-2 percent. Simple models for description of the effects are presented. | |
