Angular response of a HPGe detector to gamma-rays in in situ measurements.
The angular response of a HPGe detector used in in situ measurements was determined empirically as a function of gamma-ray energy at two source-detector geometries--the standard 1 m and the non-standard 0.1 m heights above ground. Values calculated by a Monte Carlo code were found to agree well with the experimental values. The code is thus labor-saving, because it can spare many measurements required for the empirical determination of the angular response in an unknown experimental configuration.
