An efficiency calibration method has been developed to measure radioactivity of volume samples with HPGe detectors. The method has two main procedures. One is a point-source calibration at a representative point near the detector. The position of the

In general, radioactivity measurements for volume samples are performed by the γ-ray spectrometry method with germanium detectors. In the method, peak efficiency curves must be obtained for each kind of sample in advance. For the reason, usually, ma

An equation for the peak-to-total ratio, P, of a germanium detector is proposed in the following form. P=ep/et+a(V/A)+b(V/A)2/2 where ep/et is the ratio of the photoelectric to the total detection efficiency for a germanium detector, V/A is the volum

The estimation of radioactivity induced in concrete shielding is important for the decommissioning of accelerator facilities. Concentrations of (3)H and (14)C in the concrete shielding of an electron linear accelerator were measured, and the depth di
