摘要：

A reverse electrode coaxial Ge detector has been used to determine the 46.5 keV gamma-ray emission rates of several sources of 210Pb. The effect of the escape peaks was carefully taken into account when determining the areas of the full-energy peaks for the calibration of the spectrometer. Source activities were measured by means of an improved 2πα counting techniques. The emission probability of the 46.5 keV gamma ray was found to be 0.0426±0.0007. This nuclide can be used as a low-energy gamma-ray standard as demonstrated in the calibration of 129I monitors. © 1990.
