摘要：

A new technique to calculate coincidence-summing corrections in gamma-ray spectroscopy developed by Semkow et al. [Nucl. Instr. and Meth. A290 (1990) 437] was extended to incorporate coincidence-summing effects due to X-rays. The technique was experimentally validated in the case of Ce-139 measurement. It is shown how the technique can be applied for the calculation of the full-energy peak and of total detection efficiencies. In addition, an absolute method for measuring the activity of a point source is proposed and demonstrated in the case of Ce-139. Finally it is shown how this improved technique can be applied to assess the ratios of the probabilities for emission of X-rays and for parameter optimization in peak-evaluating procedures.
