A deterministic code was developed for the calculation of true coincidence summing correction factors and has been incorporated into the EFFTRAN tool. The approach is aimed at the analysis of extended samples measured on p-type HPGe detectors in environmental gamma-ray spectrometry and was verified against the results of a state-of-the-art full Monte Carlo code. The two sets of results matched on average within 1%. Our code requires no measurements in addition to a standard full-energy-peak calibration, has a very short run time and takes into account the spatial variation of the efficiency across the sample volume. The EFFTRAN code is free software, available from the authors on request.
开发了一种确定性代码用于计算真符合求和校正因子，并已将其纳入EFFTRAN工具中。该方法旨在分析环境伽马射线能谱法中在p型高纯锗探测器上测量的扩展样品，并与最先进的全蒙特卡罗代码的结果进行了验证。两组结果平均匹配在1%以内。除了标准的全能峰校准外，我们的代码无需进行其他测量，运行时间非常短，并考虑了样品体积内效率的空间变化。EFFTRAN代码是免费软件，可应作者要求提供。
