A previously proposed hybrid analytical-numerical method for efficiency calibration of a NaI detector for a point γ-source is extended and applied for other shapes of sources. The shapes include line, disk, and cylindrical sources of various dimensions and locations with respect to the right circular cylindrical NaI detector. The results obtained by this method have been evaluated through comparison with Monte Carlo (MC) calculations. A relative maximum difference of 3.5% is found between the two methods.
先前提出的一种用于点 γ 源的 NaI 探测器效率校准的混合分析-数值方法得到了扩展，并应用于其他形状的源。这些形状包括相对于圆柱形 NaI 探测器的各种尺寸和位置的线、盘和圆柱形源。通过与蒙特卡罗（MC）计算的比较，对该方法获得的结果进行了评估。两种方法之间发现的相对最大差异为 3.5%。
