The Monte-Carlo code PENELOPE for Ionisation Chamber Simulation Method has been applied for the calculation of ionisation-chamber (IC) calibration factors. Measuring only a few radionuclides well selected within the relevant energy range, and determining an adjustable parameter, commonly used radionuclides can be measured without any specific calibration. The simulation revealed a discontinuity in the IC response as a function of photon energy and its dependence on the chemical composition of the radioactive solution.
用于电离室模拟方法的蒙特卡罗代码PENELOPE已应用于电离室(IC)校准因子的计算。仅测量相关能量范围内精心挑选的少数几种放射性核素,并确定一个可调参数,就可以在无需任何特定校准的情况下测量常用的放射性核素。模拟结果揭示了电离室响应随光子能量的不连续性及其对放射性溶液化学成分的依赖性。
