摘　　要：电离室由于其具有结构简单、使用方便的特点,目前仍被广泛应用于辐射监测领域。用于X、γ射线测量时,必须研究电离室的能量响应,并通过能响补偿使其灵敏度在一定的误差范围内是与入射X、γ射线的能量无关的常数。利用蒙特卡罗方法,模拟计算了圆柱形电离室对X、γ射线的灵敏度和能量响应;并根据计算结果的规律,对圆柱形电离室的能量响应进行了补偿,给出了补偿参数的最优范围。Ionization chamber is still being widely used in radiation monitoring because of its simple structure and convenience.Used in X or gamma ray monitoring,the energy response of the chamber needs intense investigation and proper compensation filters must be designed in order to achieve a constant sensitivity which is independent of the energy of the incident X or gamma ray among a specified error range.The Monte-Carlo method is used to calculate the sensitivity and energy response characteristics of cylindrical ionization chamber to X or gamma ray.According to the results of simulation,the energy compensation of chamber is studied and the optimized compensation parameters are given.
