高气压电离室能量响应的模拟计算

Monte Carlo Simulation of Energy Response of Ionization Chamber

高气压电离室因其能量响应好而被广泛应用于环境γ本底测量。电离室外壳形状及材料的选择对其能量响应的影响非常大,本文采用蒙特卡罗方法对AGM-5型电离室的能量响应做了模拟计算,计算结果与实验刻度值吻合得比较好。

Ionization chamber is often used to detect the background gamma radiation due to its good enerrgy, response. The energy response of ionization chamber is determined by the parameters of geometry, materials and gas pressure. In this paper, the Monte Carlo method is used to perform the energy response of ionization chamber with the type of AGM-5. The results of Monte Carlo simulation show good agreement with the data obtained by experimental method.
