摘要
叙述了两种电离室的制作,测量了饱和特性、轴向均匀性、灵敏度、稳定性等性能参数以及物料对^(137)Csγ射线的吸收规律。
Two kinds of high- pressure and large- volume ionization chambers with different structure are described. And performances such as saturation property, axial uniformity, sensitivity and long- term stability are studied. The absorption law of 137Cs γ - rays in materials is also found using the ionization chamber.
