By using a tissue-equivalent (TE) ionization chamber filled with TE gas and a magnesium ionization chamber filled with argon gas as the dosimeter pair for the twin-chamber method, the authors obtained the neutron and gamma-ray components of the radiation dose from californium 252 (252Cf). The distribution of dose components as a function of different phantom dimensions was determined. The effect of neutron absorption and scattering was evaluated, as well as the absorption and production of gamma rays in the phantom. The results can be used for improvement of 252 Cf dosimetry when using a body of finite dimensions.
通过使用一个充满组织等效（TE）气体的组织等效（TE）电离室和一个充满氩气的镁电离室作为双室法的剂量计对，作者获得了来自锎252（²⁵²Cf）的辐射剂量的中子和伽马射线成分。确定了剂量成分随不同模体尺寸的分布。评估了中子吸收和散射的影响，以及模体中伽马射线的吸收和产生。这些结果可用于在使用有限尺寸的人体时改进²⁵²Cf剂量测定法。
