一种简易的γ光子剂量学用组织模拟材料

A simple tissue simulated material for y photon dosimetry

研制了一种由石腊、碳、硫及软木粉组成的γ组织模拟材料,其有效原子序数Z_e=7.51;电子密度为ρ_e=3.34×10^(23)e/g:质量密度ρ=1.003g/cm^3,能同时满足与肌肉组织基本一致的条件,该材料可适用于制成模体,在一些辐射实验研究中也是一种水的较好替代物。

This paper describes a tissue simulated material, which is composed of wax and car-bon, sulphur and cork powders, with effective atomic number(Ze) of 7.51, electron density (ρe) of 3.34×1023 e/g and density (ρ) of 1.003 g/cm3. These parameters are essentially in agreement with those of muscle tissue. It can also be used as an approprite substitute for water in some radiation studies.
