本文介绍用蒙特卡罗模拟方法计算大强度~(60)Co γ射线源的天空反照剂量率。计算结果给出了天空反照剂量率与一些参数的定量依赖关系。并且对这些关系曲线进行了函数拟合,给出了拟合公式。
In this paper, the Monte Carlo simulation method is used to calculate the sky-albedo dose rate for a high-intensity ~ (60) Co γ-ray source. The calculation results give the quantitative dependence of sky-albedo dose rate on some parameters. And these curves were fitted by function, and the fitting formula was given.
