本文介绍一种估算钴圃围墙外散射γ照射量率的等效圆柱形面源方法,给出了计算照射量率分布的近似公式。在选定条件下,估算结果与实测数据符合得较好。
In this paper, an equivalent cylindrical surface source method for estimating the γ-ray scattering rate outside the Cobb fence is presented. An approximate formula for calculating the radiation dose rate distribution is given. Under the selected conditions, the estimation results are in good agreement with the measured data.
