摘要

采用MCNP（Monte Carlo N particle transport code）程序和经验公式两种方法进行,60,Co源辐照室的防护屏蔽计算，分析不同方法所得的辐照室外以及迷道内受照剂量率的变化情况。结果表明：从辐射防护最优化、土建经济性及实际测量等角度考虑，经验公式法的贯穿辐射计算结果偏保守；而迷道散射计算中，经验公式法方便省时，尤其是在迷道结构复杂的情况下计算，比MCNP快捷。

Abstract

MCNP (Monte Carlo N particle transport code) and the empirical equation were used for shielding calculation of a ,60,Co irradiation room. The absorbed dose rates obtained outside the irradiation room and inside a maze were studied. The calculation results of the penetrating radiation using an empirical equation was obviously bigger than that of actual measurement and would increase the construction costs. The calculation results of maze scattering showed that the empirical equation was a convenient and time-saving method, and the calculation was especially quick and easy when the maze was complex.
