摘要
为准确划定工业γ探伤机的控制区与监督区,应用MCNP5程序构建了移动式γ射线机计算模型。该模型充分考虑了工业γ探伤机散射对周围剂量的贡献,可有效地应用于工业γ探伤机控制区与监督区的划定与环境影响评价。实验结果表明:MCNP程序计算结果与经验公式结果基本一致,MC模拟方法对移动式工业γ射线机周边辐射剂量估算是可行的。
In order to accurately delineate the control and supervision areas of the industrial gamma - radio- graphy ,we construct a model of mobile gamma ray machine by using the MCNP5 program. The model takes into account the contribution of the scattering of the industrial gamma - radiography to the dose. It can be effectively applied to the delineation for the control and supervision areas of the industrial gamma - radiography and the en- vironmental impact assessment. The experimental results show that the results of the MCNP program are basical- ly consistent with the empirical formula. The MC simulation method is feasible for the radiation dose estimation of the mobile industrial gamma - radiography.
