目的研究10 Me V工业辐照电子加速器辐射防护计算方法。方法通过查图法和MCNP5计算了10 Me V工业辐照电子加速器轰击铁靶时90°方向、180°方向的X射线发射率和90°方向、180°方向上不同混凝土屏蔽厚度处的辐射剂量率。结果计算得到的0°方向和90°方向X射线发射率比较吻合。结论 90°方向、180°方向辐射防护计算时,理论模式比MCNP5偏安全。
Objective To study the radiation protection calculation method of 10 Me V industrial irradiation electron accelerator. Methods The X-ray emissivities of 90 ° and 180 ° at 10 Me V industrial electron imposition electron impact accelerator and the dose of radiation at different shielding depths in the direction of 90 ° and 180 ° were calculated by the charpy chart and MCNP5. rate. The results show that the 0 ° direction coincides with the 90 ° X-ray emissivity. Conclusion The theoretical model is safer than MCNP5 when calculating the radiation protection in 90 ° and 180 ° directions.
