| 摘 要： | 目的验证和探讨在高能同步辐射光源辐射屏蔽计算中半经验公式和蒙特卡罗模拟方法的一致性和适用性。方法分别采用半经验公式和蒙特卡罗模拟独立计算单电子打靶时屏蔽体外产生的周围剂量当量。结果Jenkins半经验公式计算结果与蒙特卡罗模拟结果比值范围为111%~153%,Sakano半经验公式计算结果与蒙特卡罗模拟结果比值为201%。结论对单一屏蔽材料,半经验公式可简单、保守地完成对高能电子加速器的屏蔽计算。对于多种屏蔽材料,宜采用蒙特卡罗模拟方法。

| Abstract: | Objective To verify and discuss the consistency and applicability of the semi empirical formula and Monte Carlo simulation method in the radiation shielding calculation for high energy synchrotron radiation source. Methods The semi empirical formula and Monte Carlo simulation were used to calculate the ambient dose equivalent outside of the shielding. Results The ratio of Jenkins semi empirical formula result to Monte Carlo simulation result was 111%-153%. The ratio of Sakano semi empirical formula result to Monte Carlo simulation result was 201%. Conclusions For a single shielding material, the semi empirical formula can be simple and conservative to complete the shielding calculation for high-energy electron accelerator. For a variety of shielding materials, Monte Carlo simulation method should be used. |
