摘要
从核物理和核防护等理论知识出发,介绍了β-射线、γ射线和内转换电子等内照射对人体的全身所致的全身最大容许负荷量的计算方法和计算结果。这些辐射是137Cs和60Co等放射性核素被摄入体内时产生的,讨论了进行计算所应用的各种条件。
Based on the theories and knowlelge of nuclear physics and nuclear protection, the paper introduces the calculations and results of the maximal allowable load for human body of intemal irradiation of β-, γ rays and intemal transfer electron. The irradiation come from radioactive nuclide taken into the body, such as 137 Cs, 60Co, H analyzes various factors involved in the calculation.
