摘　　要：叙述了包括点源随距离衰减,射线贯穿屏蔽体减弱、反散射剂量估算、在无限、半无限空间散射剂量估算、有效剂量当量与集体有效剂量当量估算等γ放射性同位素源环保评价实用模式,可供辐射环保评价工作者参考。This article systematically describes a practical environmental impact assessment model of γ radioisotope source.Its contents include the attenuation of point source with the change of distance,the weakening of radiation through the shield,the estimation of back-scattered dose,the estimation of scattered dose in an infinite or semi-infinite half-space,and the estimation of effective dose equivalent and collective effective dose equivalent,to which workers of radiation environmental evaluation can refer.
