摘　　要：ERICA程序是广泛应用于非人类物种辐射效应的评估程序。运用ERICA程序对某核电厂正常运行时陆生生物所受到的辐射剂量率进行估算和评价,鉴于ERICA程序中作为程序输入参数的特定场址的核素浓度难以获取,且程序不能对惰性气体进行计算,本文采用SRS-19模型计算核素浓度,并以半衰期较长的85Kr为例,初步尝试使用R&D 128模型对惰性气体的辐射生物影响进行估算。结果表明,两模型对ERICA程序能够起到较好的补充作用,厂址周围各类陆生生物所受辐射影响不大。ERICA code is a program widely used to assess non-human species radiation effect in the world. The radiation rate of terrestrial organisms when the nuclear power plant operates normally was calculated and evaluated through ERICA code in this paper. And considering that,the concentration of nuclide as the input parameter of ERICA code is difficult to obtain,and the inert gases such as85 Kr are not considered in ERICA code,we calculated the nuclide concentration with SRS-19 model in this paper,and take85 Kr as example,we try to calculate the radiation effect of inert gases with R&D 128 model. It was concluded that two models are good supplement to ERICA code,and the radiation effects on terrestrial organisms within radius of 80 km of the site are acceptable.
