Abstract: 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 as ⁸⁵Kr are not considered in ERICA code,we calculated the nuclide concentration with SRS-19 model in this paper,and take ⁸⁵Kr 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.

Key words: SRS-19 model, R&D 128 model, ERICA code, terrestrial organism, radiation effect assessment
