Application Method Study of Erica Model and R&D128 Model in Radiological Impact Assessment of Terrestrial Organisms

ERICA model and R&D128 model are programs widely used to assess non-human species radiation effect. Two models were briefly introduced in this paper, and taking a coastal NPP in China as example, the radiation dose rate of terrestrial organisms near the NPP was calculated and the parameters were compared. It was concluded that the calculation result of ERICA model was more conservative than R&D128 model for 3H and 14C, but the calculation result of R&D128 model was more conservative than ERICA model for most of other nuclides except for 3H and 14C. The nuclides and reference organisms of ERICA model were more comprehensive, but the radiation dose rate caused by noble gases could be calculated by R&D128 model, the radiological impact on terrestrial organisms of noble gases can be illuminated to a certain extent. It was suggested that the radiation impact of noble gases and other nuclides on terrestrial organisms should be calculated with R&D128 model and ERICA model separately. The application method of two models in radiological impact assessment of terrestrial organisms was established.
