In order to meet the energy needs of sustainable economic development , actively develop nuclear power has become an important means to improve energy supply in China , to change the energy structure . In the enormous economic and social benefits at the same time , the nuclear power plant during normal operation, inevitably there will be airborne radionuclides discharged . Of airborne radioactive effluents be around radiation environment and what impact have been given a lot of attention . The determination of the concentration of radionuclides is the basis and prerequisite of the environmental assessment, radiation protection and other related work . In this paper, a Gaussian plume model based AIRDOS-EPA program simulation of diffusion of radionuclides released in the normal operation of the Daya Bay Nuclear Power Station in the atmosphere . Model the actual situation of the Daya Bay Nuclear Power Station , the relevant amendments , and Daya Bay Nuclear Power Station measured weather data , calculate the annual average concentration in the surrounding ground , ground deposition rate and the atmosphere of airborne radionuclides from the Daya Bay Nuclear Power Station in 2001 diffusion factor and calculated air and soil radionuclide concentration compared with the natural background values ??and actual monitoring value . Further integrate the Daya Bay Nuclear Power Station 80 km around the population distribution , agriculture , farming, animal husbandry , such as a large number of statistics , reasonable doses mode , calculate the annual collective dose of the surrounding residents and individual effective dose , and the calculated results with other human activities were compared. The comparative analysis of the calculated radionuclide concentrations and radiation dose , radiation environment around the quantitative reference information for the understanding of the Daya Bay Nuclear Power Station .
