| Abstract:: |
| Objective To assess impact of radiation from nuclear power on the surrounding environment, a dose assessment model was constructed and relevant dose coefficients were determined through refined animal models. Methods Zebrafish is one of the most important aquatic model animals in the radiation hazard assessment of nuclear power liquid effluent. A geometric model of zebrafish containing internal bones and visceral organ was established for dose estimation. The internal and external dose coefficients (DC) of the zebrafish model were calculated by Monte Carlo method with seven nuclides as the source term, 3H,40K,58Co,60Co,110Ag,134Cs,137Cs, which are common in nuclear liquid effluents and environmental monitoring. Results The level of nuclide gamma energy determines dose coefficients for external radiation. The dose coefficients of most nuclides in internal organs was higher than that in whole body, and the internal organ dose of 58Co was 165% higher than that in whole body. The internal radiation dose coefficients of the model established in this study was relatively high, and the internal radiation dose coefficients caused by 60Co was 2.6 times of existing ellipsoid model, which suggested that the different internal materials and the choice of different particle types would affect the energy deposition. Conclusions Refining of model animals is important. Accurate assessment of the organs dose coefficients of model animals is helpful to assess the radiation effects on non-human species. |
