Abstract
To establish a dosimetric model for zebrafish(Danio rerio)to obtain the dose coefficient and dose rate of zebrafish for 137Cs,and to provide effective technical means and data for radionuclide discharge from nuclear facilities into the environment.The zebrafish concentration factor(CR)was obtained by feeding zebrafish with a 1 000 Bq/L 137Cs aqueous solution in the laboratory.Holistic and simplified anatomical models were established for zebrafish,and the internal and external irradiation deposition energies of radionuclide 137Cs particles in zebrafish were obtained by Monte Carlo simulations.The dose coefficient and dose rate of 137Cs for zebrafish were calculated according to the formula.For the holistic zebrafish model,the 137Cs dose coefficient was 6.77×10-3(mGy·h-1)/(Bq·kg-1)and calculated dose coefficient of external irradiation was 3.67×10-2(mGy·h-1)/(Bq·kg-1).In the simplified anatomical model,the 137Cs dose coefficient and calculated dose coefficient of external irradiation were 1.24×10-3(mGy·h-1)/(Bq·kg-1)and 2.66×10-2(mGy·h-1)/(Bq·kg-1),respectively.The activity concentrations of 137Cs reached 170 Bq/L and 330 Bq/L when using the zebrafish holistic and simplified anatomical models,respectively.The calculated dose rate of zebrafish exceeded the ERICA screening benchmark(10 mGy/h).In this study,holistic and simplified anatomical models were established for zebrafish based on Monte Carlo simulations,and the results were compared using the ERICA software tool.The calculated results were of the same order of magnitude,thereby demonstrating that the established zebrafish dosimetry model can be applied to environmental radiation impact assessments.关键词
