| Abstract:: |
| Objective To establish a simplified anatomical model with the selected rabbits widely distributed in China's dry region as the reference species and compare the result of internal exposure dose coefficients based on the present mode and ERICA.Methods A simplified anatomical model based on anatomy and geometry was established for rabbits. Combined with Monte Carlo program, the deposited energy of radionuclide particles in rabbit tissues/organs was obtained, and the internal and external exposure dose coefficient for rabbits was calculated following the empirical formula.Results Simplified anatomy model-based dose coefficients were 129I 4.81 × 10-6, 137Cs 4.34 × 10-5, and 134Cs 3.81 × 10-5(μGy·h-1)/(Bq·kg-1) for internal exposure and 129I 3.16 × 10-7,137Cs 2.39 × 10-4 and 134Cs 6.22 × 10-4(μGy·h-1)/(Bq· kg-1) for external exposure. respectively. ERICA-based dose coefficients were 129I 4.44 × 10-5, 137Cs 1.94 × 10-4 and 134Cs 2.34 × 10-4(μGy·h-1)/(Bq·kg-1) for internal exposure and 129I 2.19 × 10-6, 137Cs 2.52 × 10-4 and 134Cs 6.95 × 10-4(μGy·h-1)/(Bq·kg-1) for external exposure, respectively.Conclusions The simplified anatomical model established is based on the measured data and focuses on the radiation doses to biological tissues/organs, and the calculated result based on the present model are closer to the actual situation, and can provide reference values for the reference biological evaluation of non-human species. |
