Paper Abstract

Objective To assess the Taikonaut's space radiation risk organ, doses have been calculated using a male voxel model. Methods A male voxel model based on MRI was built. The proton spectra were calculated by AP-8 with SPENVIS and Badhwar's GCR model. The general 3 D Monte Carlo particle and heavy ion transport code GEANT4 was used to calculate the average doses for some organs and tissues. Results After 1 g/cm2 shielding shell, the absorbed dose rate of skin is 0.6 mGy/d and effective dose rate is estimated to be 2.3 mSv/d during the SZ-5/6/7 mission. The total effective dosesof the taikonauts are estimated to be around 2.0 mSv during the SZ-5 mission, 10.9mSv during the SZ-6 mission and 6.5 mSv during the SZ-7 mission separately. Conclusion The calculated skin doses are closed to the values measured by TLDs in SZ-5/6/7, and within the range of 0.2~0.6mSv published by USA and Russia.
