水中浸没γ外照射剂量率转换系数计算方法研究

Abstract

Abstract: The point source spherical shell model was established by Monte Carlo software, and the effective distances of 30 mono-energy gamma rays with energies in the range of 10 keV-10 MeV in water were quickly calculated. Using three methods of Monte Carlo method F6 card, F4 card combined with FM4 card, *F8 card, the radioactivity concentration-dose rate conversion coefficients of mono-energy gamma-rays and 19 kinds of nuclides for reference person water immersion were calculated. The calculation results show that the relative deviations are within ±10% compared with the FGR 12 report and FGR 15 report of the US Energy Agency using the MIRD model and the ICRP No. 144 using the voxel model. The calculation method can provide a reference for rapid engineering calculation.

Key words: water immersion external exposure, dose rate conversion coefficient, effective distance, Monte Carlo method
