摘要
为验证MCNP程序进行γ射线透过率模拟的准确性,利用MCNP程序模拟了能量分别为2、5、8、10 MeV的γ射线穿过不同厚度的铅和铁后的透过率值。模拟结果表明,利用MCNP程序进行γ射线透过率模拟,与按射线衰减规律的计算值相符。
In order to test the validity of the MCNP code used in the transmission ratio of γ-ray, the transmission ratios of different energy γ-rays penetrating the Pb and Fe with different thickness were simulated in this paper. It was shown that the simulation results are consistent with the theoretical calculations in the range of error, and the Monte Carlo method is effective in simulating the transmission ratio of γ-ray.
