摘要
采用蒙特卡洛程序MCNP计算了介质水对于不同能量X射线的能量吸收系数,并给出了相应的光子通量-剂量转换因子,可用于辐照事例中对于薄膜剂量片测试结果的模拟计算,从而实现对实际照射环境的蒙特卡洛模型优化,以获得照射对象较为准确的吸收剂量计算结果.
Mass energy absorption coefficient in water of X-ray with different energy was calculated by Monte Carlo program MCNP, corresponding flux-dose factor was given also. With these two parameters, absorbed dose for radiochromic films at specific locations can be easily calculated, and be used to optimize model for simulating X-ray irradiation events, to eventually achieve accurate absorbed dose for irradiated objects.
