摘　　要：假设核动力舰船发生放射性物质泄漏事件,建立水立方模型与含骨层的水立方模型,选取多种能量的光子源,通过蒙特卡洛粒子输运程序MCNP5对模型关注栅元进行能量沉积模拟计算。结果表明,在制定核动力航母的辐射防护系统初步方案时,不仅要从宏观层面考虑到船员的年平均有效吸收剂量,还有必要结合人体各个器官的耐受剂量特点,对各器官的年当量剂量做出严格的规定。Assuming a possible incident of radioactive material leakage occurred in the nuclear-powered ship, a water phan- tom and a water phantom containing a bone layer were established respectively. Using MCNP5, energy deposition in typical cells was calculated with some kinds of photon sources. The results showed that when making plans for radiation protection of the nu- clear-powered ship, strict rules of annual equivalent dose for different organs combining their characteristic are necessitated.
