摘要 利用MCNP4C程序计算了一种高灵敏度环境中子剂量当量仪的响应曲线。计算结果在感兴趣能量区间与ICRP建议书中的H*(10)曲线符合较好,通过实验验证,计算结果与实验数据相对偏差在-21.6%以内(对中子要求偏差在±50%以内),实验表明,用MCNP程序优化设计探测器可提高设计效率,并可同时为实验验证提供参考数据。 The energy response of a high sensitivity environmental neutron dose equivalent meter is calculated by MCNP4c code. The calculated response curve agrees with H^*(10) curve in ICRP 74 report in interesting neutron energy regions. By comparison between the experimental results and the calculated values, the relative deviation is -21.6%. Experiments show that MCNP4C code can be applied to calculate neutron response for the high sensitivity environmental neutron dose equivalent meter, and it can also raise the work efficiency and help to analyze the experimental results.
