摘要

对上海金鹏源（SHJPY）60Co γ辐照装置进行数学建模，运用蒙特卡罗方法（MCNP），模拟计算辐照装置在装载0.1g/cm,3, 的均匀产品情况下的剂量分布，软件模拟计算结果的统计误差控制在5%以内，模拟计算结果与实际0.1g/cm,3, 产品剂量分布测试结果比较，发现偏差的绝对值在15%(多数在8%以下)以内，模拟计算与测量数据基本吻合，计算结果可以反应产品吸收剂量的分布规律。

Abstract

The mathematical model of Shanghai JPY (SHJPY) ,60,Co γ-irradiator was established to study the dose mapping of the products treated with ,60,Co-γ irradiation. The dose distribution of the irradiator in which loaded with 0.1g/cm,3, homogenous products was simulated by Monte Carlo method (MCNP) and the statistical uncertainties of program calculation are all within 5%. Our calculation results show that the differences between measurement and computation are below 15%. However most of the differences are below 8%. The dose mapping of the product which simulated by MCNP are in good agreement with measurement data. The mathematical modeling data have confirmed the dose distribution of the products.
