为了开展反应堆压力容器中子辐照损伤、射线辐照生物效应等方面的研究,研究了蒙特卡罗通量计算技巧,建立了形成大范围粒子的精细通量分布的快速方法,并可以根据介质的不同转换为剂量场分布。 利用上述手段,进行了大探伤加速器实时成像技术中的研究和体部伽玛刀准直器辅助设计中的应用。 基于人体内剂量场计算的粒子源组织间三维立体定向肿瘤治疗计划系统也正在研制中,很快将投放市场。 In order to carry out research on neutron irradiation damage and radiation effects in reactor pressure vessels, the Monte Carlo calculation technique has been studied and a fast method of forming fine flux distribution in a wide range of particles has been established. According to the medium The difference is converted to dose field distribution. Using the above methods, the research of real-time imaging technology of large-scale flaw detection accelerator and the application of auxiliary design of body gamma knife collimator were carried out. A three-dimensional stereotactic tumor treatment planning system based on the dose field in the human body is also under development and will soon be put on the market.
