基于点核法的γ辐射剂量计算软件设计

Design of Gamma Radiation Dose Calculation Software Based on Point Kernel Method

为满足核设施退役过程中需要大量剂量计算要求,利用C#4.0编程语言开发了基于点核方法的γ剂量计算程序PKShield.该程序包含传统点核程序QAD-CGPIC的大部分特性,并且提供了数据输入的图形界面,扩充了放射性源的几何类型.PKShield能够计算具有能谱的多放射性源的剂量分布,且具有较快的计算效率.为了验证PKShield计算方法的有效性和正确性,利用所开发的PKShield与MCNP5进行剂量计算结果比较,结果表明开发的PKShield程序能够正确、有效地计算γ辐射剂量.

In order to meet the requirement of a large amount of dose calculation in the decommissioning process of nuclear facilities,aγdose calculation program PKShield based on point kernel method was developed using C#4.0 programming language.This program contains most of the features of the traditional point core program QAD-CGPIC,and provides a graphical interface for data input,and extends the geometric types of radioactive sources.PKShield can calculate the dose distribution of multiple radioactive sources with energy spectrum and has a fast calculation efficiency.In order to verify the validity and correctness of PKShield calculation method,the developed PKShield was compared with MCNP5 dose calculation results.The results show that the developed PKShield program can correctly and effectively calculateγradiation dose.
