摘要
目的 介绍一种辐射应急情况下简化的可快速估算外照射剂量的通用方法,并对该方法进行计算机应用软件设计.方法 辐射应急情况下外照射剂量评价通用方法依据IAEA的相关文献报告,利用计算机编程开发工具Visual Basic 6.0,对外照射剂量评价通用方法进行软件化设计.结果 该方法可较好地应用于辐射事故的应急处理,利用实际发生的辐射事故数据代入本方法计算机软件中,比较其计算结果,最大偏差为40%,最小偏差为6%,与实际辐射事故现场模拟剂量基本相符.结论 外照射剂量评价通用方法能够提供辐射事故应急响应的实际指导,该设计软件使辐射应急人员能够更加方便、快速并且准确地进行剂量评价,为采取响应行动提供科学依据.
Objective To describe a simplified generic procedure to evaluate the external exposure dose evaluation in radiological emergency, and to compile the corresponding computer software. Methods Based on the related reports of IAEA, this generic procedure of external exposure dose evaluation in radiological emergency was compiled to computer software by Visual Basic 6.0. Results The generic procedure for evaluation of external exposure dose could be used in the external exposure radiation accident emergency. The actual accident data were input in this software, then the results from this software agreed with those of the actual accident well. The maximum error was 40% , and the minimum error was 6%.Conclusions The generic procedure for evaluation of external exposure dose could provide practical emergency response guidance. The software might help to evaluate the accidental dose more quickly and accurately, and provide scientific basis to take the immediate response actions.
