辐射致癌的问题历来受到人们的重视。最近召开的第一届国际小剂量电离辐射生物效应讨论会对这一问题也进行了讨论。现根据会议资料作一简要综述。(一)流行病学调刃查流行病学研究历来是我们探讨疾病发生、发展、转归和相关因素的重方法之一。对于辐射致癌这一影响深远的课题,流行病学研究更是一种非常重要的切实可行的手段.在这次讨论会上,有不少论文从不同侧面对这一问题进行了讨论。在一篇题为“受辐射人员致癌危险性估计一技术上的困难与不精确性”的报告中提到,估计低剂量电离辐射致癌危险性需要对实验数据、假设、方法及不精确性 The problem of radiation-induced cancer has always been people’s attention. The first International Symposium on the Biological Effects of Ionizing Radiation in Small Volumes held recently also discussed this issue. Now based on the meeting information for a brief review. (A) Epidemiology Research on epidemiological epidemiology has always been one of the most important ways to explore the occurrence, development, outcome and related factors of diseases. Epidemiological research is a very important and practical measure for the far-reaching issue of radiation carcinogenesis, and many papers discussed this issue from different aspects at this symposium. In a report titled “Technical Difficulties and Inaccuracies in Carcinoid Risk Assessment by Radiation Workers,” it is mentioned that estimating the carcinogenic risk of low doses of ionizing radiation requires experimental data, assumptions, methods, and inaccuracies
