摘　　要：花岗石是重要的建筑材料,但大部分地区的花岗石辐射比较严重,并且很难准确直观地评估出危害风险的高低。通过对花岗石辐射风险评价方法的探讨,采用环境风险评估作为切入点,以区域风险的高低作为评估标准,判断任何个体进入这个区域是否为高风险区域,将环境的辐射程度与人员暴露在危险环境中的频繁程度联系在一起,形成了一套简单易行的半定量评价方法,并作实证分析,为政府的管理或居民的家庭装饰选择提供了科学的依据。Granite is an important building material, but the radiation of granite in most areas is more severe,and it is difficult to assess the degree of hazard and risk accurately and visually. Through the discussion on risk assessment method of radiation by granite, by adopting environmental risk assessment as a starting point, the level of regional risk was taken as assessment standard to judge whether the region is high-risk area when any person enter this area, the extent of environment radiation was related to the frequency of personnel exposure in hazardous environment, a semi-quantitative assessment method being simple and feasible was formed, and the practical case analysis was con-ducted. It provides a scientific basis for the government administration or the choose of home decoration for the resi-dents.
