摘要
[目的]了解新建高层毛坯房室内氡污染水平,分析毛坯房室内氡水平的主要影响因素。[方法]采用Model1027型连续测氡仪对11套新建高层楼房室内氡浓度进行连续检测。[结果]本次调查的毛坯房室内氡浓度为(108.073±62.074)Bq/m3;毛坯房高层室内氡浓度远低于低层室内氡浓度,地基土壤氡对新建高层毛坯房楼层较高室内氡浓度影响较小;与建筑材料表面积相比,建筑物内部体积变化对室内氡浓度的影响较显著。[结论]新建高层毛坯房室内氡浓度远高于我国居民装修住宅室内氡浓度水平。室内墙体粉刷、地面铺设瓷砖、楼层高度、建筑物表面积、体积是影响毛坯房室内氡浓度的主要因素。
[Objective] To understand radon pollution level in new blank houses; and analyze main influencing factors on indoor radon concentrations. [Methods] Measurements were made in 11 sets of new blank houses using 1 027 type professional continuous monitor on radon （Sun nuclear corporation, US）. [ Results] Radon concentration in new blank houses was （108.073±62,074） Bq/m^3. Radon levels in new blank houses were more obvious on high floors than on low floors. The effect of soil radon on radon concentrations in new higher blank houses was small. The effect of internal volume change on radon concentrauons was obvious. [Conclusion ] Radon concentrations in new blank houses are higher than average radon concentrations in renovated houses. The main influencing factors on radon concentrations in new blank houses are renovation, heights of floors,area and volume of building.
