目的为了解有一定历史年代的建筑室内氡浓度水平,为保障公众健康提供有效的氡的数据资料并提出可行的解决方法。方法发放调查问卷,采用卡方检验统计分析;使用RAD-7连续测氡仪,测量室内氡浓度,采用单因素方差统计方法分析。结果调查外滩9栋办公室楼宇室内氡浓度,范围在0.2~199.1 Bq·m~(-3),几何均数为44.2Bq·m~(-3),不同建筑室内氡浓度差异有统计学意义,不同建筑结构的室内氡浓度差异无统计学意义。结论被调查办公室楼室内氡浓度都在正常范围内,人们在办公室受到氡污染的威胁更大,需要加强防护。
Objective To understand the indoor radon concentration in a certain historical era and to provide effective radon data for public health and to propose feasible solutions. Methods Questionnaire was released and analyzed by chi-square test. RAD-7 continuous radon meter was used to measure indoor radon concentration, and single factor analysis of variance was used to analyze the results. Results The indoor radon concentration of nine buildings in the Bund was investigated in the range of 0.2-199.1 Bq · m -3 with a geometric mean of 44.2 Bq · m -3. The radon concentrations in different buildings were statistically significant, There was no significant difference in indoor radon concentration in different buildings. Conclusion The concentration of radon in the surveyed office buildings is within the normal range, and people are threatened with radon pollution in the office more, and the protection needs to be strengthened.
