摘要
为了全面分析室内氡的时空分布特征、来源和影响因素,选择了贵阳市不同地理位置的居民住宅、办公场所和公共场所,进行了为期一年的室内氡监测。贵阳市室内氡的平均浓度为(72.7±1.6)Bq/m3,低于室内空气污染国家标准,达标率98.5%。其中居民住宅、办公场所和公共场所的室内氡浓度分别为(93.46±86.93)、(74.68±40.74)、(61±26.93)Bq/m3。研究表明,室内涂料、装修程度和通风效果、小区环境等对室内氡浓度高低有显著影响,室内氡也随季节变化而发生波动。对于居民住宅和公共场所氡的室内外来源相对重要性不同。居民住宅内新楼和旧楼不同楼层室内氡的来源、影响因素和分布特征有显著差异。
Indoor radon concentrations were monitored at different dwelling houses,offices and public places to understand the sources,influence factors and the spatial and temporal variation of indoor radon in Guiyang city for one year.The mean value of indoor radon concentration in Guiyang was（72.7±1.6） Bq/m^3,which was lower than the level of State Indoor Standard,and 98.5 percent of samples reached the national standard.The average concentration of indoor radon at dwelling houses,offices and public places were（93.46±86.93） Bq/m^3,（74.68±40.74） Bq/m^3,and（61±26.93） Bq/m^3,respectively.Indoor radon was influenced by finishing materials,ventilation,surrounding of housing estates and seasons to great extent.The amount of radon from indoor and outdoor sources was different for private houses and public places.There were different sources,influence factors and distribution character of indoor radon at different floors between old and new buildings.
