【摘要】 对广东省 4座温泉宾馆室内外氡(222Rn)浓度和温泉水氡浓度进行研究,同时利用便携式探测器对室内外 PM10,PM2.5,CO2和CO 等污染物暴露水平进行直接测定.结果表明,温泉宾馆室内使用温泉水时氡浓度明显高于广东省室内平均氡浓度.除 CO 外,室内 PM10,PM2.5 和CO2 浓度都较高,其中 PM10 和 CO2 的超标率分别达到 67%和 89%.说明温泉宾馆室内不仅存在一般性污染物,而且存在高浓度的 Rn. 222更多还原

【Abstract】 Radon (222Rn) concentrations in indoor and outdoor air, as well as in hot spring waters, were studied in four hot spring hotels in Guangdong province; meanwhile PM10, PM2.5, CO2and CO pollutants exposure levels were determined directly with portable detector. Radon concentration in the hot spring hotel rooms at use of hot spring was higher markedly than the average indoor radon concentration of Guangdong province. Indoor PM10, PM2.5 and CO2 concentrations except CO were relatively high, in which PM10 and CO2 exceeded the standards up to 67% and 89% respectively. Apart from ordinary pollutants, hot spring hotels had higher222 Rn concentration in their rooms.更多还原
