腾冲县火山地质博物馆建筑地基及周围土壤氡浓度分析评价

Analysis and Evaluation of Radon Concentration in the Foundation and Surrounding Soil of the Volcano Geological Museum in Teng chong County

指出了居家环境一直为人们普遍关注,建筑室内氡污染主要来源于建筑物地基及周围表层土壤、建筑材料、家用燃气、生活用水、室外空气、地下深部的氡6类,然而按世界平均水平计算,来源于建筑物地基及周围土壤的氡浓度约占室内氡浓度的60.4%,故针对腾冲县火山地质博物馆建筑地基及周围土壤氡浓度进行了检测和分析,提出了相应的建议,以更好的服务于游客。

Indoor air pollution has been widely concerned by researchers at home and abroad.There is a linear relationship between the incidence of lung cancer in uranium mining workers and the concentration of radon and its children in the underground air in Germany since the 1950 s.Radon pollution is getting more and more attention.Since the 21 st century,the average indoor radon concentration in China is 46.1 Bq/m3,respectively,up 57%and 42%in the 1980 s and 1990 s.Indoor radon pollution in buildings mainly comes from the building foundation and surrounding surface soil,building materials,domestic gas,domestic water,outdoor air,and radon in the deep underground.However,according to the world average,the radon concentration from the foundation and surrounding soil accounts for 60.4%of the indoor radon concentration.Therefore,the radon concentration of the building foundation and surrounding soil in Tengchong county are analyzed andsuggestions are provided to better serve tourists.
