【摘要】 采用α径迹蚀刻法和RAD7连续测氡仪,于2008年8月至2009年8月在乌鲁木齐全市范围内选取楼房、平房、别墅等共79套房83个点位,进行了室内氡浓度的测量。分析结果表明,乌鲁木齐市室内氡浓度的均值为55.4Bq/m3,范围为19～154Bq/m3,冬季室内氡浓度明显大于夏季,春秋季浓度相当;燃煤可能是造成室内氡浓度偏高的主要原因,并据此提出了预防和降低室内氡的具体对策。更多还原

【Abstract】 During August 2008 to August 2009,both alpha etched track detector technique and RAD7 radon monitor were used to monitor the indoor radon concentrations at 83 sites of 79 buildings,bungalows and villas in Urumqi region.The results indicate that the indoor radon concentrations are in the range of 19—154 Bq/m3,with an average of 55.4 Bq/m3,significantly higher in winter than in summer,and equal in spring and autumn.The coal burning may be the main cause of higher radon concentrations.As a result,the prevention and control measures are put forward.更多还原
