【摘要】 采用固体核径迹法,于2007年4月至2008年3月测量了石家庄不同地区、不同建筑结构、不同装修材料、以及不同建筑年代的95间居室内氡浓度及其在不同季度的变化。调查结果表明,石家庄地区居室氡浓度平均值为(31.8±16.5)Bq/m3;建筑材料可能是影响居室氡浓度的主要因素;室内氡浓度随季度变化明显,一、四季度明显高于二、三季度;选择恰当的材料进行装修和保持良好的室内通风可以起到降低室内氡浓度的效果。更多还原

【Abstract】 Solid state nuclear track method was used from April 2007 to March 2008 to measure indoor radon concentration in 95 living rooms in different regions of Shijiazhuang and their variations with construction structures,decoration materials,years and quarters.The results show that the average indoor radon concentration in Shijiazhuang is(31.8±16.5)Bq/m3.The major factor influencing the concentration of radon may be building materials.Indoor radon concentration varies significantly with the quarters,much higher in first and forth quarters than in second and third quarters.Selecting appropriate materials for decoration and maintaining good indoor ventilation can play a role in reducing indoor radon concentration.更多还原
