摘　　要：目的　了解苏州市部分地区土壤中总α、总 β放射性本底水平及其变化情况。 方法　于苏州市的新区、工业园区、古城区、吴中区分别采集新鲜土壤 ,制样 ,检测总α、总 β放射性水平 ,计算 β/α比值。结果　苏州市土壤总α、总 β放射性水平范围分别是 96 2～2 6 6 7Bq/kg和 32 8～ 84 7Bq/kg,β/α比值为0 4 16。结论　苏州市土壤总α、总 β放射性水平属于正常本底。Objective To investigate the total natural radioactivity levels in the soil of part area of Suzhou city.Methods The soil samples were collected from four districts,i.e.,new area,industry-park area,old-town area and Wu-zhong area.The total α、total β levels and β/α ratio were measured.Results The α radioactivity levels in soil were between 962 Bq/kg and 2 667 Bq/kg ,the β radioactivity levels in soil were between 328 Bq/kg and 847 Bq/kg ,and β/α ratio was 0.416.Conclusions The total radioactivity levels in soil of Suzhou are in normal background.
