| 摘 要： | 本文报道了16种国产香烟和2种进口香烟中~(210)Po 含量的测定结果。香烟经 HNO_3-H_2O_2-HClO_4湿式灰化法处理后,用镍片自沉积法测定。测定结果表明,国产香烟平均每支~(210)Po 含量为28.8 mBq,进口香烟为14.3 mBq。在一次标准吸烟过程中,一支香烟所含的~(210)Po 约24%转移到主流烟雾中,44%在烟灰中,17%在烟嘴中。纸纤维加二醋酸纤维的混合滤嘴对~(210)Po 的过滤效率最高,纸纤维加二醋酸纤维加活性炭添加剂的复合滤嘴次之,纯二醋酸纤维滤嘴最差。每日吸一包国产香烟的人30 a 所受的肺组织累积剂量当量为5.2×10~(-2)Sv。

| Abstract: | The contents of ~(210)Po in 16 kinds of homemade cigarettes and 2 kinds of imported cigarettesare reported in this paper.The average ~(210)Po content in a homemade cigarette was determined to be28.8 mBq,and for imported cigarette it was 14.3 mBq.In a standard smoking process it was foundthat of the ~(210)Po content about 24% wastransferred into the inhaled smoke and 44% remained in thecigarette ash,17% in the cigarette stump.The cumulative lung dose equivalent recieved in 30 yearsby a smoker who smokes one pack of cigarette daily was estimated to be about 0.52 mSv. |
