210Po在吸烟过程中的分布

运用α能谱法分别测量了烟丝、烟灰、滤嘴中210Po的含量，研究了吸烟过程中210Po在香烟不同部分的分布情况。通过湿法消解方式分别消解了7种品牌香烟烟丝、烟灰以及滤嘴。测量结果表明，7种品牌香烟烟丝中210Po的比活度范围是（28.13±1.75）-（47.78±2.83） mBq·g-1，均值为36.60mBq·g-1；7种品牌香烟每支烟丝中210Po的比活度范围是（14.39±0.90）-（27.91±1.65） mBq，均值为20.77 mBq。在吸烟过程中，平均13.24%的210Po会滞留在烟灰中，平均14.39%的210Po会滞留在滤嘴中，平均72.37%的210Po会转移到燃烧烟...

Summary:运用α能谱法分别测量了烟丝、烟灰、滤嘴中210Po的含量，研究了吸烟过程中210Po在香烟不同部分的分布情况。通过湿法消解方式分别消解了7种品牌香烟烟丝、烟灰以及滤嘴。测量结果表明，7种品牌香烟烟丝中210Po的比活度范围是（28.13±1.75）-（47.78±2.83） mBq·g-1，均值为36.60mBq·g-1；7种品牌香烟每支烟丝中210Po的比活度范围是（14.39±0.90）-（27.91±1.65） mBq，均值为20.77 mBq。在吸烟过程中，平均13.24%的210Po会滞留在烟灰中，平均14.39%的210Po会滞留在滤嘴中，平均72.37%的210Po会转移到燃烧烟雾中。

Background： Due to direct deposition on leaves or root uptake, the tobacco leaves may contain 210Po in significant concentration. There have been many surveys on the 210Po activity concentration in cigarettes, yet few researches on the distribution of 210Po during smoking. Purpose： The study aims to research the distribution of 210Po during smoking. Methods： 209Po was used for chemical recovery calculation and 210Po was measured by α spectrometry using a passivated implanted planar silicon （PIPS） detector after chemical leaching and spontaneous on silver disk. The 210Po of fresh tobacco, filter, post-smoking filter and cigarette ash were measured. The 210Po activity concentration in smoke was determined on the basis of above data. Resul
