摘要

运用α能谱法分别测量了烟丝、烟灰、滤嘴中

210

Po的含量，研究了吸烟过程中

210

Po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

210

Po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

210

Po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

210

Po会滞留在烟灰中，平均14.39%的

210

Po会滞留在滤嘴中，平均72.37%的

210

Po会转移到燃烧烟雾中。

Abstract

Background

Due to direct deposition on leaves or root uptake

the tobacco leaves may contain

210

Po in significant concentration. There have been many surveys on the

210

Po activity concentration in cigarettes

yet few researches on the distribution of

210

Po during smoking.

Purpose

The study aims to research the distribution of

210

Po during smoking.

Methods

209

Po was used for chemical recovery calculation and

210

Po was measured by α spectrometry using a passivated implanted planar silicon (PIPS) detector after chemical leaching and spontaneous on silver disk. The

210

Po of fresh tobacco

filter

post-smoking filter and cigarette ash were measured. The

210

Po activity concentration in smoke was determined on the basis of above data.

Results

The

210

Po activity concentration of the 7 types of cigarettes ranged from (28.13±1.75) mBq·g

-1

to (47.78±2.83) mBq·g

-1

and the average is 36.60mBq·g

-1

. On average

about 13.24% of total

210

Po was retained in the cigarette ash

about 14.39% of total

210

Po was retained in the filter.

Conclusion

About 72.37% of

210

Po was transferred in the cigarette smoke

which may be deposited in the lung tissues.
