摘要
Abstract
Tobacco leaves contain various natural radioactive nuclides,smoking may increase internal radiation dose to the human body.This paper analyzed the 210 Po levels in 36 domestic cigarette brands and 4 foreign cigarette brands.The analysis results showed that the 210 Po content in domestic cigarettes ranged from 22.3 to 48.6 mBq/g(or 13.1 to 29.9 mBq per cigarette),with an average of 32.9 mBq/g(or 20.2 mBq per cigarette);while in foreign cigarettes,210 Po content ranged from 18.5 to 24.3 mBq/g(or 11.1 to 12.7 mBq per cigarette),with an average of 21.2 mBq/g(or 12.1 mBq per cigarette).Overall,the 210 Po content in domestic cigarettes was slightly higher than that in foreign cigarettes.Based on the 210 Po content in tobacco shreds,it was estimated that the amount of 210 Po inhaled by Chinese smokers from cigarettes was approximately from 24.85 to 150.29 mBq per day,and the internal radiation equivalent dose to the lung tissue was from 27.48 to 166.22 μSv per year.关键词
