摘要
本文分析了中国、日本等国生产的40种牌号香烟中^(210)Pb,^(210)Po的含量。结果表明,中国香烟中^(210)Pb的含量变化范围为0.0289~0.0566Bq/g,平均值为0.0419Bq/g;^(210)Po的含量变化范围为0.0155~0.0568Bq/g,平均值为0.0349Bq/g。中国香烟中^(210)Pb,^(210)Po的含量高于日本等国生产的香烟。
The contents of Pb-210 and Po-210 in 40 brands tobacco produced in China, Japan and other countries were analysed. The results showed that the concentration of Pb-210 in Chinese tobacco ranged from 0.0289 to 0.0566 Bq/g at an average of 0.0419 Bq/g. The concentration of Po-210 in Chinese tobacco ranged from 0.0155 to 0.0568 Bq/g at an average of 0.0349 Bq/g. The concentrations of Pb-210 and Po-210 in Chinese tobacco are rather higher than that of Japanese and other countries.
