Radioactivity of tobacco trichomes and insoluble cigarette smoke particles

  title={Radioactivity of tobacco trichomes and insoluble cigarette smoke particles},
  author={Edward A. Martell},
Airborne 210Pb is concentrated on small Aitken particles which accumulate on tobacco trichomes. Tobacco curing and the combustion of trichomes in burning cigarettes produce insoluble particles of high 210Pb radioactivity which are inhaled and deposited in the bronchi of smokers. The subsequent ingrowth of 210Po results in high local a irradiation which may account for bronchial cancer among smokers. 
Aerosol particles on tobacco trichomes
Evidence is provided for one of the steps in the sequence by which atmospheric radioactivity is incorporated into insoluble particles that are deposited in the lungs of tobacco smokers.
Polonium-210 in cigarette tobacco
Cigarette smokers who consume one pack (20 cigarettes) per day are inhaling an average of 151 mBq/day of 210Po and 210Pb each, and the mean values of the annual effective dose for smokers were estimated to be 237 and 309 µSv, respectively.

Determination of polonium-210 in cigarettes from Syria
Various Syrian cigarettes /Hamra long filter, Oreidt, Granata, Palmyra, Hamra short filter/ were analyzed for their210Po content.210Po was precipitated on a silver plate after chemical separation and
Polonium and Lung Cancer
Various studies have confirmed that the radiological risk from Po-210 in a smoker of 20 cigarettes per day for a year is equivalent to the one deriving from 300 chest X-rays, with an autonomous oncogenic capability of 4 lung cancers per 10000 smokers.

Cigarette smoking in China is the world’s largest producer and consumer of cigarettes, yet no comprehensive published reports of the 210Pb and 210Po activity concentrations in Chinese cigarettes are available, and it is estimated that a person smoking 20 of these cigarettes per day in China would inhale a mean (range) of 37 (29–46) mBq d−1 of 210P b and 60 (47–75) m Bq d −1 of210Po.

Polonium-210: A Volatile Radioelement in Cigarettes
Polonium-210, which emits alpha particles, is a natural contaminant of tobacco and may be significant in the genesis of bronchial cancer in smokers.
Lead-210 and Polonium-210 in Tissues of Cigarette Smokers
Concentrations of lead-210 and polonium-210 in rib bones taken from 13 cigarette smokers were about twice those in six nonsmokers, the polonium-210 being close to radioactive equilibrium with the
Polonium-210 Content of Mainstream Cigarette Smoke
When eleven brands of cigarettes were smoked in a standardized manner, differences in the polonium-210 content of various brands were found, related to the amount of particulate matter in the mainstream smoke.
Polonium-210 in Bronchial Epithelium of Cigarette Smokers
Analyses of smokers pulmonary tissues that showed "hot spots" of 210-polonium at segmental bifurcations of bronchial epithelium are compatible when the type and quality of tissues used are taken into consideration.
Distribution of polonium-210 in pulmonary tissues of cigarette smokers.
The patterns of distribution of polonium throughout the lung suggest that most inhaled smoke particles are rapidly cleared from the lung, andPolonium is primarily cleared by mucus sheet, which may be implicated in the initiation of bronchial cancer in humans.
Source of Lead-210 and Polonium-210 in Tobacco
Test plants were grown within a chamber enriched with radon-222 in the atmosphere, in tobacco fields with different sources of phosphate-containing fertilizer, and in culture containing lead-210 in the nutrient solution to study the effect of stage of leaf development and methods used to cure the leaf on the final amount of polonium-210.
Concentrations of 210Pb and 210Po in human soft tissues.
Concentrations of 210Pb and 210Po in tissues from twenty individuals are reported and the two highest average 210Po concentrations were 14.5 and 11.3 pCi/kg in liver and kidney, respectively.
Asbestos exposure, smoking, and neoplasia.
It is concluded that asbestos exposure should be minimized, that asbestos workers who do not smoke should never start, and that those now smoking should stop immediately.

The correspondence both for grazing animals and humans between the levels of polonium-210 in the food of a community and in the tissues of its members clearly indicates that food ingestion is an important route for acquisition of body-burdens of the nuclide.
