Polonium-210, which emits alpha particles, is a natural contaminant of tobacco. For an individual smoking two packages of cigarettes a day, the radiation dose to bronchial epithelium from Po210 inhaled in cigarette smoke probably is at least seven times that from background sources, and in localized areas may be up to 1000 rem or more in 25 years. Radiation from this source may, therefore, be significant in the genesis of bronchial cancer in smokers. 
Polonium in Cigarettes—Spectroscopic Analysis
ALPHA-RADIOACTIVITY in cigarettes has recently been measured by two groups. Turner and Radley1 suggested that 210Pb and 210Po are not present in the raw tobacco at levels of activity of the sameExpand
POLONIUM-210 IN ITALIAN TOBACCO
Abstract It is known that 210Po contained in tobacco is volatile at the temperature of a burning cigarette. Hence a radiation hazard from 210Po may arise for a smoker's bronchial epithelium. HenceExpand
Study of Polonium-210 in Persian Cigarette and Tobacco Crops.
TLDR
Drying in direct contact with fumes of fossil fuel seems like one of the main excessive sources of 210Po in Persian cigarettes. Expand
Systemic absorption of polonium-210 inhaled in cigarette smoke.
TLDR
The kinetics of the change in the concentration of polonium-210 in the peripheral blood of six cigarette smokers has been studied and indicates that a major fraction of the Isotope inhaled in cigarette smoke is absorbed directly into the blood stream. Expand
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 theExpand
Polonium-210 in cigarette tobacco
TLDR
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. Expand
Polonium-210 Activity in the Lungs of Cigarette Smokers
TLDR
The lung tissue dissected from heavy smokers was shown to contain 3-4 times the 210Po activity found in the lungs of nonsmokers, and the parenchymal tissue the bifurcation and the bronchial tissue were dissected before measurement. Expand

TLDR
The results of this work indicate that the average (range) activity concentration of (210)Po in cigarette tobacco was 16.6 (9.7-22.5) mBq/cigarette, which might contribute significantly to an increase in the internal radiation dose and in the number of instances of lung cancer observed among smokers.

Polonium 210 in tobacco, cigarette smoke, and selected human organs.
TLDR
Since Polonium 210 may be one of the causes of lung cancer a study was undertaken to determine its level in filtered and nonfiltered cigarettes, and tests indicated higher levels of polonium210 in the organs of smokers. Expand
Natural radioactive nuclides in cigarettes and dose estimation for smokers
TLDR
The annual effective dose of radionuclides to smokers was found to be 0.27 mSv year−1, which was lower than an intervention exemption level given in International Commission on Radiological Protection (ICRP Publ. 82). Expand

TLDR
The present report represents an evaluation of the contributions that laboratory research is making in this field and concludes that the importance of laboratory work is not to prove that smoking is a cause of cancer in man. Expand
