Food-chain transport of Pb-210 and Po-210 from soil to edible plant parts and from animal feed to meat and milk were evaluated from a review of literature. The degree of transfer was characterized by estimating concentration factors (unweighted arithmetic means) as well as the transfer coefficients Bv, Br (unweighted geometric means), fm and ff (unweighted arithmetic means). Global dietary intake of Pb-210 and Po-210 was also summarized, and 50-year dose estimates to target organs calculated… Expand
Concentration levels of 210Pb and 210Po in dry tobacco leaves in Greece.
TLDR
In the present study, the concentrations of these two radionuclides were determined in tobacco samples from seven regions in Greece and the mean value of the annual committed effective dose for smokers (20 cigarettes per day) of Greek tobacco was estimated to be 287 microSv. Expand
Activity concentrations of 232Th, 226Ra and 40K and gamma radiation absorbed dose rate levels in farm soil for the production of different brands of cigarette tobacco smoked in Nigeria
TLDR
In this study, soil samples from three farmlands used for the production of the tobacco leaves were collected in order to determine the activity concentrations of 226Ra, 232Th and 40K in the farm soil, which were found to be higher than world average values while those of the control farm values were lower to world averages and the tobacco leaf farms.

Comprehensive survey of radionuclides in contemporary smokeless tobacco products
TLDR
Results indicate that, among 34 Swedish snus and 44 US STPs, a more complex radionuclide content exists than previously reported for these products, and 40K in particular may expose the oral cavities of STP users to β-radiation. Expand
Transfer factors of polonium from soil to parsley and mint.
TLDR
The results have shown that there was a clear uptake of (208)Po by roots to leaves and stems of both plants, and about 75% of Po was transferred from atmosphere to parsley parts using the two systems. Expand
Review of Russian language studies on radionuclide behaviour in agricultural animals: 3. Transfer to muscle.
Over 150 publications reporting studies conducted in the former USSR were reviewed to provide transfer coefficients (F(f)) to the muscle of domestic animals from experiments using chronicExpand
A study on 210Pb and 210Po levels in different tobacco types produced in Turkey and the estimation of the committed effective dose
In this study, 210Pb and 210Po activity concentrations in tobacco samples produced in 12 different regions of Turkey have been investigated and the estimation of the annual committed effective dosesExpand

Because of the technological enhancement and environmental persistence of naturally occurring /sup 210/Pb and /sup 226/Ra, food-chain transport of these nuclides is important to the evaluation ofExpand
Polonium-210 in Man
TLDR
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. Expand
