Polonium-210 and lead-210 in food and tobacco products: a review of parameters and an estimate of potential exposure and dose

  title={Polonium-210 and lead-210 in food and tobacco products: a review of parameters and an estimate of potential exposure and dose},
  author={Annetta P. Watson},
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.
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
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
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.
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


Review of parameters describing terrestrial food-chain transport of lead-210 and radium-226
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
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
Lead-210 Content in Foodstuff and its Dietary Intake in Japan
The largest contributor to the total dietary intake of 210Pb would be sea foods which have relatively high concentration of the nuclide and are being consumed to a considerable extent in this country. Expand
Transfer of 226Ra, 210Pb and uranium from soil to garden produce: assessment of risk.
: A study of gardens contaminated by uranium processing wastes was carried out in the town of Port Hope, Ontario, during the summer of 1976. Concentrations of 226Ra, 210Pb, and total uranium wereExpand
Implication of the transfer of trace metals from sewage sludge to man
Twenty five trace elements have been detected in sewage sludges, and of these lead and cadmium content are of particular importance in relation to the extent to which they may constitute a hazard toExpand
Lead-210 in tobacco and cigarette smoke.
A study of the levels of other radionuclides, specifically lead-210 in cigarette smoke, was undertaken at the Northeastern Radiological Health Laboratory, Public Health Service to ascertain if further insult to the lungs occurs. Expand
Polonium 210 in tobacco, cigarette smoke, and selected human organs.
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
Metabolic balances of $sup 210$Pb and $sup 210$Po in unexposed men
From 3rd international congress of the International Radiation Protection Association meeting; Washington, District of Columbia, USA (9 Sep 1973). The metabolic balances of naturally occurring /supExpand
Transfer factors for assessing the dose from radionuclides in agricultural products
Transfer factors to predict the environmental transport of radionuclides through terrestrial foodchains to man were derived from the literature for radionuclides associated with the nuclear fuelExpand
Lead-210 in air and total diets in the United States during 1966.
Abstract Data are presented on the concentrations of lead-210 in air and diet samples collected from various geographical locations in the United States during 1966. The average lead-210Expand
