The part played by polonium-210 in contributing to the biologically effective radiation dose received by humans in a variety of environments is described. The selection of data presented has been dictated to a large extent by the availability of post-mortem and other specimens and cannot be considered comprehensive. 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… 
Measurement of Polonium-210 in Human Blood
It is found that polonium-210 can be easily detected in human blood samples by a simple radiochemical and counting technique and may be a practical method of estimating body burdens of this isotope, as well as of its parent lead-2102.
Absorption of environmental polonium-210 by the human gut
The results appear to suggest that the gut absorption factor in current use for 210Po (in connection with ingestion in food) should be increased from 0.1-0.3 to about 0.8.
Polonium-210 as a poison
An evaluation of published human and animal data and models developed for the estimation of alpha radiation doses from 210Po and the induction of potentially fatal damage to different organs and tissues suggests that bone marrow failure is likely to be an important component of multiple contributory causes of death occurring within a few weeks of an intake by ingestion.
Radionuclides in selected human tissues.
Compared to the values used in computing maximum permissible concentrations for radiation workers, it would appear that considerably more effort is required on the determination of the body distribution of the more common radionuclides being ingested by the population today.
The binding of polonium-210 to rat tissues.
The subcellular distribution of 210Po has been studied over periods of up to 47 days after intravenous, oral or intramuscular injection of the nuclide as citrate or in colloidal form, suggesting that lipids may be involved in the 21OPo complex in vivo, but no direct evidence for polonium-lipid complexes was found.

This paper is the result of assembling and interpreting existing Po-210 data within the context of what is considered a reliable risk model (hazard-function [HF] model) for characterizing the risk of death from deterministic effects of high alpha radiation doses and dose rates to body organs.
Natural α-Radioactivity Concentrations in Bone and Liver from Various Animal Species
The preliminary results of a comparative interspecies study on total alpha-activities in bone ash from about a dozen different animal species are reported.
Cesium-137, lead-210 and polonium-210 concentrations in selected human tissues in the United States.
Of the tissues tested, the 210Po/210Pb ratio for the liver and lung showed ratios consistently greater than one, while the ratios for the other tissues were usually found to be less than one.

Polonium-210 in Marine Plankton
The concentrations of polonium-210 and lead-210 in foodstuffs, tobaccos and human tissues from various environments are discussed, and additional data have been provided by Hill, Holtzmami6, Little and McGandy7 and others.


Lead-210 and Polonium-210 in Human Tissues
The results of preliminary radiochemical estimations of polonium-210 and lead-210 in human bone and soft tissue samples are described, which suggest that these nuclides may occur in certain human foodstuffs through inhalation and ingestion.
Lead-210 and Polonium-210 in Grass

Evidence is presented that suggests that a large part of the alpha activity observed in certain samples of grass may originate as a decay product of atmospheric radon which is deposited onto the

The methods are applied to the analysis of experimental animals exposed to natural levels of radon and its short-lived daughters, yielding a natural Po whole body content of about 5 x 10-15 c/g.
Radiogeology and Population Exposure to Background Radiation in Northern New England.
Results of the survey showed no significant relationship between equivalent uranium concentration and the level of Ra/sup 226/ and Po/sup 210/ in teeth, and dosimetric evaluation of population exposure revealed relatively small differences with respect to external gamma radiation.
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.
Measurement of the natural contents of RaD (Pb210) and RaF (Po210) in human bone--estimates of whole-body burdens.
The natural RaD (Pb210) concentration in man was determined from measurement of the RaF (Po210) in bone samples obtained from surgery and autopsy of unexposed individuals, mostly from Illinois. About
High Effectiveness of Chronic Neutron Exposures for the Induction of Specific Locus Mutations in Mice
An experiment of this type, using the specific locus method, is now in progress and has revealed a surprisingly high yield of mutations following fast neutron irradiation of mouse spermatogonia.
Ultimate Maximum Values of the RBE of Fast Neutrons and Gamma-rays for Chromosome Aberrations
SummaryIf for some radiobiological effect the form of the dose-response is different for two radiations, the value of the RBE will vary with the dose, and a single value at just one level of effect

THE mean linear energy transfers of 650-keV neutrons and of 250-kVp X-rays are so markedly different that it is not usually possible to establish a unique value for their relative biological
Natural Lead-210 Content of Man
The natural Pb2l0 content of ash samples from 18 cadavers has been measured, and an average in vivo content of 0.0 15 picocurie per gram of wet bone is estimated. The contribution of Pb210 to the
