}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 grass by rainfall. Results are reported from measurements of alpha activity of samples of grass and soil collected in the southern part of Great Britain. Measurements were also made on tissues from lambs from the same region. Polonium-210 was found concentrated in the kidney. Observations of the decay…

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.
Natural Levels of Lead-210, Polonium-210 And Radium-226 in Humans and Biota of the Arctic

High levels of fall-out suggest, together with the proposed mechanism of uptake and the similarities to strontium-90 in atmospheric distribution and biochemistry, that in Arctic biota, the naturally occurring airborne nuclides lead-210 and its decay product, polonium-210, may also be present in high concentration.
Lead-210 in Natural Waters

The distribution of lead-210 which enters the oceans subsequent to its production in the atmosphere by radon-222 decay, shows an increase with depth in sea water, and it is suggested that the marine biosphere is responsible for the conveyance of lead from surface to deeper waters.

It is feasible to view the occurrence of lead-210 as a “natural fall- out” product, similar, in this respect, to fission product fall-out, artificially produced from a nuclear detonation.

Polonium-210, which emits alpha particles, is a natural contaminant of tobacco and may be significant in the genesis of bronchial cancer in smokers.

The Radford and Hunt2 group maintained that polonium is more dangerous because of its volatility above 500° C, and estimated the radiation dose to bronchial epithelium from 210Po inhaled in cigarette smoke to be at least seven times that from background sources, and in localized areas possibly up to 200 times.

Interest has recently been largely concentrated on man-made activity, particularly the β emission of such substances as strontium 90, but knowledge of the radioactivity of their environment is so scanty that it seems possible that a number of sources of irradiation of human beings may exist of which the authors are at the moment completely ignorant.
