Natural levels of polonium-210 in urine
Journal of Radiological Protection, 2018Abstract This paper presents a review and analysis of available data on background levels of polonium-210 in urine. It was established that 819 measurements could be considered to correspond to natural background levels, excluding a large number of values identified by the original investigators as potentially due

Investigation of the decay of polonium-210
Il Nuovo Cimento, 1958Conversion coefficient of 800 keV γ-rays from the decay of Polonium-210 has been measured using scintillation method to be 0.039 ± 0.01. The value of conversion coefficient has also been obtained by the measurement of conversion electrons with an end window type G.M. counter.

Effects of Polonium-210 on Mouse Ovaries
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1966SummaryFemale mice were injected intraperitoneally with polonium-210 and the localization in ovary and uterus and effects on oocyte survival were studied. Radioautographic studies showed that polonium-210 was localized primarily in the follicle cells of the ovary, whereas it was distributed diffusely through the myometrium of the uterus.

Lead-210 and Polonium-210 in Grass
Nature, 1960Evidence 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 ...

Source of Lead-210 and Polonium-210 in Tobacco
Science, 1966Test plants were grown within a chamber enriched with radon-222 in the atmosphere, in tobacco fields with different sources of phosphate-containing fertilizer, and in culture containing lead-210 in the nutrient solution. Harvested leaves were subjected to three curing conditions.

Polonium-210 levels in different environmental samples
Environmental Science and Pollution Research, 2015Polonium-210 is analysed in different samples which can be affected by the presence of a dicalcium phosphate plant (DCP). Particularly, it was determined in sludge samples from a drinking water treatment plant located downstream of the phosphate plant.

Kidney Disease in Beagles Injected with Polonium-210
Radiation Research, 1990An unusually high incidence of kidney disease (tubular degeneration and necrosis with fibrous replacement) was observed among 24 beagles injected at about 5 years of age with 116 or 329 kBq 226Ra kg-1 but not among an additional 10 beagles given about 39 kBq 226Ra kg-1. This 226Ra solution also contained 210Pb, 210Bi, and 210Po.

Polonium-210 in Bronchial Epithelium of Cigarette Smokers
Science, 1967Analyses of smokers pulmonary tissues that showed "hot spots" of 210-polonium at segmental bifurcations of bronchial epithelium (4.5 pc/g of wet tissue vs. .12 in the trachea 119 in the lobar bronchi and .004 in the bronchial wall and submucosa) are 100 times higher than some recently reported radiation dose estimates for these areas.
