Lead-210 and Polonium-210 in Grass

Nature, 1960
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 ...

Lead-210 and Polonium-210 in Human Tissues [PDF]

Nature, 1963
IT has recently been shown1 that appreciable amounts of lead-210 and polonium-210 may occur in certain human foodstuffs as a result of deposition from the atmosphere of long-lived radon decay-products (Table 1). Absorption of these products may therefore occur by both inhalation and ingestion, but, although measurements of the activity of lead-210 in ...

Lead and Lead-210 in Rainwater

Nature, 1967
THERE is a continuing interest in the possible toxicity to man and animals from the present and future concentrations of lead in the environment. The importance of environmental lead was emphasized by Monier-Williams in 1938 (ref. 1), and has since resulted in numerous studies2–4.

Lead-210 in Natural Waters

Science, 1961
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. By use of a simplified two-layer model of the ocean, a residence time of lead in the upper mixed layer of less than 2 years is derived.
