Determination Of Lead-210 And Polonium-210 In Marine Environment [PDF]

, 2009
Naturally occurring 210 Pb and 210 Po are important tracers used in marine environment studies. In this study, 210 Po and 210 Pb measurements in marine samples (sediment, sea water and biota) were performed using alpha spectrometry. Chemical recoveries are obtained using 209 Po tracer.

Source of Lead-210 and Polonium-210 in Tobacco

Science, 1966
Test 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.

Sequential and rapid determination of Po-210, Bi-210 and Pb-210 in natural waters

Talanta, 1994
A sequential and rapid separation method for the determination of radon daughter nuclides, Pb-210, Bi-210 and Po-210 has been developed for application to natural waters. Rapid separation is attained by the use of the same hydrochloric acid solution.

The ratio of lead-210 to polonium-210 in U.K. diet

Science of The Total Environment, 1986
The levels of the natural radionuclides, 210Pb and 210Po, in U.K. diet have been measured previously. However, in the earlier measurements, the samples were sufficiently aged for 210Pb and 210Po to have attained secular equilibrium. In order to determine the extent of disequilibrium between these radionuclides in fresh food, measurements have been made

Lead-210 and Polonium-210 in Tissues of Cigarette Smokers

Journal of Occupational and Environmental Medicine, 1966
Concentrations of lead-210 and polonium-210 in rib bones taken from 13 cigarette smokers were about twice those in six nonsmokers, the polonium-210 being close to radioactive equilibrium with the lead-210. In alveolar lung tissue the concentration of lead-210 in smokers was about twice that in nonsmokers.

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 ...

Polonium-210 and lead-210 in the marine environment

Geochimica et Cosmochimica Acta, 1970
Abstract A method is outlined for the determination of lead-210 and polonium-210 in sea water by solvent extraction, followed by electrodeposition and alpha counting. Data are given for the lead-210 and polonium-210 content of twenty nine samples collected at a depth of 20 m in the sea around the Cape of Good Hope during March 1969.

Polonium-210 as a poison

Journal of Radiological Protection, 2007
The death of Alexander Litvinenko on 23 November 2006 has brought into focus scientific judgements concerning the radiotoxicity of polonium-210 ((210)Po). This paper does not consider the specific radiological circumstances surrounding the tragic death of Mr Litvinenko; rather, it provides an evaluation of published human and animal data and models ...
