Metabolism of 210Po in rats: volatile 210Po in excreta

Radiation Protection Dosimetry, 2010
Polonium-210 ((210)Po) is one of the most toxic radionuclides and was used as a poison in the Alexander Litvinenko case. In this study of the metabolism of (210)Po in rats, volatile (210)Po in excreta was measured, filling a knowledge gap of the previous studies. Five rats were intravenously administrated with 2 kBq and another five with 10 kBq of (210)

Metabolism of 210Po in rats: volatile 210Po from faeces

Radiation Protection Dosimetry, 2010
The metabolic formation of volatile (210)Po species in a rat that was intravenously administered with (210)Po-citrate was investigated in this study. A slurry of the faecal sample was prepared in water and was bubbled with nitrogen gas in a closed system.

Aspects on the analysis of 210Po

Journal of Environmental Radioactivity, 2011
There has been little development regarding analysis of polonium (Po) in environmental samples since the 1960 ies. This is due to the straightforward spontaneous deposition of this element on silver (Ag), nickel (Ni) or copper (Cu) without any radiochemical separation.

Fission of 210Po

Nuclear Physics A, 1970
Abstract The excitation functions of the reactions 206Pb(α, f) and 209Bi(p, f) and the anisotropy parameters characterizing, at various excitation energies, the angular distributions of fragments emitted in both reactions are analysed. In the analysis of the excitation functions the angular momentum of the fissioning nucleus is explicitly taken into ...

210Pb and 210Po in Finnish cereals

Journal of Environmental Radioactivity, 2011
A survey was carried out on the activity concentrations of (210)Pb and (210)Po in cereal grains produced in Finland. The cereal species were wheat (Triticum aestivum), rye (Secale cereale), oats (Avena sativa) and barley (Hordeum vulgare), which account for 90% of the Finnish consumption of cereal products.

Determination of 210Po and 210Pb in rainwater using measurement of 210Po and 210Bi

Analytica Chimica Acta, 2000
Abstract A method for determination of 210 Po and 210 Pb in rainwater samples is described. This method was developed to permit measurement of the radionuclides in rainwater samples collected at short time intervals (2 weeks) on a small area (0.5 m 2 ) and to give results with the minimum delay. This was achieved by estimating

210Po bioaccumulation by mushrooms from Poland

Journal of Environmental Monitoring, 2003
The paper presents results on 210Po activity concentration measured in mushroom samples collected in northern Poland (Białogard and Elblag areas). Among 20 species of wild mushrooms, King Bolete (Boletus edulis), accumulated 210Po in the highest degree.

Bioaccumulation of polonium 210Po in marine birds

Journal of Environmental Radioactivity, 2007
The aim of this work was to determine the 210Po content in marine birds which permanently or temporally live in the Polish part of the Baltic Sea. We chose 11 species of sea birds: three species permanently residing at southern Baltic Sea, four species of wintering birds and three species of migrating birds.

210Po AND 210Pb ACTIVITY IN CHINESE CIGARETTES

Health Physics, 2009
The radon decay products lead-210 ((210)Pb) and polonium-210 ((210)Po) are known components of tobacco. China is the world's largest producer and consumer of cigarettes, yet no comprehensive published reports of the (210)Pb and (210)Po activity concentrations in Chinese cigarettes are available.

210Po and 210Pb variations in fish species from the Aegean Sea and the contribution of 210Po to the radiation dose

Marine Pollution Bulletin, 2012
In recent years, there has been increasing interest in the significance of natural radionuclides, particularly (210)Po, in the marine environment. (210)Po, a naturally occurring alpha emitter, accumulates in marine organisms and reflects differences in their diets.
