210Pb Studies in Beagles

Health Physics, 1975
AbstractCarrier-free 210Pb was administered intravenously to 10 young adult beagles in a sodium citrate citric acid solution (pH 3.5). Retention was determined by total-body counting of the 47-keV gamma-ray.

Standardisation of 210Pb

Applied Radiation and Isotopes, 2000
The standardisation of 210Pb is complicated by the presence of the daughters, 210Bi and 210Po. In addition, the low energies of the beta emissions from 210Pb make it difficult to obtain high detection efficiencies in an atmospheric proportional counter and hence produce the need for large extrapolations with consequential large uncertainties when ...

210Pb/210Po isotope generator

Journal of Radioanalytical and Nuclear Chemistry, 2018
As a continuation of previous work (Kmak et al. in J Radioanal Nucl Chem 314:985–989, 2017), an isotope generator column based on the 210Pb decay chain has been made to produce highly radiopure 210Po. Two replicate studies were performed on AG 50Wx8 columns with an average yield of 90.4 ± 1.9%.

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.

210Pb in Bioenergy Production

Radiation Protection Dosimetry, 1988
Abstract 210Pb is probably one of the major contributors to the radiation dose received by humans from the fumes emitted from the stacks of power plants using fossil fuels or biofuels. As a first step in the estimation of the total radiological impact on humans of radioactive emissions, we have determined 210Pb radioactivity enrichment ...
