A study on the excretion of Pb-210 and Po-210.

Bioaccumulation of 210 Po and 210 Pb in Arctic seabirds

INTRODUCTION When considering the potential radiological impacts of anthropogenic radionuclides in the environment, it is important to understand the doses incurred by biota by natural activity concentrations of naturally occurring radionuclides. Naturally occurring Po (half-life138 days) and Pb (half-life 22.3 years) are members of the U decay chain. In the marine environment, Po and Pb are pr...

Po and 210 Pb in the Terrestrial Environment Bertil

The natural sources of 210Po and 210Pb in the terrestrial environment are from atmospheric deposition, soil and ground water. The uptake of radionuclides from soil to plant given as the soil transfer factor, varies widely between various types of crops with an average about 0.056±0.003. The atmospheric deposition of 210Pb and 210Po also affect the activity concentrations in leafy plants with a ...

Assessment of 210 Po in Italian diet

Biliary excretion of 203 Hg, 64 Cu, 52 Mn, and 210 Pb in the rat.

(210)Po and (210)Pb in the tissues of the deep-sea hydrothermal vent mussel Bathymodiolus azoricus from the Menez Gwen field (Mid-Atlantic Ridge).

The hydrothermal deep-sea vent fauna is naturally exposed to a highly specific environment enriched in potentially toxic species such as sulfides, metals and natural radionuclides due to the convective seawater circulation inside the oceanic crust and its interaction with basaltic or ultramafic host rocks. However, data on radionuclides in biota from such environment are very limited. An invest...
