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...
متن کاملPossibility of wine dating using the natural Pb-210 radioactive isotope.
To control the authenticity of an old wine without opening the bottle, we developed a few years ago a method based on the measurement of the (137)Cs activity. However, for recent vintages, the (137)Cs activity drops to far too low values (most of the time less than 10 mBq/L for a 10-year-old wine) for this method to perform correctly. In this paper we examine the possibility to date wines using...
متن کاملPo 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 ...
متن کاملUse of lead-210 as a novel tracer for lead (Pb) sources in plants
Lead (Pb) released from anthropogenic sources and stored in environmental repositories can be a potential source for secondary pollution. Here we develop a novel approach for tracking Pb from atmospheric deposition and other sources in the environment using fallout (210)Pb as a tracer, and apply the method to samples collected from Richmond Park, London, the UK. The mean ratio of (210)Pb to tot...
متن کامل-Ray Spectrometric and a -Counting Method Comparison for the Determination of Pb-210 in Estuarine Sediments
An intercomparison of methodology and of dating results, from a counting and from the more recent g -spectrometry method, has been made for marine sediment cores from several locations. The former method involves considerable chem ical manipulation, whereas the latter is more straightforward and enables direct interpretation of the results. Similar precisions ( ; 12%) were found for both method...
