Pre-concentration of naturally occurring radionuclides and the determination of 212Pb from fresh waters

A novel technique has been developed for determining the 212Pb activity of fresh waters. This is of interest to environmental monitoring programmes that utilise gross α-activity methods to screen for anthropogenic radionuclides. The contribution from 212Pb varies, and is difficult to experimentally...

Description
Summary:A novel technique has been developed for determining the 212Pb activity of fresh waters. This is of interest to environmental monitoring programmes that utilise gross α-activity methods to screen for anthropogenic radionuclides. The contribution from 212Pb varies, and is difficult to experimentally measure due to its relatively short half-life ( t ½ = 10.6 h) and low environmental activity (
