Abstract
- Liquid scintillation counting (LSC) is an easy and straightforward technique, and combined with its low limit of detection, makes it a powerful tool for both routine and low level measurements that can be applied to <superscript>210</superscript>Pb low level counting in environmental samples. <superscript>210</superscript>Pb can be easily measured following a sulphate co-precipitation method; the addition of a carrier and the weighing of the recovered amount is a widespread technique to evaluate radiochemical yield, however, this evaluation of the recovery is sometimes questioned. The samples employed in this work were recollected in 1999 and 2005 from the estuary of the Odiel and Tinto rivers (SW of Spain), which were affected by phosphogypsum (pg.) discharges until 1998. Phosphogypsum contains most of the <superscript>210</superscript>Pb from the treated raw material, for that reason analysed riverbed sediments have enhanced <superscript>210</superscript>Pb activity concentrations and hence, enhanced activity concentration of its daughter <superscript>210</superscript>Po, both in secular equilibrium after two years.
