Radiochemical determination of lead-210 in environmental water samples using Cerenkov counting

A procedure is described which involved separating the lead-210 as lead sulphate from interfering elements, dissolving the lead sulphate in alkaline EDTA and counting after one month using the tritium channel of a liquid scintillation counter. The procedure involved determining lead-210 via its beta...

Description
Summary:A procedure is described which involved separating the lead-210 as lead sulphate from interfering elements, dissolving the lead sulphate in alkaline EDTA and counting after one month using the tritium channel of a liquid scintillation counter. The procedure involved determining lead-210 via its beta-emitting bismuth-210 daughter. The lower limit of detection for lead-210 using a 500 minute counting period was 5.10 mBq per litre. The procedure could be used for drinking water and any other type of sample that could be prepared as an aqueous solution.
