Abstract

The polonium-210 in the sea and its radiological consequences have been widely studied. Current processes for ²¹⁰Po recovery from seawater vary significantly. We compared selected processes to determine optimal conditions for recovery in modestly equipped laboratories. Plating ²¹⁰Po onto a Ag planchet with constant stirring for 15h at room temperature after preconcentration from seawater samples with Mn was preferred, achieving more than 96% recovery with 3% or less precision. Possible contaminants were masked only by ascorbic acid treatment.
