Abstract

A new rapid separation method for radiostrontium in emergency milk samples was developed at the Savannah River Site (SRS) Environmental Bioassay Laboratory (Aiken, SC, USA) that will allow rapid separation and measurement of radiostrontium within 8 hours. The new method uses calcium phosphate precipitation, nitric acid dissolution of the precipitate to coagulate residual fat/proteins and a rapid strontium separation using Sr Resin (Eichrom Technologies, Darien, IL, USA) with vacuum-assisted flow rates. The method is much faster than the previous method that use calcination or cation-exchange pretreatment, has excellent chemical recovery, and effectively removes beta-interferences. When a 100 mL sample aliquot is used with a 20 minute count time, the method has a detection limit of 0.5 Bq·L−1, well below generic emergency action levels.
