Determination of 134Cs and 137Cs in milk by sorption on freshly prepared precipitate of Cu(II) hexacyanoferrate in combination with gamma spectrometry

Abstract

A simple and rapid method for the determination of 134Cs and 137Cs in cow's milk has been worked out. The method is based on the separation of radiocaesium from milk by sorption on a freshly prepared precipitate of Cu(II) hexacyanoferrate, on the separation of the precipitate by centrifugation, and on the gamma-spectrometric measurement of the precipitate activity.
