Rapid analysis of americium and plutonium in environmental samples by alpha-spectrometry

Abstract

A new method to assay americium and plutonium in soil samples is reported here. Using the method, it is possible to have a uniform and thin layer of the sample on alpha-spectrometer disc by electroplating. Prior to electrodeposition, the sample is separated by short column chromatography. A current of 900 mA and a plating time of 90 min in the pH range 2�2.5 have been found to be the best conditions for the deposition of americium. Optimum conditions for separation and electrodeposition of plutonium from soil samples have also been obtained. The modified procedures have been successfully applied for the simultaneous determination of Am and Pu
