Abstract

A straightforward and rapid method has been developed for the determination of 241Pu activities Pu is chemically separated from the sample purified and electrodeposited to produce a source for alpha spectrometric determination of 238Pu and 239240Pu Pu is stripped from the disc with concentrated nitric acid and extracted into trioctylphosphine oxide TOPO/toluene The organic extract is then mixed directly with commercial liquid scintillation cocktail without any further purification procedures and the sample counted on a Wallac 1220 Quantulus liquid scintillation counter LSC 241Pu activity is estimated via the 242Pu yield monitor acquired by alpha spectrometry measurement Experimental results for the performance testing of a lowlevel liquid scintillation spectrometer and the data for the evaluation of the method using standard reference materials are presented
