Abstract
An improved method for the determination of plutonium in the environme nt was developed, in which TOPO extraction and a parallel grid ionizat ion Chamber alpha-spectrometer are used to determine Pu-239+240 and Pu -238 in soil and grass. The chemical recoveries are 72% and 97%, respe ctively. Good agreement is obtained with the analysis of reference mat erials from IAEA and NIST. The detection limit of the procedure is 4 10(-2) Bq/kg. It is a simple and rapid method for environmental measu rements suitable for emergency analysis in the case of a nuclear accid ent.
