    A NEW WAY FOR DETERMINATION OF PLUTONIUM IN THE ENVIRONMENT

    • A new way for the determination of plutonium in environment is provided, in which TOPO extraction with parallel grid ionization chamber spectrometer is used to determine 239,240pu and 238Pu in soil and grass ash. The chemical recoveries for them are 72% and 97% respectively. The good agreement is obtained for analysis of standard reference materials of IAEA and NIST. The detection limit of this method is 4×10-2Bq/kg(solid). It is a simple and quick method for environment monitor and emergency nuclear accident analysis.
