Determination of plutonium in urine by radiochemical separation and use of etched CR-39 track analysis.
Well-validated preparative and radiochemical procedures for separating plutonium from urine by wet-oxidation, ion-exchange and electrodeposition are outlined. Recently developed application of etched alpha track analysis using an automated image analyser is described. Experiences with this sensitive radiometric technique are reported and discussed.
