Abstract
An accurate and reliable method has been developed for the sequential determination of241Am and plutonium in miscellaneous environmental and biological samples. In the course of the analysis,244Cm and236Pu tracers were used for the determination of chemical recoveries. After suitable pretreatment procedures, plutonium and americium were separated by means of anion exchange and the separate nuclides were electroplated onto stainless steel discs and determined by alpha sepectrometry. The final recovery ranged from 70.7 to 99.4% for plutonium and from 75.4 to 91.9% for americium and curium with 50 g of soil samples. No interference of210Po was detected.
