Abstract  

A radiochemical separation procedure has been developed for a very efficient isolation of plutonium from environmental samples. Essentially, the method involves the following steps: ashing of the sample and preparation of the load solution; separation of plutonium by a column containing a commercially available, highly specific, supported extractant; electrodeposition of Pu and subsequent -spectrometry. Detailed procedures are reported for liver samples and for soil. The modifications necessary for sample sizes above 5 g dry weight and up to 200 g are also given. Recoveries of added tracers are 60–70%. The precision of the method is <10% (RSD). The accuracy was examined by analyzing also certified standard reference materials. Due to the very efficient isolation of Pu, the resulting -spectrum is virtually free of interfering -emitters of Th and U.
