Double tracer studies to optimize conditions for the radiochemical separation of plutonium from large volume sea water samples
From meeting on reference methods for marine radioactivity studies: determination of transuranic elements, radioruthenium, and other radionuclides in marine environmental samples''; Vienna, Austria (30 Oct 1972). A procedure for optimizing conditions for the radiochemical separation of plutonium from seawater is described in which /sup 242/Pu is added to determine the overall recovery of Pu separated from the sample and the recovery of /sup 242/Pu at any chosen point in the procedure is measured by the addition of a similar amount of /sup 236/Pu at that point and the percentage of /sup 236/Pu finally recovered is used to calculate the /sup 242/Pu recovery at the time of /sup 236/Pu additio n. The experience gleaned from this double tracer experiment has permitted improvement in the ability to recover plutonium from 50 l seawater samples for alpha spectrometric analysis of /sup 239/240/Pu and, in some cases, /sup 238/Pu.
