analysis of all detectable radionuclides, VI. RADTOCHEMICAL ANALYSES Required analytical measurements on samples recovered in the survey of Eniwetok Atoll are summarized in this document. The information is presented in tabular form, beginning with a description of various sample types and estimated quantities to be recovered, In Table II we summarize how samples will be handled, including treatment at Eniwetok, form in which the material will be shipped, and necessary initial treatment required before samples are ready for routine analysis. In Table III we summarize the kinds of analyses expected to be necessary, including a list of nuclides which have been detected in Eniwetok samples taken in earlier years. routine matter, Most of the samples will be GeLi gamma counted as a The question as to how many samples will require dissolution and wet chemical analyses can be answered accurétely only as the planning anda sample recovery progress. We need an assessment of the importance of 90g, analyses; we expect to infer Pu content from 2M da, measurements in some samples where more precise Pu analytical measurement by wet chemistry is not required, We anticipate that the more difficult oy Fe and 63 ~“Ni analyses will be performed only on selected samples, principally from the aquatic food chain.
