A CURRENT REVIEW OF BODY FLUID ANALYSIS, PROCEDURES, AND METHOD OF REPORTING--JANUARY 1957

Description: Direct alpha counting to determine fissile material in dilnte solutions of high total solids content is likely to be inaccurate due to the difficulty of preparing thin sources. This report describes a neutron-activation analysis method which eliminates this risk. Results obtained by the neutronactivation analysis for U/sup 238/ in solution are compared with results obtained from other methods. The standard deviation and sensitivity are shown. (auth)

TECHNIQUES USED FOR THE PRODUCTION AND IDENTIFICATION OF THE TRANSPLUTONIUM ELEMENTS

Description: Presented at Mendeleev Chemistry Conference, Moscow, March 1953. A study was made of the production and identification of the transplutonium elements with atomic number greater than 94. A detailed discussion is presented of the identification of elements 101 and 102 and the possible applications of these methods to elements beyond. A brief review of the discovery of all of the transplutonium elements is given to show the gradual change in experimental techniques. (J. E. D.)
