Description/Abstract:
FROM PROCEEDINGS OF ENVIRONMENTAL PLUTONIUM SYMPOSIUM HELD AT LASL, AU GUST 4-5, 1971. PLUTONIUM ANALYSES HAVE BEEN PERFORMED AT TRAPELO/WEST FOR OVER TWENTY YEARS. IN RECENT TIMES, PROCEDURAL CHANGES HAVE BEEN MADE TO OBTAIN COMMONALITY IN METHODS FOR ANALYZING PU IN DIFFERENT M ATRICES. PROCEDURES USED FOR PU ENVIRONMENTAL SAMPLES SUCH AS WATER, S OIL, AIR, VEGETATION, AND BIOLOGICAL AND MARINE SAMPLES ARE DISCUSSED. INITIAL STEPS INVOLVE TOTAL DISSOLUTION, LEACHING OR ASHING, AND EQUI LIBRATION WITH TRACER PU-236 TRACER IS USED IN ALL CASES SINCE IT RESU LTS IN THE MOST RELIABLE DATA. AN ANION EXCHANGE PROCEDURE IS THE BASI C PART OF THE PURIFICATION. AN EFFICIENT ELECTRODEPOSITION STEP PERMIT S PLATING IN TEN MINUTES. RADIOACTIVITY MEASUREMENTS ARE MADE USING EI THER FRISCH GRID IONIZATION CHAMBERS OR SURFACE-BARRIER DETECTORS. SPECIFIC PROBLEMS LIKELY TO BE ENCOUNTERED IN PLUTONIUM ANALYSIS ARE D ISCUSSED. PROBLEMS ENCOUNTERED IN MEASURING AND STATING ERROR LIMITS A T VERY LOW LEVELS SO THAT THEY MAY BE USED PRACTICALLY ARE DISCUSSED.
