Description/Abstract:
THE PLUTONIUM MASS ISOTOPIC ANALYSIS AND THE AMERICIUM-241 ANALYSES OF SOIL SAMPLES FROM ROCKY FLATS IDENTIFY THE CONTAMINATION AS PLUTONIUM WHICH WAS PROCESSED IN 1958. THE AMERICIUM-241 ACTIVITY IN THE SOIL WI LL REACH ITS MAXIMUM IN 2033 AND REPRESENT 18% OF THE PLUTONIUM -239-2 40 ACTIVITY. NUCLIDE RATIOS INDICATE THAT CURRENT OPERATIONS AT ROCKY FLATS CONTRIBUTE LITTLE TO THE AIRBORNE PLUTONIUM CONCENTRATIONS WHICH ARE DUE TO RESUSPENSION OF THE CONTAMINATED SOIL. ROOT UPTAKE OF PLUT ONIUM OR AMERICIUM BY VEGETATION IS SLIGHT OR SHOWS NO DISCRIMINATION AMONG THE ISOTOPES AND NUCLIDES STUDIED. THE RELATIONSHIP BETWEEN PLUT ONIUM DEPOSITION CONTOUR AND THE AREA ENCLOSED BY THAT CONTOUR HAS BEE N VERIFIED FOR CONTOUR VALUES EXTENDING OVER 7 ORDERS OF MAGNITUDE. TH IS GIVES CONFIDENCE TO OUR CALCULATIONS OF THE QUANTITIES OF PLUTONIUM RELEASED ON AND OFF THE ROCKY FLATS PLANT SITE.
