Fission track analysis of plutonium in small specimens of biological material: Ultrasensitive analysis for (239)Pu in 50 urine samples from the Marshall Islands furnished by Brookhaven National Laboratory. Final technical report, October 1, 1986-September 30, 1989

摘要

A neutron induced fission track method was successfully developed for assaying (sup 239)Pu in human urine. The technique involves means to remove potentially interfering natural uranium from the sample and reagents. The method was applied to 50 urine samples including an unknown number of spikes and controls from the Marshall Islands. 49 samples were successfully analyzed. The mean activity for the 47 samples which were not positive for (sup 239)Pu did not differ significantly from the mean for our control samples, which consisted of urines collected from six young adult Utah residents. 2 figs., 12 tabs.
