“…By this time, the ionization efficiency of solid-source mass spectrometers had been improved by the use of activators ( (1981) have also been able to enhance ion yields from plutonium and uranium by loading a slurry of rhenium powder with a solution of sucrose in water onto the filament, whereas Perrin et al (1985) used a rhenium filament overplated with platinum to optimize the analysis of plutonium in nanogram-sized samples. These techniques enabled sample sizes to be reduced without sacrificing accuracy and precision, and enabled Rosman et al (1983) to analyze subnanogram samples of fission-product tin by conventional solid-source mass spectrometry.…”

EXECUTIVE SUMMARYUse of a uranium double spike in analysis of environmental samples showed that a 235U enrichment of 1% (235U/L38U = 0.00732) can be distinguished from natural (235U/238U = 0.00725). Experiments performed jointly at Los Alamos National Laboratory (LANL) and Oak Ridge National Laboratory (ORNL) used a carefully calibrated double spike of 233U and 236U to obtain much better precision than is possible using conventional analytical techniques.A variety of different sampling media (vegetation and swipes) showed that, provided sufficient care is exercised in choice of sample type, relative standard deviations of less than f 0.5% can be routinely obtained. This ability, unavailable without use of the double spike, has enormous potential significance in the detection of undeclared nuclear facilities.

“…Lichen samples also were collected from Amchitka and Adak Islands to provide radionuclide concentration data that can be compared to data from other North American locations, particularly with respect to inputs from Chernobyl Perrin et al (1985). Together this information will allow a first approximation of the radionuclide inventory, if present, in the media sampled and should also provide information concerning the most likely source of the radionuclides.…”
