Last year, {sup 239}Pu was identified in 8 liter urine samples. This identification involved the establishment of an elution pattern characteristic of plutonium in which the track number decreased monotonically with volume of plutonium eluted from the column. This elution pattern was observed with urine obtained from middle aged adults born well before the 1960`s and in some younger adults, with less {sup 239}Pu being found in the latter. Both groups were from the general public and had no occupational exposure to plutonium. In addition, last year approximately 11 aCi/liter of {sup 239}Pu was found in synthetic urine. This was a surprising result, although this is a smaller amount than was found in normal human urine. Accordingly,the charges from the Advisory Committee included: (1) Identify the origin of the small amount of {sup 239}Pu found in synthetic urine and eliminate it, if possible; (2) Development of the automated track counting system; (3) Utilization of appropriate plutonium tracer to reduce the variation in the determinations of yield; (4) Collection of urine samples from various geographic locations of Utah and analysis of these samples; (5) Continue inter-laboratory comparison studies with Brookhaven National Laboratory, and other laboratories which possibly may have the capability of determining plutonium at similar levels.
