As part of the technical support CST-12 provides for a wide variety of defense and nondefense programs within Los Alamos National
Laboratory (LANL) and the Department of Energy (DOE) complex, new waste minimization technique is under development for radiological
volatile organic analysis (Hot VOA). Currently all Hot VOA must be run in a glovebox. Several types of samples contain TRU
radiological waste in the form of particulates. By prefiltering the samples, through a 1.2 micron syringe and counting the
radioactivity, it has been found that many of the samples can be analyzed outside of a glovebox. In the present investigation,
the types of Hot VOA samples that can take advantage of this new technique, the volume and types of waste reduced, and the
experimental parameters will be discussed. Overall, the radioactive waste generated is minimized.

Marked increases in the concentrations of thorium and uranium isotopes observed in rain samples collected at Fayetteville (36° N, 94° W), Arkansas, during 1983 are attributed to the fallout from the 1982 eruption of El chichón volcano in Mexico.
