Although the Antarctic circulation cell is a statistical construct, its ability to transport trace gases and aerosols to the continent has been discerned experimentally by the use of deuterated methane atmospheric tracers. Atmospheric tracer experime

The deuterated methanes, 13CD4 and 12CD4, are useful as tracers for long-range (>500 km) atmospheric transport. They are easily synthesized and released. Sampling is accomplished by collecting about 330 l of air and chromatographically separating the

Technetium and plutonium in unprocessed nuclear reactor wastes are major concerns with regard to their containment in the geologic environment. Both nuclides have long half-lives; therefore, they will exist long after engineered barriers can be consi

Gadolinium isotopes were separated from a tantalum target which had been irradiated with 800-MeV protons. The concentrations of /sup 148/Gd in weighed aliquots of a solution of the isotopes were determined by isotope dilution mass spectrometry. Other

Measurements of the isotopic composition of methane in the Antarctic atmosphere have indicated the presence of either /sup 12/CD/sub 4/ or /sup 12/CHD/sub 3/. The concentration is about 1.3/times/10/sup /minus/16/(v/v). This concentration is at least
