    Analysis of IAEA environmental samples for plutonium and uranium by ICP/MS in support of international safeguards

    A method for the separation and determination of total and isotopic uranium and plutonium by ICP/MS was developed for IAEA samples on cellulose-based media. Preparation of the IAEA samples involved a series of...

    Environmental applications of stable xenon and radioxenon monitoring

    Characterization of transuranic waste is needed for decisions about waste site remediation. Soil-gas sampling for xenon isotopes can be used to define the locations of spent fuel and transuranic waste. Radioxe...

    Determination of plutonium isotope ratios at very low levels by ICP-MS using on-line electrochemically modulated separations

    Electrochemically modulated separations (EMS) are shown to be a rapid and selective means of extracting and concentrating Pu from complex solutions prior to isotopic analysis by inductively coupled plasma mass...

    Underground sources of radioactive noble gas

    It is well known that radon is present in relatively high concentrations below the surface of the Earth due to natural decay of uranium and thorium. However, less information is available on the background lev...

    Noble gas migration experiment to support the detection of underground nuclear explosions

    A Noble Gas Migration Experiment injected 127Xe, 37Ar, and sulfur hexafluoride into a former underground nuclear explosion shot cavity. These tracer gases were allowed to migrate from the cavity to near-surface a...
