    Low level detection of 135Cs and 137Cs in environmental samples by ICP-MS

    The measurement of fission product cesium isotopes 135Cs and 137Cs at low femtogram (fg) 10−15 levels in ground water by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) is reported. To eliminate the natural...

    Microscopic evaluation of contaminants in ultra-high purity copper

    Copper is one of few elements that have no long-lived radioisotopes and which can be electrodeposited to ultra-high levels of purity. Experiments probing neutrino properties and searching for direct evidence o...

    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...

    Remote sensing volatile elements for new signatures from underground nuclear explosions

    The detection of radioactive noble gas isotopes is one of the key tools in detecting underground nuclear explosions, but other volatile elemental species, that have historically been overlooked, may also migra...

    Generating aerodynamic surrogate nuclear explosion debris (SNED)

    “Aerodynamic debris” has often been observed from explosion debris collected on the fringe of surface nuclear tests. The material forms small glassy particulates, ranging in shape from near perfectly spherical...
