The isotopic ratios of fission gas would provide important source information a nuclear fuel sample found in the environment. However, it is believed that during reactor accident like Chornobyl all lost and radioactive particles Exclusion Zone today are depleted gases by initial explosion subsequent fire. We disprove this hypothesis detection analysis trapped krypton xenon these particles. Our isotopes noble mass spectroscopy combination with resonance ionization spectrometry establishes...

Microscopic fuel fragments, so-called "hot particles", were released during the 1986 accident at Chornobyl nuclear powerplant and continue to contaminate exclusion zone in northern Ukraine. Isotopic analysis can provide vital information about sample origin, history contamination of environment, though it has been underutilized due destructive nature most mass spectrometric techniques, inability remove isobaric interference. Recent developments have diversified range elements that be...
Abstract The Chemical Weapons Convention is a science-based international treaty for the disarmament and non-proliferation of chemical weapons. Organisation Prohibition (OPCW) serves as its implementing body. bans chemicals weapons, includes verification mechanism to monitor compliance, requires scientific technical expertise effective implementation. This necessitates continuous engagement with communities, whether informal or institutionalized (as demonstrated by Designated Laboratories,...
Abstract Advances across the chemical and biological (life) sciences are increasingly enabled by ideas tools from sectors outside these disciplines, with information communication technologies playing a key role 21 st century scientific development. In face of rapid technological change, Organisation for Prohibition Chemical Weapons (OPCW), implementing body Convention (“the Convention”), seeks opportunities to strengthen capabilities in field disarmament. The OPCW Scientific Advisory Board...
Microscopic fuel fragments, so-called ``hot particles'', were released during the 1986 accident at Chornobyl nuclear powerplant and continue to contaminate exclusion zone in northern Ukraine. Origin, age, environmental weathering of material can be determined via isotopic analysis, providing vital information about sample history contamination environment. A comprehensive study structure composition single hot particles from Exclusion Zone (CEZ) was made using isotope ratios actinides...
Abstract In this work, uranium-and plutonium-baring particles were produced by fast iron co-precipitation for the purpose of creating homogeneous multi-element standards. A set single isolated showing no inhomogeneities in element distribution selected. These used to determine maximal achievable suppression ratios uranium Resonant Laser Secondary Neutral Mass Spectrometry (rL-SNMS) measurements plutonium. It was shown first time directly that suppression-ratios order three magnitudes are...
