Nuclear Explosion Monitoring Research and Development Roadmaps
In the past ten years, significant progress has been made in nuclear explosion monitoring (NEM) through research and development (R&D) with regard to detection, location and identification, however substantial improvements are yet possible. Today, there is increasing interest in both current and planned NEM R&D technology particularly in light of its relevance to the Comprehensive Nuclear-Test-...
متن کاملCHARACTERIZATION AND PERFORMANCE EVALUATION OF AN HPXe DETECTOR FOR NUCLEAR EXPLOSION MONITORING APPLICATIONS
Expanding missions in nuclear explosion monitoring (NEM) and nuclear security have highlighted the need for high-resolution ambient-temperature gamma detectors that can provide radionuclide-specific monitoring under demanding field conditions. Recent improvements in high-pressure xenon (HPXe) detectors indicate that this technology has potential to provide rugged, large volume ambient temperatu...
متن کاملIsotopic noble gas signatures released from medical isotope production facilities--simulations and measurements.
Radioxenon isotopes play a major role in confirming whether or not an underground explosion was nuclear in nature. It is then of key importance to understand the sources of environmental radioxenon to be able to distinguish civil sources from those of a nuclear explosion. Based on several years of measurements, combined with advanced atmospheric transport model results, it was recently shown th...
متن کاملProgress on Component Evaluation for Nuclear Explosion Monitoring
The Ground-Based Nuclear Explosion Monitoring Research and Development (GNEM R&D) program at Sandia National Laboratories (SNL) is regarded as the primary center for unbiased expertise in testing and evaluation of geophysical sensors and instrumentation for nuclear explosion monitoring. We had four main areas of interest to make progress on this year; this report will cover the advances made in...
متن کاملEvaluation of radioxenon releases in Australia using atmospheric dispersion modelling tools.
The origin of a series of atmospheric radioxenon events detected at the Comprehensive Test Ban Treaty Organisation (CTBTO) International Monitoring System site in Melbourne, Australia, between November 2008 and February 2009 was investigated. Backward tracking analyses indicated that the events were consistent with releases associated with hot commission testing of the Australian Nuclear Scienc...
