DTRA uses high-resolution mesoscale forecasts to drive HPAC, the DTRA dispersion modeling tool that generates critical forecasts of dosage resulting from releases of chemical, biological, or radiological agents. HPAC is designed to provide probablistic information based on estimates of the uncertainty of the input forecast fields of the meteorological variables (wind, temperature, etc.). ...

U.S. forces working in low-level radiation environments have unsatisfactory choices for monitoring radiation exposure. The currently available A/UDR-13 pocket dosimeter is able to meet sensitivity requirements, but is cost prohibitive at ~$400 per unit, and it fails in the high temperature environments faced our military. Careful monitoring and accurate reporting of the exposed dose will reduce t ...

Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Prevention of the spread of nuclear weapons has reached a state of heightened urgency in recent years, especially since the events on September 11, 2001 and its aftermath. Gamma ray spectrometers are an important tool in checking the proliferation of the nuclear weapons. Important re ...

Conventional weapons rely on blast and fragmentation as the primary defeat mechanism, whereas non-energetic payloads rely on other means to defeat the target. Non-energetic weapons may defeat targets by the dispersion of aerosols (solid or liquid) or gases to interact with critical target elements. The objective is to cause some combination of denial, disruption, degradation, or destruction witho ...

A visualization package is proposed for the real time visualization of three-dimensional, time-varying hazards data generated by existing and next generation hazard and consequence assessment software. The Hazard Prediction Assessment Capability (HPAC) software will be used as a representative consequence assessment toolset, and the new visualization capability will be integrated in a manner appli ...

Strategic DoD satellite and missile systems (Space Based Radar, Space Tracking Surveillance Systems) operate in harsh radiation environments, and will be increasingly based on novel sub-100-nm semiconductor technologies and highly complex circuits. In order to ensure interruption-free operation, accurate prediction of the radiation response of these technologies and circuits is critical. To addres ...

We propose to evaluate the improvement of atmospheric transport and dispersion model accuracy by synergistically combining mesoscale (NWP) and microscale (CFD) models in a manner suitable for an operational environment. The feasibility of a fully-coupled, combined, operational model will be addressed in the Phase I study by evaluating improved urban area transport behavior using OMEGA generated wi ...

Discontinuous graphite fiber reinforced aluminum magnesium matrix composite with microscopically dispersed add-on oxidizer coating is proposed for the application of enhanced lethality munitions. The composite with the coating is light-weight and reactive, which will generate high reaction temperature and a large amount of reaction heat. The composite also has sufficient mechanical strength for ...

NOVA Scientific will demonstrate a large-area/low-cost neutron detection system having high neutron sensitivity with very high signal-to noise ratio. The approach utilizes an embedded neutron absorber in a solid state detector based upon known Microchannel Plate (MCP) processing technology. The system detects concealed fissionable materials located several meters away, by converting the neutron si ...

Physitron proposes the development of a Thermal Neutron Beam Concentrator for use in detecting strategic nuclear material (SNM) such as U, Pu, Th, etc. A compact neutron generator developed by Lawrence Berkeley National Lab will provide 2.4 MeV neutrons that will be moderated, concentrated into a high flux beam, and propagated in air across distances up to three meters. Any SNM in the beam's path ...
