Until now gamma radiation detection has required large single crystals of sensitive materials that are difficult to produce consistently on an industrial scale. In collaboration with a research group at the University of Texas at Arlington, Agiltron proposes to develop a new class of nanocomposite scintillator materials. The radiation detection characteristics of the synthetic nanoparticles in the ...

High-resolution scintillation crystals and crystal arrays are important components of current and future handheld and arrayed detectors (used for DOD/DTRA applications), and scintillation spectrometers (routinely used in high energy physics research, medical imaging, diffraction, homeland security, nuclear waste clean-up, nuclear treaty verification and safeguards, and geological exploration). Un ...

Physical Sciences Inc. proposes to continue development of a software tool that is capable of defining the selection and placement of a constellation of standoff and point sensors for the protection of base facilities and forces deployed in the field. The network will be defined using an algorithm that optimizes the collective performance of the sensors as a function of deployment need, geography, ...

Doctrine for employment of canines in a CBRN environment has evolved into a Collective Protection approach. Providing COLPRO has several very significant implications for Canine kennels and shelters: „X The outer surface of the structure must be CB agent impervious „X The outer surface of the structure must resist effects of the decontamination process „X The system must provide the animal ...

Airborne chemical and biological (CB) agents released in one section of a building travel via the building’s heating, ventilating, and air conditioning (HVAC) systems and disperse throughout the building, while undergoing deposition and resuspension recurrently. Computational fluid dynamics (CFD) has been employed to simulate dispersion of CB agents in a building through HVAC systems. How well t ...

Spectral Sciences Inc. proposes to develop a prototype sensor for real-time trace-level analysis of complex multicomponent gas mixtures, specifically those containing Chemical Weapon (CW) agents and interferents. The instrument is based on high power quantum cascade lasers and photocoustic spectroscopy detection. Advanced detection algorithms take advantage of wide spectral coverage to provide hi ...

The complexity of Atmospheric Transport and Dispersion (ATD) modeling requires physically consistent weather data evolving in both space and time. Spatially and/or temporally averaged data found in climatological products is not suitable for ATD modeling. The proposed solution for providing “typical day” meteorological data couples innovative search techniques applied to long-range historical ...

Atmospheric and Environmental Research, Inc. proposes to develop a prototype threat-reduction system for the dispersion of a weapons-of-mass destruction warhead in the upper atmosphere. Our system will extend current DTRA atmospheric transport and dispersion capabilities into the 20-120 km altitude region. This will be accomplished using a combination of a zonally-averaged transport model of the s ...

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 ...

U.S. forces working in low-level radiation environments have unsatisfactory choices for monitoring radiation exposure. A solid-state photomultiplier (SSPM) uses an array of silicon based avalanche photodiodes (APD) to collect light and produce a signal proportional to the amount of light collected. The ability to produce arrays of APD’s in a CMOS (Complimentary Metal Oxide Semiconductor) envir ...
