Physical Sciences Inc. (PSI) proposes to develop a PCS-Enabled Unattended Radiation Detection and Attribution System (PURDAS) that will be able to detect, identify, and attribute radiological sources to specific source carriers or conveyances. The PURDAS will include a COTS gamma and neutron detection capability as well as a visible camera, onboard processing, and wireless radios. PURDAS units wil ...

Traditionally, implementation of dedicated, continuous nuclear and radiological monitoring systems for identifying and tracking nuclear materials out of regulatory control is associated with high operational burdens. Although video and images from cameras are helpful in assessing threats, the raw, unstructured data require time-intensive human interaction to extract the relevant actionable informa ...

The implementation of continuous nuclear and radiological monitoring systems enabling the automatic detection and tracking of potential nuclear threats is traditionally associated with a high operational burden. Sensors typically have to be monitored by dedicated personnel, who must investigate detection events in a timely manner; however, high nuisance alarm rates can rapidly overwhelm already-ta ...

A Phase I SBIR is proposed for the development of a wearable sensor to protect law enforcement and first responders from inadvertent exposure to potentially toxic levels of fentanyl and/or fentanyl analogs.The Phase I project will demonstrate the ability of the new sensor to selectively detect the presence of fentanyl analog vapors from solid samples or air-borne particulates in concentrations bel ...

Nano Terra proposes to develop a low-cost and wearable detector badge that quickly and selec-tively alerts the user to the presence of solid fentanyl aerosols with an audible and visual alert. Current commercial fentanyl and opioid detectors are bulky and costly and have unsuitably-high limits of detection. Nano Terra will leverage their expertise in ultra-sensitive dosimetric detection of threat ...

Electron accelerators that produce high duty cycle electron beams with beam energies up to 9 MeV are essential for use in practical Nuclear Resonance Fluorescence and EZ-3DTM imaging technologies. While isotopic identification of shielded materials is now possible via these technologies, it is still necessary to achieve accelerator portability, compactness and reasonable cost of ownership to make ...

In Phase I, the Peerless team developed an approach for an innovative wizard driven, turn-key, system that can be used by inexperienced operators to quickly design new sensor networks and evaluate existing sensor networks for the protection against and detection of CB agents within public structures. For Phase II, Peerless will conduct three development spirals to build the prototype system, valid ...

Non contact trace explosives detection has not been comparable to results obtained from wipe sampling. Many issues, including finding a method to release particles from a surface, efficient particle and vapor transport, and limited particle and vapor trap collection efficiency have all limited the process. Other related issues have included cost of ownership, ease of contamination removal, and com ...

Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Preventing 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. One way to passively determine the presence of nuclear weapons is to detect and identify characteristic signatures of ...

Gamma-ray spectrometers consisting of inorganic scintillators coupled to optical detectors such as photomultiplier tubes (PMTs) are an important element of the systems that are used to monitor and prevent the spread of special nuclear materials. Two very important requirements for the scintillation detectors used as gamma-ray spectrometers in homeland security monitoring include high sensitivity a ...
