NDT Corp. will take the currently developed ACTT system, which can accurately assess the internal condition of concrete crossties and increase its speed.FRA 23-FR1 requests a system that at high speeds can assess both the internal and external condition of concrete crossties.Currently there are systems that can perform the external assessment at the required speeds.However, there is no system that ...

Physical Sciences Inc. proposes to develop and mature the Network Fusion Radiation Analysis Tool (NFRAT) to address the need for an enhanced radiation hazard mapping, localization and identification capability in support of contamination avoidance operations and sensitive site exploitation. The NFRAT software will utilize dynamic representations of the radiological environment and statistical mode ...

This work is focused on the development of fabrication technology for large form-factor scintillation crystals for multi-modal detection of radioactive sources, and development of mobile imaging and mapping instruments based on these large format scintillators.

Gamma dosimetry is an integral part of radiation safety and protection for a wide range of military operations. For these applications, Geiger Müller (GM) tube is used as the standard gamma dose rate sensor. The cost-to-performance metric for this sensor type has reached a plateau and new sensor materials are needed for the next generation of dosimeters. Recently there has been a vast development ...

Atom Trap Trace Analysis (ATTA) has proven to be a valuable technique for detecting rare gas radioisotopes. By tuning the frequency of a laser to the resonance of a desired isotope, only atoms of that isotope are captured by a magneto-optical trap (MOT) and detected by observing its fluorescence with a CCD camera. Existing approaches rely on manually selecting a region-of-interest (ROI) of image p ...

The event of nuclear explosion generates harsh radiation conditions, evaluation of which is critical in protecting the military and civilian personnel from serious harm.  Due to these harsh conditions only very simple methods of radiation assessment are employed, such as measurement of equivalent dose.  Improvements to current instrumentation are sought that would provide energy resolved dose in ...

In the condition of a nuclear event, it is critical that warfighters and first responders are equipped with active dosimeters and dose rate meters.  These tools can be made from scintillation-based detector systems that require a high performance photodetector.  The silicon photomultiplier is a compact photodetector that would be ideal for such a detector system, yet their performance suffers fr ...

First responders to hazardous material (HAZMAT) incidents face many safety risks daily, such as exposure to hazardous chemicals and toxic gases, which can be difficult to detect. Although there have been advancements in wearable sensors for hazardous gases, sensor technology for HAZMAT incident response lags behind sensor technology advancement in biomedical fields. There is a need to integrate se ...

This research proposes a data-driven and multi-perspective solution to reduce injuries and fatalities due to bus collisions with other vehicles. It goes beyond reviewing historical bus crash reports by collecting field LiDAR data for better understanding a variety of factors that may contribute to bus collisions and injuries/fatalities. It also recognizes that collision avoidance technologies (whi ...

Pipeline and Hazardous Materials Safety Administration (PHMSA) is actively involved in the safe transportation of energy and hazardous material that are vital to daily lives. This also includes underground natural gas storage (UNGS) maintenance and safe operation which are critical to nation's energy infrastructure. Enhancing leak detection and identifying smart ways to prevent potential well blow ...
