Scintillator Based Radiation Detectors for Emergency Response

Description:

We would like to support research on materials that will lead to practical high-brightness scintillators with energy resolution significantly better than the currently available sodium iodide-based gamma spectrometers. Several new and promising formulations have been discovered and synthesized in small quantities, but have not reached the level of commercial availability necessary to make an operational impact. The ideal scintillator for an emergency response handheld and-or backpack would have at least 50% higher resolution and would be sensitivity to thermal neutrons using pulse-height discrimination. A crystal larger than 50 mm by 50 mm would also be desired. Phase I: Identification of a suitable detector material and demonstration of a lab prototype. Phase II: The development of a commercial process for the growth and packaging of the material to make a portable radiation detector.
