Patented Electronically Collimated Gamma Radiation Detector aids Warfighters
A tube operated in gas proportional mode produces waveforms displayed on an oscilloscope. Subsequently these waveforms were captured with high-speed, analog-to-digital electronics. The instrumentation was used by U.S. Army Engineer Research and Development Center Environmental Laboratory researchers in Vicksburg, Mississippi, to develop an electronic collimator invention for detecting gamma radiation, a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. The invention enables the warfighter with a detector capable of directional detection without the use of shielding. (U.S. Army Corps of Engineers photo)
