Abstract

A large area flat panel radiation detector for detecting neutrons and gamma rays includes at least two rigid components, a polymeric sealant providing a seal between the at least two rigid components, the at least two rigid components and polymeric sealant forming a radiation detection chamber, and a gas encapsulated by the chamber. A method of radiation detection in a radiation detector comprising a chamber, readout wires, readout electronics, and lithium foils, the method including collecting and amplifying the movement of charges in the radiation detector, measuring gamma-ray and neutron signals, providing a readout gas adjacent to the lithium foils, the readout gas causing the measured neutron signals to increase relative to the measured gamma-ray signals, and distinguishing between gamma-ray and neutron events based on the level of charge collected in the detector.
