Wearable Radiation Sensors
Abstract
The Nu-Trek team is proposing to develop the micro GmRH, a low Size, Weight, Power, and Cost (SWaP/C) radiation-hardened gamma dosimetry module which will replace dosimeters based on Geiger-Muller (G-M) tubes in radiation detectors (RADIACs). A RADIAC using the micro GmRH solution will be smaller, lighter, and have longer battery life than one using G-M tubes. The micro GmRH has two key components: A cadmium zinc telluride (CZT) detector and a custom readout integrated circuit (IC), the micro DetRH IC. The micro DetRH IC replaces a number of discrete component with a single IC resulting in the large SWaP/C savings. In Phase I the Nu-Trek Team developed a baseline design for the micro DetRH, with particular attention paid to radiation hardness and meeting SWaP/C requirements. In Phase II the design of the micro DetRH will be completed and fabricated. Phase II will culminate with the integration and testing of the micro GmRH, delivering modules that will be available for evaluation by potential end users. To meet the Army's productization requirements, Nu-Trek has teamed with a major supplier of CZT. The micro GmRH is expected to meet topic requirements.
