Abstract This high performance, micro-electronic, radiation-monitoring device, utilizes chalcogenide glass (ChG) characteristics to quantify radiation exposure. The device consists of a two-terminal design with a mobile active phase incorporated onto a ChG film. Radiation exposure causes diffusion of the mobile phase into the ChG film reducing resistance between the two terminals in a linear fashion. The various properties of the chalcogenide glass family allow this device to be tailored for a variety of sensitivities including doses over 1 Mrad. The unique design allows this device to be integrated into circuits for real time measurements. It can also act as a standalone device to measure cumulative radiation doses with no power consumption. In both functions the detection is reversible allowing for calibration and reuse. This device can be utilized in a range of environments ranging from monitoring individuals in a lab setting to monitoring nuclear power sources or nuclear waste storage.
