We propose schemes of using graphene field effect transistors (GFET) to detect ionizing radiation. The detection is based on the high sensitivity of graphene to local change of electrical field that can result from the interaction of radiation with a semiconductor substrate in a GFET. We present preliminary modeling and experimental work to develop a prototype sensor, and discuss potential advantages compared to conventional detectors.
