A reusable solid state device is disclosed which monitors ionizing radiation. The device is a silicon-on-sapphire n-channel MOS transistor having a back-channel leakage current which is proportional to total radiation dose. To return the monitor to its original reusable state, the drain-to-source transistor bias is reduced to zero while irradiating the device to an appropriate dose level. Author
