Abstract
A radiation dose detection device includes: a power supply circuit that outputs a power supply voltage; a temperature sensor unit that functions as a first current source that outputs a first current dependent on the ambient temperature, using the power supply voltage; a radiation sensor unit that functions as a second current source that outputs a second current dependent on the dose of radiation to the radiation dose detection device, using the power supply voltage; and a detection circuit that outputs a first signal indicating the temperature corresponding to the magnitude of the first current, and a second signal indicating the dose of radiation corresponding to the magnitude of the second current. The temperature sensor unit includes one or more resistance change elements each including a variable resistance layer containing a transition metal oxide. The second current source includes a transistor.
