Abstract
According to an embodiment, a radiation detector includes: a substrate; multiple control lines; multiple data lines; multiple detecting parts detecting radiation including thin film transistors; a control circuit switching between ON and OFF-states of the transistor; a signal detection circuit reading image data when the transistor is in the ON-state; and an incident radiation detecting part determining an incidence start time of the radiation based on a value of the image data read when the transistor is in the ON-state. When the incident radiation detecting part determines that radiation incidence has started, the signal detection circuit performs a first reading process of further reading image data when the transistor is in the ON-state. The control circuit performs an image storage process of setting all of the transistors to the OFF-state after the first reading process.
