Abstract

A radiation detection apparatus includes a first sensor panel that generates a signal in accordance with incident radiation, a second sensor panel that generates a signal in accordance with incident radiation, and an adhesive member that couples together the first sensor panel and the second sensor panel. When a stimulation is applied to the adhesive member, an adhesive force of the adhesive member is lowered to a strength at which the first sensor panel and the second sensor panel can be separated without causing damage.
