PURPOSE: A device and method for detecting radiation signals from radiation in different energy bands are provided to minimize misdiagnoses by outputting high quality radiation images. CONSTITUTION: A filter unit(21) arranges a plurality of unit filters(211). The unit filters selectively transmit components only in an energy band. A first unit sensor detects a radiation signal from the components in the energy band. A second unit sensor detects a radiation signal having different properties to the radiation signal from the first unit sensors.
