Abstract:
1. A radiation detector comprising: a radiation sensitive semiconductor layer for generating carriers upon incidence of radiation; a high resistance film formed on an incidence surface of the semiconductor layer for selecting and transmitting the carriers; a common electrode formed on an incidence surface of the high resistance film applying a bias voltage to the high resistance film and the semiconductor layer; a matrix substrate formed on a surface opposite to the incidence surface of the semiconductor layer for reading, on a pixel-by-pixel basis, radiation detection signals from the carriers generated in the semiconductor layer; a curable synthetic resin film covering entire exposed surfaces of the semiconductor layer, the high resistance film and the common electrode; and an auxiliary plate fixed to an incidence surface of the curable synthetic resin film; wherein the auxiliary plate has a conductive and grounded surface opposite to a surface facing the curable synthetic resin film; and the curable synthetic resin film does not involve, as a raw material thereof, chlorine or a compound which includes chlorine.
