Solid state radiation detector and method for testing the same

A solid state radiation detector, comprising:

• a solid state detecting section constituted by a set of layers layered in the order of:
• a first conductive layer having transparency to recording light,
• a recording photoconductive layer that shows conductivity when exposed to the recording light;
• a charge storage section for storing an amount of electric charges corresponding to the amount of the recording light;
• a readout photoconductive layer that shows conductivity when exposed to readout light;
• and
• a second conductive layer having multitudes of charge detecting linear electrodes and multitudes of auxiliary linear electrodes, the charge detecting linear electrodes and auxiliary linear electrodes being arranged alternately;
• a test signal generating means for generating a test signal;
• and
• a connection switching means for connecting at least one end of the auxiliary linear electrodes to either the test signal generating means or ground.
