Abstract
An X-ray detector includes a first circuit with an NPN-type bipolar transistor and a second circuit configured to compare a voltage at a terminal of the NPN-type bipolar transistor with a reference value substantially equal to a value of the terminal voltage which would occur when the first circuit has been exposed to a threshold quantity of X-rays.
