Method for the detection of ionizing radiation

摘要

The method involves measuring photons emitted by a scintillator (10) using a single photon counter (40), where the scintillator has a component having a decay time of over 100 nanoseconds. The counter has a photomultiplier, a stabilized high voltage supply and an amplifier providing a standard pulse output. The rate of an output signal of the counter is processed directly for measuring intensity of ionizing radiation. An independent claim is also included for an arrangement for executing a method for detecting ionizing radiation.
