ABSTRACT:
A method and apparatus for detecting and measuring radiation is disclosed. The apparatus includes a scintillator crystal and a photodetector optically coupled to the scintillator crystal as well as first and second analyzing means. The first analyzing means is coupled to an output of the photodetector for counting discrete electronic pulses generated by the photodetector. The second analyzing means operates simultaneous with the first analyzing means and is coupled to another output of the photodetector for integrating current generated by the photodetector. The method includes the steps of irradiating a scintillator with x-ray energy, detecting light emitted from the scintillator and converting the light into a flow of electrons, detecting and counting discrete pulses of the flow of electronics and simultaneously integrating electronic current corresponding to the flow of electrons.
