20 DSGH Installation and Operation Guide
Introduction
• Inside the detector is a scintillator material, which produces light in
proportion to the intensity of its exposure to radiation.
• A photomultiplier tube detects the scintillator's light and converts it into
voltage pulses.
• The microprocessor receives these voltage pulses after amplification and
conditioning by the photomultiplier tube.
• The microprocessor and associated electronics convert the pulses into an
output that can be calibrated.
