  • Page 11: Principle Of Operation

    1.4.2 Principle of operation The dosimeter uses an energy-compensated Geiger-Mueller counter as detector which converts photon radiation quanta to electric pulses to measure DER and DE of photon radiation. Processing of detector pulses, control over the LCD, control buttons, sound and vibration alarms is performed by the dosimeter’s built-in microcontroller.
