Description

A portable device for measuring of radiation having at least two Geiger-Muller counter tubes and of different sensitivity. A high-voltage supply is in connection with each Geiger-Muller tube and pulse shaping devices are connected to the Geiger-Muller tubes to generate ouput signals based on the intensity of radiation. A high-speed counter is coupled to the pulse shaping devices. A microprocessor includes program storage and random access memory and is capable of switching between the Geiger-Muller tubes based on the radiation intensity. Information generated by the high-speed counter and the microprocessor is visually displayed. Stable and accurate readings are made at low radiation intensity while providing quick response to significant changes in radiation intensity. (author)
