ABSTRACT:
An improved system of circuitry for operating an electronic counter connected to a Geiger-Mueller (GM) tube or to a similar source of random pulses with an associated dead time making the system response linear at increased counting rates, includes an electronic one-shot device, an and-gate connected to a pulse counter, a second and-gate connected to an interval counter, and a frequency source for producing periodic clock pulses. When a GM tube is operated as a part of this system, it detects ionizing radiation by producing pulses at a rate proportional to the amount of radiation present. The one-shot inhibits further GM-tube pulses from entering the pulse counter for a fixed time selected to be somewhat longer than the maximum GM-tube dead time, and at the same time it inhibits further periodic clock pulses from entering the interval counter, automatically correcting the measured and displayed pulse count for dead time without regard to the precise value of the dead time of the GM tube or other pulse source.
