  2. Geiger counter - Wikipedia

    en.wikipedia.org/wiki/Geiger_counter

    A Geiger counter consists of a Geiger–Müller tube (the sensing element which detects the radiation) and the processing electronics, which display the result. The Geiger–Müller tube is filled with an inert gas such as helium , neon , or argon at low pressure, to which a high voltage is applied.

  9. Counts per minute - Wikipedia

    en.wikipedia.org/wiki/Counts_per_minute

    Geiger-Müller counter with dual counts/dose rate display measuring a "point source". The dose per count is known for this specific instrument by calibration. The count rates of cps and cpm are generally accepted and convenient practical rate measurements. They are not SI units, but are de facto radiological units of measure in widespread use.
