A Geiger counter (/ ˈ ɡ aɪ ɡ ər /, GY-gər; [1] also known as a Geiger–Müller counter or G-M counter) is an electronic instrument used for detecting and measuring ionizing radiation. It is widely used in applications such as radiation dosimetry , radiological protection , experimental physics and the nuclear industry .
The CD V-700 is a Geiger counter employing a probe equipped with a Geiger–Müller tube manufactured by several companies under contract to US federal civil defense agencies in the 1950s and 1960s. This unit is quite sensitive and can be used to measure low levels of gamma radiation and detect beta radiation. In cases of high-radiation fields ...
The RBGT-62a was a Geiger counter manufactured in the early 1960s for the Czechoslovak People's Army.It read beta and gamma and had a transistorised circuit. The dial, controls, headphone jack, and probe connector are on the front of the meter, and the battery compartment on the back.
Scientists invented the Geiger counter, which measures radioactivity, while working on experiments to prove that the center of an atom contains a nucleus.
Geiger–Müller tubes are the primary components of Geiger counters. They operate at an even higher voltage, selected such that each ion pair creates an avalanche, but by the emission of UV photons, multiple avalanches are created which spread along the anode wire, and the adjacent gas volume ionizes from as little as a single ion pair event.

The Geiger–Müller tube or G–M tube is the sensing element of the Geiger counter instrument used for the detection of ionizing radiation. It is named after Hans Geiger , who invented the principle in 1908, [ 1 ] and Walther Müller , who collaborated with Geiger in developing the technique further in 1928 to produce a practical tube that ...
The CD V-700 (often written as "CDV-700") is a Geiger counter employing a probe equipped with a Geiger–Müller tube, manufactured by several companies under contract to United States federal civil defense agencies in the 1950s and 1960s. While all models adhere to a similar size, shape, coloring and form-factor, there were substantial ...
