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 for detecting and measuring ionizing radiation with the use of a Geiger–Müller tube.

Feb 13, 2019 · This instrument is actually used for detecting and measuring ionizing radiation like alpha particles, beta particles, and gamma rays. A Geiger-Müller counter can count individual particles at rates up to about 10,000 per second and is used widely in medicine and in prospecting for radioactive ores. Construction of Geiger-Muller counter

Apr 19, 2022 · A Geiger counter, also known as the Geiger-Muller tube, is an inexpensive and useful instrument used to quickly detect and measure radiation.

Mar 19, 2020 · A Geiger counter has two main parts—a sealed tube, or chamber, filled with gas, and an information display. Radiation enters the tube and when it collides with the gas, it pushes an electron away from the gas atom and creates an ion pair.

Geiger Counter or the GM counter is a device that is used to detect and measure particles in the ionized gases. Invented by Geiger and Muller, it is a revered radiation detection instrument.

Mar 9, 2021 · Geiger-Mueller counter. A radiation detection and measuring instrument. It consists of a gas-filled tube containing electrodes, between which there is an electrical voltage, but no current, flowing.

Jun 9, 2023 · In reality, though, the Geiger counter — which in the scientific and engineering world is known as the Geiger-Muller counter — is an actual device that's still frequently used to detect radiation in various settings.

Jan 22, 2025 · Geiger and Muller invented a particle detector to monitor ionizing radiation in 1928, naming it the ‘Geiger Muller Counter’. It is composed of a metallic tube filled with gas and subjected to a high voltage range of multiples of 100V. It is capable of detecting alpha, beta, and gamma particles.

The Geiger-Müller tube stands out for its simplicity, efficiency, and effectiveness in detecting ionizing radiation. By leveraging the ionizing properties of radiation and the gas amplification process, it provides a direct and quantifiable means of radiation measurement.

A Geiger counter, also known as a Geiger-Muller counter, is used to detect and measure ionizing radiation. It operates based on the ionization effect produced by radiation when it interacts with matter.
