A Geiger counter provides a sensitive means of detecting radioactivity. A tube is filled with an inert gas, which will conduct electricity when radiation enters it. When a charged particle enters the tube, the electrical potential between the anode and cathode changes. 5 days ago Radiation detection is achieved through the use of a variety of instruments.
The most common type of radiation detector is a Geiger-Mueller (GM) tube, also called a Geiger counter. Many people, thinking about radiation detection, tend to group them all under the term “Geiger counters”, a misconception heartily encouraged by popular TV shows and movies. While one of the most common types of radiation detectors is called a “Geiger Mueller (G-M)” tube, the general phrase “Geiger counter” is not always the most appropriate. It applies to a very specific type of detector and, in general, to a specific application of that detector.
Radiation detection devices are typically classified by the type of detector element employed or by the application involved. People will refer to the instruments as an ion chamber, a probing meter, a contamination meter, or a Frisker probe. Popular culture has so profoundly subverted the proper use of “Geiger Counter” that the use of the phrase generally does not provide enough information about the device in question. There are several methods and equipment used to detect radiation.
These are film badges, gas ionization devices, Geiger-Muller counters, radon detectors, personal radiation detectors, fog chambers, and scintillation counters. If you've ever watched a movie or TV show where radiation detection was part of a scene, you probably used a Geiger-Müller counter to detect radiation. It is important to understand the different decay mechanisms of radiative sources to fully learn how to detect radiation, since different methods detect different forms of radiative decay. Some methods and machines detect radiation, each with its own unique way of detecting radiation.
Although they are intended to detect visible light, they can also detect the higher energies of ionizing radiation8.
