About :
You use the Geiger-Müller counter to detect radiation such as alpha radiation, beta radiation or gamma radiation. We explain the structure and how it works in this video! You can find more videos on physics and chemistry at https://studyflix.de/. A Geiger-Müller counter consists of a metal tube, which is used to measure radiation, and the electronic measuring devices. The Geiger-Müller tube is filled with a noble gas under low pressure. This is subjected to a high voltage of around 400 to 900 volts. In order to stop the gas discharge, halogens or organic substances such as alcohol are also added to the noble gas. The Geiger counter counts either ionization events or radiation doses. Events are usually counted when you want to detect alpha radiation or beta radiation. This structure is the simplest. The output is either as a counting rate (events per second) or as a total measurement over a fixed period of time. Determining the radiation dose is more complex. The Geiger counter only detects the presence of radiation, but not its energy. However, the ionization of the radiation is significantly influenced by the energy. Therefore, you need a Geiger-Müller counter tube, which shows the dose in relation to the counting rate. The electronics use certain, predefined factors to establish this relationship. The choice here is tied to a device and depends on its structure and calibration. Click here to see the videos Alpha radiation https://studyflix.de/chemie/alpha-str...
