Ionization chamber and proportional counter
The proportional counter is a type of gaseous ionization detector device used to measure particles of ionizing radiation. The key feature is its ability to measure the energy of incident radiation, by producing a detector output pulse that is proportional to the radiation energy absorbed by the detector due to an ionizing event; hence the detector's name. It is widely used where energy levels of incident radiation must be known, such as in the discrimination between alpha and beta … WebIonization Chamber vs Proportional Counter In general, the ionization chamber and also the proportional counter are types of gaseous ionization detectors. These can be categorized according to the voltage applied to the detector: ionization chambers, …
