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 … WebA Proportionate counter is an instrument for detecting and measuring the intensity of ionizing radiation. It is similar to a Greiger Mueller counter but operates at a lower …
