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 that is proportional to the radiation energy; hence the detector`s name. It is widely used where energy levels of incid....

A detection device for ionizing radiation. The proportional counter supplies proportional output pulses for primary ionization so that alpha and beta rays due to their different specific ionization can be traced separately. The proportional counter allows determination of the energy of radiation.
