An ionization chamber is a type of radiation detector that measures ionizing radiation by collecting and measuring the charge created when radiation interacts with a gas within the chamber. It consists of a gas-filled chamber with two electrodes: an anode (positive electrode) and a cathode (negative electrode). When ionizing radiation, such as alpha particles, beta particles, or gamma rays, passes through the gas, it ionizes the gas molecules, creating positive ions and free electrons.
