Abstract
A radiation dose rate monitor system includes an emitting electrode configured to be impinged by radiation radiation; a collecting electrode configured to form an electrical circuit with said emitting electrode, a current measurement device configured to measure a current through said emitting and collecting electrodes indicative of a dose of said radiation radiation, and a chamber enclosing a gas. Emission of secondary electrons from the emitting electrode provides a majority of the current.
