Abstract:
A radiation monitor includes an ionization chamber for detecting radiation that passes into the ionization chamber. The ionization chamber generates a current flow in response to the detected radiation. An electrometer is electrically connected to the ionization chamber for measuring the current flow generated by the ionization chamber. The electrometer is operable in a plurality of modes based on a magnitude of the current flow generated by the ionization chamber. A method of measuring current flow through an electrometer of a radiation monitor is also provided.
