Abstract

A three terminal ionization chamber includes a first electrode coupled to a bias voltage source spaced apart from a second electrode coupled to ground. A third terminal is provided which is positioned between the first and second electrodes. Measurement circuitry may be coupled to the third terminal to measure charge indicative of the amount of radiation incident to the chamber.
