Which one of the following describes the reason for the high sensitivity of a gas-filled radiation detector operating in the Geiger-Mueller region?

A. Any radiation-induced ionization results in a large detector output pulse.

B. Geiger-Mueller detectors are longer than other types of radiation detectors, resulting in greater detector surface area.

C. The detector output is inversely proportional to the applied voltage within the Geiger-Mueller region.

D. High detector voltage allows differentiation between the various radiation types.
