Which detector is confined for use in detecting radiation where the exposure levels are below 2000 mR/hr?

Question

Quizplus · Accepted Answer

The recovery time for the anode to recharge after an event is about 100 µsec.Additional events that occur during this time interval (also called the deadtime) prolong the recovery and can even stop the detector from operating when the exposure rate is too high.As a result, GM detectors are confined to use in areas where the exposure level are below 2000 mR/hr.
