Abstract
A radiation level measuring system having a Geiger-Muller gas ionizing tube as a detector. The inherent dead-time of the Geiger-Muller tube that follows a discharge pulse is compensated by the pulse counting electronic measuring circuit. A signal pulse of varying duration is formed from the detector output pulses in a manner that corrects for this dead-time. Measurement of this generated signal pulse duration give the actual radiation level that would be measured if the detector dead-time did not exist.
