Abstract
Self-calibrating radiation detection apparatus comprising a detector element and calibration apparatus for maintaining a generally constant response of the detector element to a predetermined radiation input notwithstanding changes in the level of background radiation sensed by the detector element. There is also provided control apparatus for operating a plurality of radiation detectors including apparatus for disabling the output of the detectors in response to a continuing radiation input of predetermined duration.
