Abstract

The appts. is used for measuring radioactive radiation. A solid state detection unit is exposed to the radiation and the signal is integrated in order to provide a voltage proportional to the charge liberated by ionisation. This voltage is used to trigger a threshold triggering circuit when its value exceeds a predetermined threshold. The detection unit comprises several dissimilar detectors which are exposed simultaneously to the radiation. Their outputs are electrically treated to compensate for their individual responses s.t. the sensitivity of the method is independent of the incident radiation spectrum.
