EXPERIMENTAL AND RESEARCH WORK IN NEUTRON DOSIMETRY
Abstract
The readout problem is discussed and the development is described of an engineering readout instrument which is an improvement over the earlier prototype model and provides an accurate means of making radiation measurements on the radiac detectors designated as DT-236 (XE-1)/PD. Consideration was given to the measurement of 2 parameters, carrier lifetime and forward resist-ANCE, BOTH OF WHICH ARE FUNCTIONS OF THE TOTAL RADIATION EXPOSURE OF THE DETECTOR. The objective was to develop an engineering model of a readout device for measuring either lifetime or forward resistance. Tests indicated that the engineering model of the readout instrument developed is capable of measuring the forward voltage drop across the radiac detector to an accuracy of about + or - 5 per cent under roomtemperature conditions. The radiation exposure of a given detector can therefore be determined from suitable voltage-radiation calibration curves for the detector type. (Author)
