EXPERIMENTAL AND RESEARCH WORK IN NEUTRON DOSIMETRY: PHASE II. Final Summary Report, March 1-April 30, 1961

The readout problem is discussed, and the development is described of an engineering readout instrument that provides an accurate means of making radiation measurements using radiac-type detectors. Consideration was given to the measurement of 2 parameters, carrier lifetime and forward resistance, 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 resistanxe. Tests indicated that the model of the readout instrument developed was capable of measuring the forward voltage drop across the radiac detector to an accuracy of about plus or minus 5 per cent under roomtemperature conditions. The radiation exposure of a given detector can therefore be determined from suitable voltageradiation calibration curves for the detector type. (auth)
