THE ADDITION OF AUTOMATIC TEMPERATURE AND PRESSURE SENSORS TO UNDERWATER GAMMA SPECTROMETER
Abstract
Radioisotope gages to measure temperature and pressure were incorporated into the deep underwater gamma spectrometer. With this change underwater radiation spectra can be related to other oceanographic measurements. The radioisotopes, 204-T1 and 57-Co, are mounted on conventional sensors, so that the radiation intensity reaching the detector is a function of temperature or pressure. Energy analysis separates the gage counts from each other and the environmental radiation. Only 5% of the energy scale is used for these gages. If environmental spectra were not required, this technique could be expanded to accommodate 20 gages on 1 detector.
