Spear, W G

A scintillation, portable, transistorized gamma energy analyzer was developed, designed, and fabricated in experimental form. It performs satisfactorily, utilizing the gamma photoelectric effect, in gamma radiation field levels from 0.01 to 1.0 mr/hr. Adjustments permit operation in other field strengths. The experimental instrument weighs seven pounds and the battery life for continuous operation is about 250 hours. As presently adjusted, the gamma energy span on the 10-turn dial is from about 100 kev to 1.5 Mev with a minimum stable window width or gamma energy delineation of 10 to 20 kev thereby giving good energy resolution. By utilizing one adjustment, the gamma energy span may be moved to as high an energy as desired. The system resolution, using Cs/sup 137/ source was found to be about 13 per cent, which is adequate for the use for which the instrument is intended. (auth)
