Description/Abstract:
THIS PROJECT WAS CONDUCTED TO MEASURE THE INITIAL GAMMA DOSE AS A FUNC TION OF DISTANCE FOR SHOTS STAR FISH PRIME, BLUE GILL TRIPLE PRIME, AN D KING FISH. TO ACCOMPLISH THESE OBJECTIVES, THE GAMMA DOSE WAS MEASU RED BY FILM BADGES, GLASS MICRODOSIMETERS, COBALT-ACTIVATED BOROSILICA TE GLASS, CALCIUM FLUORIDE THERMOLUMINESCENT DOSIMETERS, AND FORMIC AC ID CHEMICAL DOSIMETERS. PROJECT 2.2 SUCCESSFULLY MEASURED THE GAMMA D OSE VERSUS DISTANCE FROM SHOTS STAR FISH PRIME, BLUE GILL TRIPLE PRIME , AND KING FISH. THE GAMMA DOSES FROM ALL EVENTS WERE WITHIN DESIGNED EXPERIMENTAL ERROR AND PRECISION. THE MEASURED GAMMA DOSES FROM THE THREE EVENTS SCALED WELL AS DOSE PER KILOTON VERSUS DISTANCE. THE THE ORETICALLY PREDICTED DOSES WERE [ ] THAN THE MEASURED DOSES. THE INCIDENT THERMAL NEUTRON FLUX ON THE POD BACKPLATE FOR SHOT BLUE GILL TRIPLE PRIME AS ESTIMATED BY THIS PROJECT AGREED IN ORDER OF MAGN ITUDE WITH THAT REPORTED BY PROJECT 2.1. BY THE USE OF COBALT-ACTIVAT ED BOROSILICATE GLASS PLATES AT TWO DIFFERENT LOCATIONS IN THE INSTRUM ENT PODS, PROJECT 2.2 WAS ABLE TO MEASURE THE DIFFERENTIAL THERMAL NEU TRON FLUX CREATED BY THE THERMALIZATION OF FAST NEUTRONS BY THE POD MA SS. THE FORMIC ACID CHEMICAL DOSIMETER FAILED TO PROVIDE RELIABLE GAM MA DOSES DUE TO ITS HIGH DOSE-RATE DEPENDENCE. THE CALCIUM FLUORIDE T HERMOLUMINESCENT DOSIMETER PROVIDED READINGS THAT WERE CONSIDERABLY HI GHER THAN THOSE MEASURED BY THE OTHER DETECTORS. FURTHER RATE DEPENDE NCE STUDIES ARE NECESSARY TO EXPLAIN THIS DISCREPANCY.
