ALL SOLID-STATE INTEGRATING DOSIMETER

RECENTLY, RESEARCH AT SEVERAL GOVERNMENT FACILITIES HAS RESULTED IN SIGNIFICANT ADVANCES IN BOTH THE ELECTRONIC AND DETECTOR ASPECTS OF INTEGRATING RADIATION DOSIMETERS. ONE PARTICULAR APPROACH, THE LOS ALAMOS MULTIDETECTOR RADIATION MONITOR, IS A MICROPROCESSOR BASED INSTRUMENT, CAPABLE OF INTERROGATING SEVERAL DIFFERENT NUCLEAR DETECTORS SIMULTANEOUSLY. ALTHOUGH USING GEIGER TUBES FOR THE GAMMA AND BETA SENSORS, THIS DEVICE PROVIDES AN IDEAL FOUNDATION FOR AN ALL SOLID-STATE RADIAC. WE PROPOSE TO INCORPORATE SOLID-STATE GAMMA DETECTORS INTO THIS UNIT AS WELL AS A SENSITIVE SOLID-STATE SENSOR CAPABLE OF DETECTING FAST NEUTRONS. WE SHALL ALSO MODIFY THE LOS ALAMOS DESIGN TO ALLOW THE EXISTING SOLID-STATE ALPHA DETECTOR TO BE USED FOR BETAS. THE PHASE I PROGRAM WILL DEMONSTRATE THE FEASIBILITY OF MAKING AN ALL SOLID-STATE RADIAC. IN PHASE II A COMPLETE WORKING PROTOTYPE WILL BE DESIGNED AND CONSTRUCTED FOR TEST.
