IMPROVED FABRICATION TECHNIQUES FOR LITHIUM-6 FLUORIDE-TEFLON AND LEAD SHIELDS FOR GAMMA DOSIMETRY

摘要

This report reviews the development of fabricating lithium-6fluoride-Teflon (Li6F-Teflon) and lead shield assemblies to provide inexpensive dosimeters for gamma radiation. The newly developed techniques include molding, in one pressing, the complete Li6F-Teflon shield with a center hole for silver-activated phosphor glass rod detectors;lead foil serves as the lead source for the shield assembly. A description of the equip¬ment, as well as the automation portion of the pressing procedures, is also presented in this study.
