Abstract
IMPROVEMENTS OF LASER-HEATED THERMOLUMINESCENCE THAT ARE DESIGNED TO MAKE DOSIMETRY OF MIXED GAMMA-FAST NEUTRON FIELDS FEASIBLE WILL BE IMPLEMENTED AND TESTED. THESE ADVANCEMENTS IN LASER HEATING TECHNOLOGY ARE EXPECTED TO INCREASE THE FAST NEUTRON THERMOLUMINESCENCE SENSITIVITY SUFFICIENTLY TO MAKE TLD OF FAST NEUTRONS A CONVENIENT METHOD FOR ROUTINE PERSONNEL DOSIMETRY. THIN LAYER DOSEMETERS WILL BE FABRICATED USING COMMERCIAL TLD POWDERS AND HIGH TEMPERATURE POLYMERS HAVING A LOW HYDROGEN CONTENT. HYDROGENOUS RADIATORS COVERING PART OF SUCH A DOSEMETER WILL EXCITE THE TLD POWDER IN THE LAYER VIA NEUTRON-GENERATED KNOCK-ON PROTONS. NEUTRON-GAMMA DISCRIMINATION WILL BE PROVIDED BY COMPARISON OF TL SIGNALS MEASURED FROM THE COVERED AND UNCOVERED PARTS OF THE DOSEMETER.
