Abstract
The technique of UV light bleaching for the re-estimation of the absorbed dose of radiation received by LiF thermoluminescence dosimeters was extended to the extruded ribbon and PTFE disc form of dosimeter. The threshold of detection for the re-estimation of absorbed dose was 1.1 rad for the PTFE disc dosimeters and 2.8 rad for the extruded ribbon dosimeters. By raising the temperature of the dosimeter during bleaching the threshold for re-estimated absorbed doses may be substantially reduced. The optimum temperature was 80.degree. C and the practical threshold for the re-estimation of absorbed dose using a PTFE disc dosimeter was determined as 750 mrad.This publication has 1 reference indexed in Scilit:
