摘要: Computerized glow curve convolution (CGCD) has been used to study the thermally induced room-temperature fading of both annealed and unannealed LiF:Mg, Ti following gamma ray, thermal neutron alpha particle irradiation. The authors confirm anomalous growth peak 4 due trap conversion in types material. However, they find no evidence for 5 either material any radiation studied. Their results similarly not details differences previously observed ray irradiation point great difficulty encountered arriving at a universal characterization when peaks 2 3 or fraction thereof are included thermoluminescent signal. On other hand only is employed dosimetric measurements (via CGCD) well behaved rate (-5.5+or-2.6)% (ISD) per month all obtained. They believe that these convincingly demonstrate advantages using where corrections importance.
