Abstract
Two peaks were found in the high temperature region for LiF thermoluminescent phosphor TLD-100. The total area of these two peaks increased with dose to a saturation value at about 4 Mrads. By extrapolation, a threshold dose of 1 krad was required to produce these two peaks. An investigation, using a thermal annealing technique, showed that these two peaks do not fit the Randall and Wilkins model. Evidence from optical absorption showed that these two peaks are probably connected with V-centres (hole traps). An attempt has been made to correlate the supralinearity and sensitization behaviour to these two peaks.Keywords
