Abstract

An attempt is made to predict/interpret theoretically the experimentally measured values of f(D) and S(D_s)/S_o for composite peak 5 in TLD-100, using the Unified Interaction Model (UNIM) with identical values of the UNIM parameters for both sets of experimental data. Although an excellent fit can be obtained to the experimental f(D) data over the entire dose region where f(D) is greater than unity, i.e. from 5 Gy to several thousand Gy, a satisfactory fit to both sets of data is found to require different values for at least one of the parameters. The lack of success in fitting f(D) and S(D_s)/S_o with the same values of all the parameters, suggests that the sensitisation anneal (particularly the duration of the anneal) may somehow change the structure (S_LC) and/or the total number of available LCs in an unknown manner.
