  • Title: Energy dependence of the response of lithium fluoride TLD rods in high energy electron fields.
    Author: Holt JG, Edelstein GR, Clark TE.
    Journal: Phys Med Biol; 1975 Jul; 20(4):559-70. PubMed ID: 1187787.
    Abstract:
    The energy dependence of lithium fluoride dosemeters is a complicated function of energy as well as of cavity size. In the application of TLD to charged particle dosimetry, a cavity perturbation effect may exist even though the ratios of the mass stopping powers are constant over the energies encountered. This effect was investigated for lithium fluoride rods in electron fields ranging in energy from 2-5 to 20 MeV. A 13% change of TL response per unit of absorbed dose was measured over that energy range. A semi-empirical theory was developed to account for the cavity effect, using Burlin cavity theory as a starting point. The agreement between theory and measurement is satisfactory.
