Abstract
Abstract This paper deals with the characteristics of TLD-6LiF: Mg, Ti (TLD-600) to be used as an ultraviolet radiation dosimeter based on the photo-transfer thermoluminescence method. Thermoluminescent dosimeters were pre-irradiated with D2O-moderated 252Cf neutrons instead of gamma rays in order to increase the growth efficiency of residual thermoluminescence to be transferred to UV irradiation. Thermoluminescent parameters, trap depth (E), frequency factor ([sgrave]) and kinetic order for neutron-irradiated TLD were studied by both glow curve shape analysis and variable heating rate methods. For the 203°C peak, the E values are 1.36 and 1.31 eV and [sgrave] values are 1.5 × 1013 and 4.2 × 1012 s−1 respectively for these two methods. For the 263°C peak, the E values are 1.58 and 1.76 eV and [sgrave] values are 3.8 × 1013 and 2.1 × 1015 s−1 respectively. Kinetic orders of both peaks were close to unity. The parameters obtained for peak 3 are comparable with that obtained by other investigators. The metho...
