Abstract

The thermoluminescence (TL) sensitivity to ionising (beta source) and non-ionising (UV) radiation on KCl:Eu2+ single crystals has been investigated. The different shapes of the TL glow curves allow us to detect specific peaks (over 220-250 °C) due to UV exposure that exhibit a negligible contribution associated with ionising radiation. The UV-induced TL emission could be deconvoluted into five groups of components peaked at about 120, 150, 210, 250 and 330 °C assuming first order kinetic processes. Dose saturation and linearity region have been determined for a wavelength of 254.7 nm. The effect of several cycles of UV irradiation processes on the linearity of the high energy ultraviolet KCl:Eu2+ dosimeter has been also studied to determine the potential reusability.
