The thermoluminescence (TL) characterizations of γ‐irradiated KCl:Dy phosphor for radiation dosimetry are reported. All phosphors were synthesized via a wet chemical route. Minimum fading of TL intensity is recorded in the prepared material. TL in samples containing different concentrations of Dy impurity was studied at different γ‐irradiation doses. Peak TL intensities varied sublinearly with γ‐ray dose in all samples, but were linear between 0.08 to 0.75 kGy for the KCl:Dy (0.1 mol%) sample. This material may be useful for dosimetry within this range of γ‐ray dose. TL peak height was found to be dependant on the concentration (0.05–0.5 mol%) of added Dy in the host.
