The radioluminescence (RL) and thermoluminescence (TL) properties of both KMgF3:La and K2YF5:Pr3+ compounds have been investigated in order to evaluate their use for real time and in-vivo dosimetry in radiotherapy. The results are compared to those obtained employing LiF:Mg,Ti. The experimental data shows that the compound having the higher TL signal has the lower RL signal, and vice versa, i.e., KMgF3:La bears the highest TL signal and the lowest RL signal, while K2YF5:Pr3+ bears the highest RL signal and the lowest TL signal. LiF:Mg,Ti shows RL and TL signals in between.3:La and K2YF5:Pr3+ compounds have been investigated in order to evaluate their use for real time and in-vivo dosimetry in radiotherapy.
