Fiber optic dosimetry (FOD) technique offers a simple way to perform real time and in-vivo dose rate assessment in radiotherapy with high spatial resolution [1]. So far plastic scintillators and C-doped aluminum oxide (Al2O3:C) are the most promising converters of the ionizing radiation to light (radioluminescence, RL) from the viewpoint of application for this technique. The interest in this research area prompted the development of alternative RL materials that better meet the needs of technological applications. In the present work we investigate the RL emission, RL spectra and phosphorescence (i.e. afterglow) of LiMgF3 doped with Eu, Ce, Tl, and Lu. The effective atomic number of this material is near to tissueequivalent with an Zeff = 9.86.
