Radiophotoluminescence (RPL) is a phenomenon in which new luminescent centres are induced in certain materials, typically insulators, following exposure to ionizing radiation. In ideal materials, these centers exhibit remarkable stability, remaining unaffected by ambient light or variations in environmental temperature. This stability makes RPL dosimeters advantageous over other dosimetric systems, as they provide reliable and reproducible measurements. Despite these benefits, the number of available RPL materials remains limited. In this work, Pb-doped magnesium borate glass samples were synthesized using the melt-quenching technique and their RPL properties were investigated. The material obtained shows photoluminescence and, after the X-rays irradiation, it is observed in the spectrum the increase in the emission in the 720-1000 nm range.
