Rare earth doped magnesium tetraborate (MgB4O7) has gained significant attention in the last decade as a prominent dosimetry material in thermally stimulated luminescence (TL) and, more recently, as a potential optically stimulated luminescent dosimeter. This report aims to provide a comprehensive review of the state of the art in doped MgB4O7 and to analyze the lessons learned from over 50 years of material development to assist the younger researchers in the field of materials for ionizing radiation dosimetry. An overview of the dosimeter properties when different dopants and charge compensators is described. •Review of the state of the art in doped MgB4O7 for ionizing radiation dosimetry.•Several synthesis methods can be used to produce MgB4O7.•The first reports on MgB4O7 doped with rare-earth elements dates to the 1970s but are still actively being produced.•MgB4O7:Ce,Li is a strong candidate as the first Optically Stimulated Luminescence (OSL) dosimeter for neutrons.
