Presented work deliberate the dosimetric impact of low absorbed dose in modified borate bioactive glass as utilization for such newly studied material. The particle size impact, glow curve, relative response to different doses, and dose fading impact was examined as thermoluminescence (TL) properties moreover. Thermoluminescence investigations of borate bioglass containing copper oxide irradiated by c-ray demonstrated a conspicuous TL glow peak maximum at 353 °C. The TL emission peak due to defects identified with the host material. The outcoming results are concerned with their uses in low dose dosimetry. The outcoming showed that the ideal grain size is extended between 53 and 106 lm.), respecting to glow peak of borate bioactive glass after gamma irradiation from gamma radiation cobalt source, three unresolved glow peaks was founded. The linear relationship response curve in the portion runs from 0.1 up to 1.5 Gy. The absolute TL-signal seems to be constant through 30 days of storage of the modified samples. Peaks activation energies were calculated through TL kinetics in deep traps, which recommended store the TL-signal. The low detected with a threshold value (0.01 Gy) fusing with this strategy represented as a good radiation sensitivity making it permissible to use for individual accidental retrospective. However, in the case of a personal dosimeter, Good and helpful data can be gotten on. Treatment would then be able to be founded on this data moreover.

1 Introduction One of the most important roles for bioactive glass their ability to support the revascularization process, osteoblast adhesion of connective tissues such as bone and muscle stem cells. Incorporation of trace elements in the glass network improving its properties, which have a good role in bone repair [1]. But the most important feature is how to increase the antibacterial properties of BG and how to be a benefit in different therapeutic uses [2, 3]. Progress in fabricating dense biomaterials with trace elements doped (e.g. Zn, Sr, Mg, and Cu) and their effect of these doped elements on biological performance are investigated and discussed in full detail [4]. Copper oxides among dopants are the promising host material because of its radiation sensitivity, thermal and chemical stability, high b
