Popis: | 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 γ-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 µm.), 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. |
