          Abstract

          The thermoluminescence response of Dysprosium doped hydroxyapatite samples with different mol percentage of 0.5, 1 and 2 were studied and compared with the pure hydroxyapatite. The samples were objected to 60Co gamma rays irradiation with doses of 100 mGy to 10 Gy. The main peak in the sample glow curves were obtained at 310 °C. The sensitivity of the 1 mol% Dy doped hydroxyapatite samples show the highest thermoluminescence response. Fading behavior of the irradiated samples was also studied. The experimental results show that the synthetic Dy-doped hydroxyapatite obtained by the hydrolysis method may be used in gamma radiation dosimetry.

          Kurzfassung

          Die Thermolumineszenzeigenschaften von Dysprosium dotierten Hydroxylapatit-Proben mit verschiedenen Mol-Prozenten von 0.5, 1 and 2 wurden untersucht und verglichen mit reinem Hydroxylapatit. Die Proben wurden mit 60Co Dosen von 100 mGy bis 10 Gy bestrahlt. Der Glowkurven-Hauptpeak der Probe wurde bei 310 °C erhalten. Die mit 1 mol% Dy dotierten Hydroxylapatit-Proben zeigen das höchste Ansprechvermögen. Das Fading-Verhalten der bestrahlten Proben wurde ebenfalls untersucht. Die experimentellen Ergebnisse zeigen, dass das mittels der Hydrolysemethode erhaltene synthetische Dy-dotierte Hydroxylapatit in der Gammastrahlendosimetrie verwendet werden kann.
