【 摘 要 】

In this work, synthetic nano-structure hydroxyapatite samples were doped bycarbonate ions with 80 keV of energies during different times of 4, 8, 16,and 24 minutes using an ion implantation device. All the samples wereirradiated with the 60Co gamma ray source at different absorbed doses of 5,10, 20, and 50 kGy and subjected to electron paramagnetic resonancemeasurements, subsequently. The electron paramagnetic resonance signalintensities were constructed as a function of radiation dose and werecompared with the results of non-implanted one, and were studied fromdosimetric point of view. The obtained results show a considerable incrementin electron paramagnetic resonance signal intensity of the samples which wereimplanted for 24 minutes.
