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