Radiation dosimetry was done by measuring free radicals induced in synthetic nano-structure hydroxyapatite (HAP) using EPR method. The HAP samples were synthesized via fluid body simulated method and were irradiated at different dose intervals and subsequently subjected to the EPR measurement. The effects of some EPR parameters were investigated as well. Variations of EPR signal intensities were constructed as peak-to-peak signal amplitude and were compared with alanine and bovine bone samples for two different dose ranges of Gy and kGy from dosimetric point of view. The results were shown that the HAP samples were more practical for doses in Gy range. At kGy range doses the bone sample and alanine dosimeter shows a better EPR responses.
