Aims: Based on recent studies, it was indicated that gold (Au-197) nanoparticles could be safely prescribed and used to enhance the absorbed dose during radiation therapy. Subjects and Methods: We evaluated the samarium-153 (Sm-153) radiopharmaceutical and Au-197 and Sm-153 radiopharmaceutical absorbed dose rate by means of the Monte Carlo technique in prostate cancer. Results: The results show that absorbed dose rate in entire prostate volume due to 20 mCi of Sm-153 radiopharmaceutical is 27.339 μGy/s, 48.837 μGy/s, and 76.176 μGy/s for γ-interaction, β¯ particle interaction, and γ+β¯ interaction, respectively. The results in the exterior of the prostate for β¯ interaction, β¯ particle interaction, and γ+β¯ interaction were 20.971 μGy/s, 1.110 μGy/s, and 22.081 μGy/s, respectively. Conclusions: The calculation results for Au-197 and Sm-153 radiopharmaceutical show that the absorbed dose rate in entire prostate volume 3% was increased and undesirable dose value in exterior of prostate 7% was decreased.
