Abstract:
Objective: To evaluate the radiation protection and performance test for the 192Ir brachytherapy apparatus. Methods: According to the national standard, radiation protection and its various properties of the 192Ir brachytherapy apparatus were tested. The radiation leakage dose of the 192Ir brachytherapy apparatus and the radiation scattered dose of the surrounding environment were tested with the ion chamber survey meter 451P. The activity of 192Ir radiation source was calibrated with the well chamber HDR1000 Plus. Results: The radiation leakage and scattered dose of the 192Ir source storage device and the surrounding environment are far below the national standard. The deviation of the activity calibration for 192Ir source is-2.07%, accordance with national standard±5%. Conclusion: Radiation protection and its various properties of the 192Ir brachytherapy apparatus should be regularly monitor for assuring the quality of the brachytherapy.
