Abstract:

[Background] The 252Cf brachytherapy is mainly used for cervical cancer endovascular radiotherapy. [Purpose] Radiation therapy will inevitably cause radiation damage to nearby organs. Therefore, it is necessary to evaluate the radiation damage of cervical cancer patients during radiotherapy. [Methods] This article is based on the radiation therapy of 252Cf cervical cancer in a hospital, and theoretical calculations and practical tests of dose field distribution in air and water by 252Cf, and compared with the tolerance limits of uterus, rectum, bladder, ovary and other organs. [Results] By comparison, it is concluded that in the process of cervical cancer treatment, organs such as the rectum, bladder and ovary are also affected by large radiation in addition to damage caused by high doses of irradiation. [Conclusion] In order to reduce the radiation damage of cervical cancer patients, the optimal irradiation time under different source activity was calculated.
