Abstract: The purpose of this study was to analysis and evaluate the organ at risk (OAR) doses estimated based on International Commission on Radiation Units and Measurements (ICRU) reference-point in patients with cervical cancer treated with high-dose-rate (HDR) Intracavitary brachytherapy (ICBT) in Radiation and Isotopes Center Khartoum (RICK). This study was conducted at Radiation and Isotopes Center Khartoum (RICK). The study included 90 cases of patients with cervical cancer. All patients received a therapeutic dose in the Department of brachytherapy of 9 Gy. In addition, the dose was measured for the bladder and rectum and the results were analyzed and evaluated. Patients who exceeded the dose of rectum they had the permissible dose of the total number of patients were 33.3 % & patients who exceeded the dose of Bladder they had the permissible dose of the total number of patients were 14.4 %. In this study, it was found that the dose to OARs was higher in some cases received treatment in (HDR) Intracavitary Brachytherapyof the dose of OARs based on the (ICRU). It is important to keep the dose as low as possible to avoid the side effect of radiation. Taking into account that the treatment was in two dimensions. This means that the study was based on the measurement of potions for points and not for the whole size so it is preferable to use a three-dimensional treatment technique.
