The use of high-dose rate brachytherapy for cancer treatment is increasing and the number of patients treated in Brazil is high, considering the number of existing equipments. However, the small number of equipments is a limiting factor that bring on a lot of pressure on the working routine. For this reason, a reevaluation of emergency procedures is not carried out in most centers. This paper describes the most frequent emergency situations and suggests a code of practice when errors do not allow the return of the radiation source to the shield and result in undesirable radiation exposure to the patient and staff in remote centers for brachytherapy. We suggest training, additional caution measures and quality control in order to minimize undesirable doses.
