Supervision of I-125 Production at the Center of Radioisotope and Radiopharmaceutical

The production of I-125 is one of the many research conducted at the Center for Radioisotope and Radiopharmaceutical. The supervision of I-125 production ia aimed in to managing an acceptance of external radiation doses of radiation by workers who engaged in the production of I-125 as dissolution and purification process of I-125 give a certain radiation exposure to the operator. According to the work instruction for preparation of I-125. The process has to closely monitored and supervised by Radiation Protection Officer (PPR). The production process of I-125 usually involves four radiation workers and one PPR. The acceptance of external radiation doses during the production process of I-125 was recorded was the PPR by using digital pen dose and radiation exposure rate was monitored by using survey meter. The acceptance of external radiation dose found was then compare the acceptance of external radiation dose from the TLD-badge reading and also to the dose limit value established by the monitoring board (BAPETEN). The acceptance of external radiation doses in the production of single batch of I-125 was found to be below the dose limit value (NBD) defined by BAPETEN. (author)
