A Study on Pipe-type Radioactive Wastes in the Iodine Ward

초록

Based on the fact that it is difficult to extract pure radioactive isotopes during the manufacturing process of the radioisotope, we conducted a study on the purity of 131I used in patients in clinical practice. Nuclear medicine treatment using I-131 is performed by being admitted to a dedicated ward. In the most commonly used method I-129 is for producing I-131 , present in 0.1 %. Therefore, the importance of the management of pipes arises. According to the calculation formula, in the case of I-131, the radioactivity does not increase after 60 days. However , if I-129 is present in 0.1 %, the radioactivity increases after 6 months. A similar result was also obtained when the pipes in the treatment room used for 8 years were measured. Therefore, the development of a pure I-131 generation method is currently required, and a realistic radiation safety management system such as applying the extraction technology of I-129 or enacting the regulations for the follow-up management of sealed pipes should be constructed as auxiliary methods.
