Abstract
Iodine capsule therapy was used to prevent recurrence of thyroid cancer. Hemodialysis patients receiving iodine capsule therapy require blood purification therapy in an RI room, but the method of administration has not been established, and there are few reports of such therapy in Japan. In this study, radiation dose before and after admission to the RI room was investigated in two maintenance hemodialysis patients who received iodine therapy after total thyroidectomy; both patients met the criteria for radiation dose exit after two hemodialysis treatments. Radiation contamination of the staff was also low, indicating that the treatment was performed safely. We report the results of the survey and some points to keep in mind when performing blood purification therapy in a radiation area.
