A radioactive source such as the one shown in Fig. 1 would be inserted into the cervix of these patients, and after making sure that the radioactive source was correctly positioned, radioactive isotopes were manually injected into a designated space within the radioactive source. As shown in Fig. 1, three radioactive isotopes were placed in the middle tandem, and one in the ovoid on both sides (Fig. 1).

However, when we measured the level of radiation exposure during radioiodine therapy of the thyroid in which radioactive isotopes are still manually injected, we could see a peak in the radiation dose immediately after the injection of radioactive isotopes, which was followed by a gradual decrease, as shown in Fig. 2.
