A stable radioctive medicine which comprises a radioactive iodine-labeled compound and a deiodination inhibitor selected from the group consisting of α-thioglycerol, sodium hydrogensulfite, sodium pyrosulfite, cysteine hydrochloride, sodium edetate, sodium thioglycolate, and butylhydroxyanisol. This medecine stably retains the radioactive iodine incorporated in the radioactive iodine-labeled compound and undergoes no decrease in radiochemical purity. It is hence extremly useful in the field of radiotherapy.
