My prof gave this kind of situation: "Radioiodine therapy has been frequently used to help treat malignancies in the thyroid gland. Assume that a patient was administered 9GBq of I-131, and 27 hours later the patient suffered a cardiac arrest and died. If you were the medical physicist of the hospital. what recommendation would you give to the people involve in the autopsy like the embalmer..?" so anyone have an idea...?
