Radiation protection principles for radioiodine therapy

摘要

In Germany, approximately 30,000 treatments with radioiodine are performed yearly in patients with benign or malignant thyroid diseases. These are carried out generally in specialized therapy wards which are equipped with radiation protection facilities. Ambulant (fractionated) radioiodine treatment is not permitted in Germany. More recently, the situation has been that the discharge of patients is permitted, when they have spent a stay of at least 48 hours in the ward without the dose rate exceeding 3.5 u Sv/year (this correlates to a residual activity in the body of the patient of 250 MBq).
