Therapeutic studies in hyperthyroidism; use of radioactive iodine

Of 112 patients with hyperthyroidism who were treated with radioactive iodine, 110 were relieved of the disease. Nine had transient hypothyroidism. Twelve had permanent hypothyroidism. No other adverse effects that could be attributed to radioactive iodine were noted.     

The significance of extrathyroidal radioactive iodine accumulation and secretion in clinical pathology

Summary The uptake and the distribution of ¹³¹I^– injected intravenously into rats was followed up by whole body autoradiography. Extrathyroidal accumulations with some interest for clinical pathology were found in the nose, the hair follicles and the mucous cells of the stomach.     

The safe use of radioactive isotopes in teaching experiments

Radioisotopes have played major roles in the investigation of biochemistry and physiology and many courses now include some instruction in the practical use of these materials. This article briefly discusses some of the dangers involved in the use of radioisotopes and includes a comprehensive list of precautions and laboratory rules for use during radiobiology experiments.
