Radioiodine

Paul A. Bekeris has written:

'The sorption of radioiodine onto zinc and vinyl based containment paints'

Radioisotpes are used to treat the thyroid, especially for those who have hyperthyroidism or Graves' disease. Radioiodine is swallowed by a patient and then it is absorbed by the thyroid. The radioiodine eventually kills thyroid cells. This helps patients with an overactive thyroid by slowing down the production of thyroid hormones.
