Uncombined (elemental) iodine is mildly toxic to all living things. The artificial radioisotope 131 I (a beta emitter ), has a half-life of 8.0207 days. Iodine-131 is used for unsealed source radiotherapy in nuclear medicine to treat several conditions. It can also be detected by gamma cameras for diagnostic imaging, however it is rarely administered for diagnostic purposes only, imaging will normally be done following a therapeutic dose.
