This is a very detailed presentation on radioactive iodine and Graves’ Disease, presented at the Graves’ Disease and Thyroid Foundation’s 2011 Patient & Family Conference, November 5, 2011 by:

Dr. Anca Avram
Assistant Professor of Radiology
Director, Nuclear Endocrinology and Radiotherapy Section, Division of Nuclear Medicine/Radiology
University of Michigan Medical Center, Ann Arbor, MI

Take special note around 31 minutes into the presentation Dr. Avram points out the dangers of LOW-LEVEL exposure to children.  This is the risk that children and pregnant women have to worry about when coming into contact with I131 contamination.  This is why it is so important to properly clean up the isolation area.  The I131 may have left the patients body in 2-5 days, but any contamination left behind, will still be there for many weeks, unless you remove it.  The best way to remove I131 contamination is with Bind-It™.
