In consideration of the changes to the KI PAG recommendations, you may wish to consider the following: Before KI became so readily available (in the late 1980s), some studies were done on the efficacy of topical application of tincture of iodine and/or povidone-iodine solution (Betadine) to the skin as a means of providing a loading of stable iodine to saturate the thyroid and prevent or reduce the potential uptake of the radioiodine. There is an established scientific basis for the success of that method for protection of the thyroid gland. As the method relies solely on the topical application of first-aid treatments typically found in most homes and having no particular shelf-life problems, it may provide the public with an alternative to worrying about when and whwere to get and take KI in an actual emergency. Consider adding a footnote to that effect in the document. I have more detailed guidance, if you are interested.
