Responses were tabulated from respondents who reported that they were &gt;18 yo, had at least one tx of 131I for DTC, and were responding regarding their last 131I tx.Results Of 621 respondents, 595 reported an attempt to pass through a public facility security checkpoint. Of these 595 pts, 55(9.2%) were detected to be radioactive, and 43 respondents noted that the location(s) were an airport 15(35%), border crossing 14(33%), government building 8(19%), shopping mall 3(7%), train station 2(5%), and steel recycling plant 1(2%). Several pts were detained more than once. Of 47 respondents, the SAs questioned 81%(38), allowed 27(57%) to proceed without a change in travel plans, requested documentation of the therapy from 26(55%), rescanned 26(55%), called a member of the treating team for 8(17%), “strip” searched 2(4%), detained 3(6%) such that a change in travel plans were required, and/or detained and prohibited continuation of travel for 2(4%). Of 47 respondents, they were detained from &lt;30 min 27(57%), 30-&lt;60 min 10(21%), 1-&lt;1.5 hrs 7(15%), 1.5- &lt;2hrs 1(2%), 2-3.5 hrs 0(0%), &gt; 4 hrs 2(4%).Conclusions Public detection of radioactivity after 131I tx occurred in 9.2% of pts in a variety of security checkpoints. Travel inconvenience is not infrequent and may require altering travel plans. Physicians should take steps to assure that pts not only have appropriate documentation of their I-131 tx with them, but also have instructions regarding how the SAs may verify the pts’ 131I tx with one of the members of the treating team.
