I have concerns about radiation exposure from TSA’s new airport scanners. According to a letter sent last April to the President’s Office of Science and Technology Policy, there is significant concern about the health risks associated with the full body scanners being implemented at U.S. airports. The co-signers were David Agard, PhD, John Sedat, PhD, (emeritus), and Robert Stroud, PhD, all professors of biochemistry and biophysics, and Marc Shuman, MD, professor of medicine (hematology/oncology). The professors finally received a response to their letter during the first week of November, but they have not yet released the text of the response.
Here is a link to the UCSF Public Affairs media release about the letter: http://news.ucsf.edu/news-briefs/details/ucsf-scientists-speak-out-against-airport-full-body-scans/
