OverTheGeicoE writes "TSA employees at Logan International Airport believe they have identified a cancer cluster in their ranks, according to documents obtained under the Freedom of Information Act and released by the Electronic Privacy Information Center. They have requested dosimetry to counter 'TSA's improperly non-monitored radiation threat.' So far, at least, they have not received it. The documents also reveal a paper from Johns Hopkins that essentially questions whether it is even safe to stand near an operating scanner, let alone inside one. Also, the National Institute of Standards and Technology says that the Dept. of Homeland Security 'mischaracterized' their work by telling USA Today that NIST affirmed the safety of the scanners when in fact NIST does not do product safety testing and never tested a scanner for safety."
