That is, it claims that the machines are perfectly safe "when they're working properly." But as AOL's senior public health reporter discovered, "the TSA offers no proof that anyone is checking to see if the machines are 'working properly.'" Well, it pretends to offer proof, in saying that a variety of groups, including the FDA, the US Army, Johns Hopkins Applied Physics Lab and something called the Health Physics Society all work with the TSA to make sure the devices are safe. But, Schreiber contacted all the groups listed and found that it's not what you'd think. Those groups do not make sure that the machines are properly maintained and calibrated. Basically, it sounds like most of these groups tested or examined one or a small number of these machines -- often not the ones actually installed at the airport, to see if, conceptually, the machines are safe. But none of them have anything to do with making sure the machines are maintained and calibrated safely, such that passenger safety is not put at risk. In fact, one of the groups listed -- the Health Physics Society -- noted that the TSA actually refused to provide data that the TSA collects on radiation exposure from the scanners.
So despite the fact that scientists are quite concerned that ill-maintained scanners or mis-calibrated scanners can cause serious health problems for people, it does not appear that the TSA has any serious specific program to guard against this. So, the machines are safe, if they're working properly, but no one's making sure that they're really working properly -- other than the TSA, who doesn't give much details into what's actually being done to make sure that the machines are, in fact, calibrated and maintained properly.
