I have to wear a &quot;life sustaining medical device&quot; (as printed on it and the &#x27;airport&#x27; card I was given).  The manufacturers are very, very explicit that the unit <i>will</i> be damaged by these scanners and that under no circumstances will they entertain any claim if it is.  The old-fashioned metal detector is OK for the brief exposure but will set it off and force a manual pat-down.  The x-ray baggage scanner is also a total no-no (but given it&#x27;s implanted, that would tend to involve me going through it too).<p>Opting out was practically encouraged last time I went via EWR - the woman doing the pat-downs seemed to be on training to do them, so they were funneling people to her rather than the scanners.<p>I see argument in some comments that the risk to a pregnant woman may not be so large (I have no idea), but there are many people with medical devices who could be seriously harmed by a mandatory policy.<p>If device manufacturers are so clear that the devices are not designed to be subjected to EMF from these scanners, will the TSA be replacing devices and compensating people ?<p>The security theater just got officially dangerous (ok, more dangerous than before).
