Maybe. According to the product brochures of one particular manufacturer of airport xray scanners, articles receive an average dose of 0.1 mR per exam. <http://www.controlscreening.com/Airport-Security-X-Ray-Scanner-machines.htm> An article would have to receive 10x this dose to match the FAA 1.0 mR limit (the limit after which the airport must put a sign saying that the machine may affect your highspeed film). It says that there is a "high penetration" mode that the operator can select, but it does not say how much it increases output. Whatever it is, I'm guessing it can't be more than 5 times normal penetration. So for me, it's not worth the inconvenience to myself, the screeners, and the other passengers waiting in line. When we all have our EOS 2010 1-VDS digital cameras, all of this will be moot. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
