I use a leadlined bag, available in a good retailer. The film is, after all, only ISO 400, and most xray-machines at the airport are said to not damage film up to ISO 1600, at least here in Europe. In the US, I have travveled throug Seattle Internatinal, Chicago O'Hare and San Franscisco International without damage. The X-rays on checked baggage is stronger, so handluggage is preferable. Don't let the airport personel inspect by hand, which means opening the containers, as this WILL ruin the film. Knut O - Norway, home of giants |

HIE infrared film
I just travelled through San Fran three weeks ago.
Handluggage xray machines damaged my tmax 400 (no leadbag). Will using leadbags cause airport personel to increase xray power to see whats inside? Is it worth using leadbags? What about couriering film only with "film-only" stickers? Please post your infrared experience here. Good luch with HIE.

HIE infrared film
I shoot mostly ASA 400. I past years, I passed my film around the scanner
and asked them to hand inspect it. In the last year or so with tightened security, I have been told repeatedly that up to 1000 or 1200 ASA film is safe for the hand luggage scanning. As a result, I have passed film through at least twice each roll (once each time on a round trip) and have seen no fogging I could detect. I have yet to try my HIE. Sam " |

Kodak makes no mention of problems with a pass or two through airport x-ray machines with 400 speed film, and I haven't had any problems with even higher speed B&W film. I wonder if there wasn't another cause that you have not connected. Will using leadbags cause airport personel to increase xray power to see whats inside? No. Except for some very rare types of machines, the power of the typical airport scanner cannot be adjusted by the operator. Is it worth using leadbags? That's up to you. Lead bags do not block out x-rays entirely, they only reduce the exposure. Domke, one of the major manufacturers of the bags, did some tests with the type of machine used for checked bags, and concluded that for a bag to be fully effective, it would be too heavy to be practical. Thus, the light weight bags available to consumers are a compromise. Keep in mind that the film's exposure to radiation is higher when you are actually in the aircraft at altitude than in the x-ray scanner. The scanners are only a small part of the problem. What about couriering film only with "film-only" stickers? Personally, I wouldn't bother, but some people prefer that with high speed film compared to the hassle of dealing with airport security personnel. I would worry about additional exposure to heat, if you are sending the film to someplace hot, and the film might sit in a truck somewhere, i.e. Phoenix in the summer. |

The film is, after all, only ISO 400, and most xray-machines at the airport are said to not damage film up to ISO 1600, at least here in Europe. I was simply repeating the warnings from Kodak. Infrared film seems to be more sensitive to x-rays than other types of film, so the "above ISO 800" rule doesn't apply. While Kodak suggests that ISO 800 film can be safely passed through the inspection machines a few times, they also state that no exposure to x-rays is considered safe for infrared film. That said, people have reported passing their infrared film through airport scanners without noticeable problems. Kodak might be being somewhat conservative in their recommendations, since they would be concerned about professionals who don't want to see anything that would affect the consistency of their results. The first effect that an airport scanner would have on the film would be a reduction in contrast, which would not be seen by someone simply looking for fog on the film, but would be seen by someone comparing similar photos taken on affected film and unaffected film. An amateur would not necessarily notice the contrast change on a few photos. |

I just travelled through San Fran three weeks ago. Handluggage xray machines damaged my tmax 400 (no leadbag). Why didn't you ask for hand inspection? I was at SFO in March and my request for hand inspection was handled very courteously and professionally. Took a while, and there are now a couple of security folks who know all about the inner life of a Hasselblad, but no problems at all. Basically all films were wiped for explosive 'sniffing' but freshly factory sealed films were taken for granted, no desires to look inside the sealed packaging. HIE is a bit of a pain here (no handling in daylight), but TMAX400 should have been no problem. Just allow enough time, I was there very early (for a flight back to .nl). Will using leadbags cause airport personel to increase xray power to see whats inside? Generally yes. Wilko |

SFO has a sign up that claims up to 1600 ASA is supposed to problem free. (or was it 1600ASA in Amsterdam and 3200ASA in SFO? I forgot). |

Thats what irks me about all of this new security. Much of it seems pointless. If I wanted to blow up a plane I don't care if my film (which isn't even film; its explosives) so I would simply send it through the machine. |
