Will Airport X-Ray Scanners affect undeveloped film?
Posted by eBestAgent in PHOTOGRAPHYMyth-buster #1
There are myths surrounding airport X-Ray security scanners. Many believe that it will either fog undeveloped films or leave undesired fan-shaped streaks. There are many photographers that are afraid to let their rolls of films go through the X-Ray scanners or even metal detectors.
It seems like everyone is using Digital Camera but there are many photographers and artists love to shoot with film cameras especially 6X6 medium formats and large formats.
Will Airport X-Ray Scanners affect undeveloped film?
Based on study conducted by International Image Industry Association (I3A) formerly Photographic and Imaging Manufacturers Association (PIMA), airport x-ray scanner produced no damage and difficult to notice any damage.
I3A conducted extensive testing at the FAA’s technical center using identical or similar airport security scanners that are used in U.S. and international airports. Color negative, color slides, and B&W films ranging various speeds of films from ISO 50 to ISO 3200. I wish that they included the infrared films but I couldn’t find any test regarding infrared films.
Based on the study, up 16 scans didn’t produce any damage to all films. High speed B&W films were slightly effected after 16 scans that are not noticeable to naked eye. But after 100 scans only the high speed ISO rated films show slight effects. It was impossible to see any add evidence of x-ray damage even the high speed ISO films.
According to independent study conducted by Transportation Security Administration (TSA) concluded that no visible damage from normal scanning procedure under average traveling condition. But TSA warned that x-ray machines that scan “checked baggage” cause damaging streaks on most films and higher speed films show more damages.
How about the new Backscatter X-Ray machine?
Backscatter X-Ray machine emits far less radiation compared to regular airport x-ray scanners.
Still worry about x-ray damage?
TSA’s tips and precautions traveling with film products:
- You should remove all film from your checked baggage and place it in your carry-on baggage. The X-ray machine that screens your carry-on baggage at the passenger security checkpoint will not affect undeveloped film under ASA/ISO 800.
- Request a hand-inspection for your film if it has already passed through the carry-on baggage X-ray screening equipment more than five times.
- To expedite the security process of a hand inspection, you should consider carrying your film in clear canisters, or taking the film out of solid colored canisters and putting it into clear plastic bags.
- Consider having your exposed film processed locally before passing through airport security on your return trip.
- Do not place your film in lead-lined bags since the lead bag will have to be hand-inspected.
