How Safe is film Airport X-ray Scanners

1. Check what National Association of Photographic Manufacturers in the USA says
2. Check what Kodak says
3. Check what The International Imaging Industry Association says
4. See X-ray Fog Appearance photos

pls dont confuse carry on baggage machine(normal conventional x-ray machine) with checked baggage machine used in US(Explosive detection systems).Still most of the airports use conventional machines.

Radiation Levels

Typical exposure levels that can be experienced with Different types of X-ray systems and some naturally occurring sources

Medical CT (CAT Scan):Up to 1,000,000 microRem

Chest Mammography:Up to 10,000 microRem

Background Radiation Denver (5000 ft): Up to 600 microRem per day

Miami (sea level): Up to 300 microRem per day

Inside vs. outside a building: Up to 25 microRem per day

Airline Passenger Dose One hour flight: Up to 500 microRem per hour

Rapiscan Secure 1000:Less than 10 microRem per exam

Explosive Sniffing Dogs

Explosive-Sniffing Dogs normally can work for up to two hours at a time, then they must take breaks of 20 minutes. Their sensing ability decreases in repetitive duty such as routine bag inspection, their preferred use is for checking an airplane or terminal in the event of a bomb threat, or as a second-tier inspection device for a bag flagged as needing further scrutiny.

Explosive Trace Detection(ETD) Machines

These machines can) Machines detect minute traces (e.g., a millionth of a gram) of explosive residue picked up on a swab. The swab is inserted into the machine, which heats it and samples the vapors for specific chemicals. Trace detection can be used on a random basis, at passenger screening checkpoints, to check the outside of selected carry-on bags for explosive residues. Closed Bag trace detection can be used in combination with EDS machines

Automated X-ray Machines

Automated X-ray systems are used for the first level of baggage screening. While not as accurate as EDS machines, they are much faster and much less costly. Typically, they operate at a rate of 1,200 to 1,800 bags/hour, faster than explosive detection systems (EDS). Bags flagged by the automated system as “questionable” are sent to operator station, where a human operator reviews the image on a screen. Those bags not cleared by this second look are routed to an EDS machine. Automated X-ray machine is not sufficient by itself. But it permits the slow and expensive EDS machines to be used only for exceptional bags.

EDS Machines

EDS (explosive detection system) refers to machines that use computerized tomography (CT) technology similar to that used for CT scans in hospitals. By taking hundreds of X-ray pictures of a suitcase from different angles, the device can create three dimensional views of what is inside, including some indication of the relative density of objects.A trained operator can then spot items likely to be explosives. EDS systems processing rate is a slow .
