Airplanes, photographic equipment through the security check, X-ray or other scanning equipment, will be illuminated bad equipment Please teacher guidance

The principle of the X-ray screening machine in the subway is the same as the X-ray film used in the radiology department of the hospital, but the radiation dose is much smaller. The main machine inside the ray, the package and luggage irradiation, if you carry electronic equipment to pass the security check, please be sure to pay attention to whether there is film inside, because the X-ray on the film has a certain effect, but on the digital product itself has no effect. If there is film inside the photographic equipment, you can take it out for manual security check.

Unexposed film by X-ray will be cumulative, even if the film sensitivity is only 100, do not let it more than 5 times the X-ray machine. x-ray on the film is still there, the difference is only the degree of depth, light particles coarsening, slightly off-color, heavy strange streaks or even produce a strong gray haze.

ISO 800 rolls over 3dx 6000 airport scanner 5 times, basically waste. Image from the web. Film with a sensitivity of ISO 400 or less, over one or two times is basically not a problem, but the ISO 400 or more rolls will hang, and the higher the sensitivity, the more affected.

Not only high sensitivity film, but also reversal film, movie film, try not to go through airport security. It's important to note that different security machines have different X-ray power, so if you're safe at this airport, it doesn't mean you'll be safe at another one.
