Can a SLR camera pass the security check?

SLR camera security is not harmful, can you pass the security inspection machine?

Jin Ri'an Technology recommends that the security check of the subway or airport should be avoided as much as possible. Because the radiation of the X-ray security instrument is very small, the impact on the scanned object itself can be neglected. But there is a special kind of film - film, which is sensitive to X-ray radiation. According to an experiment conducted by the American Association of Photographic Manufacturers (NAPM) on different sensitivity films of different manufacturers in 1994, the ISO1600 sensitivity film did not find any imaging anomalies after 16 X-ray baggage scans. A slight imaging abnormality was found after the second scan. Kodak Company gave the recommendation that "the film of ISO400 and above should not be X-rayed."

A passionate photography enthusiast, in order to practice photography technology, and to capture the beautiful moments to share with you, every day when going to the company to work, carrying a Canon camera bag. In this case, every day you have to go through the subway, you have to undergo security checks, so you have doubts about whether the camera will be harmful to the camera after security check? ......

Later, after a series of search for answers, professional-level technical support was known:

The "X-ray" triggers the photosensitive component to generate a reverse current loop, which causes the semiconductor magnetic memory to be energized to wash away the original photo, which in turn causes the digital camera integrated circuit to short-circuit and burn the electronic components.

Any ray can change the molecular structure and crystal structure, and it can destroy DNA and cause cancer in humans. For semiconductor components, gamma rays can bombard holes in the PN junction to form impurities, thereby causing the pixel to become a dead pixel, and X-rays have the same effect, but the probability is small. Even with a metal box, the X-ray machine automatically increases the dose until it sees what is inside. Robot cameras working in the radiation area in nuclear power plants always have many dead pixels, because they are radiated.

If you take the subway or plane for security inspection every day or every three or five times, it will be difficult to say that there is no bad point in the SLR camera in one year. However, it's just that you didn't care what caused it.

In other words, when the security check is actually taken, your camera has already suffered a lot of gamma rays or X-rays. Maybe you have no problem for dozens of times. I really don’t know that it really collapsed one day. Need to pay attention!

Therefore, if your camera has undergone a few security checks, try to avoid security checks later.
