What can you see on the security screen?

In daily life, we will go to some public places, or crowded places, and we may have to go through security checks, especially when flying or taking the high-speed train. Because security inspection is very important for detecting some prohibited items carried by human body, everyone may put away some prohibited items in their lives, but this situation may still exist due to negligence, so in order to avoid some dangers and losses on the plane, these things with abnormal sounds will be screened out through security inspection. You can see a lot of things on the human body through the security inspection instrument, because the security inspection adopts X-ray scanning imaging technology, and it is an electronic device for security inspection of luggage and people, which can judge the safety of items and has little harm to the human body. On the security screen, you can completely see the bones of a person's body and the items in each suitcase. Even if your suitcase is not opened, you can clearly see what is inside when you pass the security check. The image you see on the security screen is very similar to that taken by the hospital. The film of the hospital is only a partial picture, but the picture displayed by the security check is the outline of the body. The security check image can fully show the characteristics of a person's bones, even the contrast of various densities in your body. In fact, some private things can't be seen on the security screen, and there will be no accidents in ordinary daily necessities. You can see some disabled people's artificial limbs and various metal objects on the security screen, so it is basically difficult to hide them during security inspection. The purpose of setting up security check is to prevent some lawless elements from bringing contraband into public places to harm others through this passage, so all you can see above are normal or prohibited items, which is also to ensure the safety of every passenger.
