Now, for the sake of safety, we have to go through the security check when we take cars, trains and high-speed trains, but flying is stricter to prevent people from carrying dangerous goods and causing harm to people. So what images will the staff see on the screen when the airport passes the security check? In fact, this is the principle of X-ray perspective, which makes X-rays appear imaging reaction on the computer after computer calculation and analysis. Moreover, different substances have different optical reactions when imaging, so it will be judged whether people have harmful substances.

Security inspection should start with the 9 1 1 incident in the United States. At that time, the American government stipulated that every passenger entering the airport should be searched, which made many female friends feel embarrassed and uncomfortable, and also led to particularly low efficiency. Therefore, the X-ray method is used to check and the image is formed by calculation on the computer, which will avoid the embarrassment and injury caused by the search. X-ray can display every part and organ of our body on the computer, including our luggage. Different substances will form different lights on the computer under the irradiation of X-ray, so it will be a good way to judge whether passengers carry dangerous substances.

But many passengers will worry about whether the radiation brought by X-rays will endanger our health. In fact, you can rest assured that the X-ray radiation is very small, even negligible, so there is no need to panic and worry. It won't harm our health during the security check. However, so far, the biggest controversy we have received is our privacy. In fact, there is no need to worry about this problem. With such a large passenger flow, the security inspector doesn't know who you are. Its main observation is whether you have.

Therefore, I hope that for the safety of ourselves and others, we will cooperate with the security inspectors to carry out routine inspections, instead of not cooperating with inspections for reasons such as harming our health and privacy, which will bring huge workload to our security inspectors and waste the time of passengers behind.
