Many people are worried that there will be radiation during the security check, which will damage the human body. In fact, there are thick lead curtains on both sides of the x-ray security inspection machine. Two layers on each side, which is made of lead material, not to block dust. Mainly used to block x-rays, because lead materials are not penetrated by x-ray machines.

The x-ray recovered by the baggage inspection x-ray security inspection machine The power is very small, it is detected once, and the radiation dose received is less than 1μSv, which is far lower than those used for radiation sterilization of food. Many of the food we eat is actually irradiated, and x-rays do not stay in the food.
