X-ray checkpoint scanners use X-rays to create images of the contents of bags and other containers. They are commonly used at security checkpoints in airports, government buildings, and other locations to help detect prohibited or dangerous items that may be hidden inside bags or other containers.
While X-rays are a type of ionizing radiation, the levels of radiation emitted by X-ray checkpoint scanners are generally considered to be safe for human health. The radiation levels are well below the limits established by international safety standards, and the scanners are designed to minimize the amount of radiation exposure to both the operator and the person being screened.
In general, the risk of harm from a single X-ray checkpoint scan is very low. The amount of radiation exposure from a single scan is typically much less than the amount of radiation a person is exposed to from natural sources in their daily environment.
It is important to note that pregnant women, or women who may be pregnant, may wish to inform the security personnel at the checkpoint before undergoing an X-ray scan. While the risk of harm to a fetus from a single X-ray checkpoint scan is very low, pregnant women may wish to take extra precautions to minimize their radiation exposure.
