Why do you need to wear vest take an x ray but not at the checking point air port?

During an X-ray examination:

- Radiation protection: The vest, commonly referred to as a lead apron or radiation protection garment, is designed to shield sensitive body parts, particularly the reproductive organs and the thyroid, from unnecessary exposure to ionizing radiation during an X-ray procedure. Lead, a dense material, effectively absorbs X-rays, significantly reducing the amount of radiation reaching the shielded areas.

- Minimizing unnecessary radiation exposure: X-rays involve the use of ionizing radiation, which can have harmful effects on human tissues if not properly controlled. By wearing a lead apron, the patient's exposure is limited to the specific area being examined, reducing the risk of potential harm to other parts of the body.

At airport security checkpoints:

- Low-energy radiation: The security screening devices used at airport checkpoints employ low-energy X-rays or backscatter technology to detect potential threats. These devices emit significantly lower levels of radiation compared to medical X-ray examinations, posing a minimal risk to individuals passing through the checkpoints.

- Brief exposure: The exposure to X-rays at airport checkpoints is typically brief, lasting only a few seconds as individuals walk through the security scanners. This short exposure duration further reduces the potential health risks associated with airport X-ray screening.
