Similarly one may ask, why are X-rays at airport checked luggage?
Some security devices use ionizing radiation to scan luggage. Safety measures are in place to make sure it does not expose workers and travelers to high-levels of ionizing radiation. Some devices, such as metal detectors, use non-ionizing radiation to scan travelers and make sure there are not carrying hidden items.
Likewise, why is the body X rayed in the bag? The bag, through which x-rays can easily pass, will remain closed while the body is scanned, both to respect the privacy of the dead and so as not to disturb any nonforensic personnel in the room. The Swiss emphasis on orderliness and precision extends to the task of death investigation.
Also, what do Airport X-rays see in your bag?
Backscatter X-rays are designed to show hidden objects beneath clothing or luggage. They can detect both metallic and non-metallic objects, ranging from guns to foods and plastics.
Do checked bags get X rayed at the airport?
