How does the airport xray machine work?

Answer 1

The airport x-ray machine works the same way as what a hospital or a doctors office would use. X-rays pass through objects that are less dense and stop at those objects that are dense, and the dense objects will show up as white on the screen.

Answer 2

No and yes, airport xray machines can see shin bones, knee implants but cannot see ribs or inside body cavities.
No&they're less harmful than Medical CT Scans.

Backscatter X-ray is an advanced X-ray imaging technology.Traditional X-ray machines detect hard&soft materials by the variation in transmission through the target.In contrast,Backscatter X-ray detects the radiation that reflects from the target.It has potential applications where less-destructive examination[airport security machines]is required&can be used if only one side of the target is available for examination.

The technology is one of two types of whole body imaging technologies being used to perform full-body scans of airline passengers to detect hidden weapons,tools,liquids,narcotics,currency&other contraband.A competing technology is millimeter wave scanner.These airport security machines are also referred to as "body scanner", "whole body imager (WBI)", and "security scanner".
