X-ray technology has been in use for some years in the form of scanners designed to detect any suspicious packages. These scanners range from little ones in mail rooms to large, industrial sized ones commonly found in airports. The detection of weapons and other contraband materials is essential in maintaining the safety of people in the modern world.
While it goes without saying that X-ray scanners are found in the security section of airports, they are also located in a number of other places. The hand baggage zone at check-in and the cargo pallets also have X-ray scanners, working towards finding substances at various locations and lowering the risk of someone tampering with baggage.
