Answer 2

The professionals that most likely use X-ray technology are a dentist and an airport-security scanner.
A dentist would scan your teeth using X-ray technology to see whether there are any cavities within the teeth themselves which he couldn't otherwise see with the naked eye. An airport-security scanner would use this technology to scan your luggage to check whether there are any weapons and other illegal products.
