The x-ray tube was removed to render the apparatus harmless before being put on public display, due to the possible risk of radiation burn or other health problems if it were switched on. The risk of radiation burns to extremities was known since Wilhelm Röntgen 's 1895 experiment, but this was a short-term effect with early warning from ...
Millimeter wave scanners should not be confused with backscatter X-ray scanners, a completely different technology used for similar purposes at airports. X-rays are ionizing radiation , more energetic than millimeter waves by more than five orders of magnitude , and raise concerns about possible mutagenic potential.
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible. To change this template's initial visibility, the |state= parameter may be used:
Full body scanner in millimeter wave scanners technique at Cologne Bonn Airport Image from an active millimeter wave body scanner. A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact.
An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
Rapiscan X-ray backscatter scanner Advanced Technology (AT) X-ray systems for baggage scanning. Rapiscan Systems is an American privately held company that specialises in walk-through metal detectors and X-ray machines for screening airport luggage and cargo. The company is owned by OSI Systems. [1]
The CTX (Computer Tomography X-ray) is an explosive detection device, a family of x-ray devices developed by InVision Technologies in 1990 that uses CAT scans and sophisticated image processing software to automatically screen checked baggage for explosives.
Backscatter X-ray is an advanced X-ray imaging technology. Traditional X-ray machines detect hard and soft materials by the variation in x-ray intensity transmitted through the target. In contrast, backscatter X-ray detects the radiation that reflects from the target. It has potential applications where less-destructive examination is required ...
