The basic principle behind Security X-Ray Scanners is to detect hidden threats using X-rays. The technology has been used in both medicine and security. Security X-Rays are printed in colour, which allows the security personnel to identify various objects. They are cost-effective and compact. Different models are available to suit varying business requirements. Here is a quick rundown of the main features of these machines.
The X-ray images from an X-ray system are processed using a software program provided by the manufacturer. Each manufacturer has their own software, and the ease of use varies between models. The images are normally magnified by four times. The images are recorded for Test 1 and materials discrimination. Depending on the model, you can use the software to determine whether an X-Ray system is sensitive to certain materials.
Security X-Ray Scanners are used in airports, railway and bus stations, government offices, embassies, and hotels. These machines provide low-dose radiation and can detect a wide variety of dangerous metal, organic, and inorganic substances. The radiation produced by these scanners is similar to the amount of natural radiation, which is absorbed by humans. These machines are also helpful in the detection of narcotics and explosives.
In one embodiment, an X-ray system comprises a large tunnel that is sufficiently large to scan a standard shipping container. This tunnel may have several independently movable test modules such as a materials discrimination module, a resolution module, and a penetration module. Each module may comprise a plurality of rotatable elements that may be metal plates, wedges, or other materials. Each element may present a number of different thicknesses to X-rays passing through it.
