3 Tips of X ray Baggage Scanner (Security Screening Machine) You Need To Know
1. What is baggage scanner?
Ray Baggage Scanner is a special x-ray device that allows you to study the
internal structure of an objects and the processes taking place in it without
the need of opening. Security X Ray Machines are widely used to inspect
passengers' baggage at airports, train stations and metro stations. Currently,
there are many types of baggage scanners (Introscope or x-ray television system
in Russian), but the use of x-rays is most popular because of the convenience
and comparative simplicity. In this case, the so-called x-ray diffraction
analysis is carried out - due to the diffraction scattering of radiation, a
projection of the internal structure of the object is created. So, how does an
x-ray security scanner work.
2. What is the principle of baggage scanner operation?
The principle of operation of a modern security screening system is quite simple. Baggage or other inspected object moves along the conveyor and having landed inside the x ray tunnel, is irradiated with an x-ray tube from a certain angle: from above, from below or from the side, based on the design features of the device. During working, a part of the radiation energy is lost from the thickness and material of the object. The residual energy is recorded by special detectors and converted into electrical signals, which are processed in the processor unit. The denser the baggage, the less radiation gets into the detectors. Ultimately, the x-ray scanner generates the projection of the object being searched. which reflects its internal structure. The greater the thickness of the object, the darker it is obtained in the finnal image.
At present, there are multi-view security x-ray inspection system that generate images of several projections simultaneously and show on the monitor view of the objects from different angles. This significantly improves the quality and effectiveness of the search.
According to atomic mass Zeff code NO.7.8.9, x ray baggage scanners also can accurately calculate the density of any individual baggage item. This allows the detection of liquid and solid explosives.
Security X-ray Inspection Equipment is safe for inspected objects, since the energy of the radiating x-ray tubes is small with ranges from 80 to 160KV. This is not enough to harm inanimate objects or food. As for the people next to them, baggage scanner's body reliably protects them from radiation. The only place where radiation can go outside is the enetrance and exit curtains. They are made of a special polymer with the addition of heavy metals, in particular lead, and they shield radiation quite well. But at the moment of passing through them luggage they open, and the proportion of radiation goes outside. Therefore, do not get inside to the tunnel of x-ray machine for quickly picking up your suitcase.
3. How to choose a baggage scanner?
First of all, when choosing a suitable model of security screening equipments, pay attention to the size of the inspection tunnel. To do this, you need to determine the size of the inspected items. Different tunnel size of machine is for inspecting different size of suitcase, baggage or cargo.
An important point is the way to load objects into x ray machine. Devices can be with bottom and top loading. If you need to inspect the heavy luggage, you should take a x-ray security inspection equipment with a lower load. For small things, a top-loading appliance is suitable.
When conducting mass events, it is necessary to prepare the baggage scanner for working, so that you can provide screening on demand. Such equipment should not be construed as the only effective way to ensure safety. At large public events, you can not do without other proven measures like security metal detectors, explosive detectors, liquid scanners, under vehicle inspection system, etc.
