A security X-ray machine is a common security screening device used to identify and discern items in luggage or luggage. Here are some tips for identifying items:
1.Pay attention to color and shape: Observe the color and shape of the item on the X-ray screen, different materials and items have different densities and characteristics, which can help identify suspicious objects.
2.Combine edges and contours: Pay attention to the edges and contours of the object, observe the shape and edges of the object on the X-ray screen, and pay attention to whether it is different from common items.
3.Be aware of density differences: Items made of different materials may show different density differences on the X-ray screen. Density differences in metals, liquids, plastics, etc., can provide clues.
4.Distinguish by cascading: If an item is obscured by other items, care can be taken to distinguish different layers and positions to determine the characteristics of each item.
5.Rely on expertise: Security personnel often receive specialized training and instruction to identify suspicious items. They have a lot of experience and expertise to identify items more accurately. If in doubt, you can consult a security professional.
It is important to note that the X-ray machine is only an auxiliary tool, and for some special items or items that are highly concealed, it may be necessary to refer to other security screening measures, such as manual inspection or the use of other advanced security screening equipment. Maintaining compliance with security regulations and cooperating with the instructions of security personnel is an important principle to ensure a safe and smooth passage.
