In our daily life, security X-ray machines have become an indispensable part of our lives. Whether it's at airports, train stations, public transport, or other places where security needs to be guaranteed, we can see security X-ray machines. However, many people may be confused about how to identify items through a security X-ray machine. Today, we're going to take a look at this topic and share some tips for identifying items.
First of all, we need to understand how the security X-ray machine works. Security X-ray machines use the permeability of X-rays to penetrate items and produce images. These images show the internal structure and shape of an item, which can help security personnel determine whether an item contains dangerous goods.
When it comes to identifying items, we can start with the following aspects:
Observe the shape and size of the item: By observing the shape and size of the item, we can make a preliminary judgment of what the item might be. For example, if an item is long or cylindrical, it may be metal or plastic;If the item is square or round, it could be a book or paper, etc.
Observe the color and density of the item: The density and color of different substances will also vary. For example, metal usually appears dark, while paper usually appears light. In addition, some high-density substances, such as diamonds, **, etc., will show a darker color under the X-ray machine.
Observe the internal structure of an item: By looking at the internal structure of an item, we can determine what an item might be. For example, if the inside of an item exhibits a honeycomb structure, it may be a foam product;If there is a clear hierarchy on the inside of the item, it could be a book or paper, etc.
Combine the above information to judge: By combining the above information, we can make a more accurate judgment on the item. For example, if an item is elongated, dark, and has a honeycomb internal structure, it may be one of the metal or plastic products.
It is important to note that although the security X-ray machine can help us identify items, it cannot completely replace manual inspection. Therefore, after identifying items through the security X-ray machine, it is also necessary to cooperate with manual inspection to ensure safety.
In conclusion, by mastering some knack for identifying items, we can better understand and use the security X-ray machine. At the same time, we need to be vigilant and follow the rules and procedures to ensure public safety and our own safety.
