Will the food go bad after passing through the x-ray baggage scanner?
Nowadays, many passengers will refuse the security check when taking the subway, and sometimes even conflict with the security personnel. One of the reasons is that many office workers now prepare their own lunch at home, and then take it to the company to eat. Cooking by themselves is not only delicious but also saves money, so everyone is afraid that the food will deteriorate during the security check. In reality, many people reject security inspections. One of the reasons why everyone rejects them is that they don’t understand the principles of the
x-ray baggage scanner. Today, Fuanshi security system will tell you whether the food will go bad when it is scanned by the
x-ray baggage scanner, and let’s get to know the most commonly security inspection equipment—the x-ray baggage scanner.
The x-ray baggage scanner, also called X-ray machine or baggage screening machine. Everyone is familiar with it. It is the main baggage screening device for subways and airports. The principle is very simple, it is to use the ability of X-rays to penetrate matter to detect objects. Depending on the density, thickness, and composition, the penetration ability of x-rays is also different. The x-ray baggage scanners are used to identify objects in luggage based on their ability to penetrate various substances.
The x-ray baggage scanner can not only recognize the shape of the object, but also display the color. The colors of various substances are different. Organic materials such as paper, clothes, and various foods usually appear orange. Mixed materials and light metals, such as those containing sodium, silicon, and aluminum, are usually displayed in green. Iron, copper, silver, etc. are displayed in black and blue. The brightness of the above various colors depends on the density and thickness of the material.
Many people worry that the food in their bags will go bad after passing through the x-ray baggage scanner. In fact, it is no need to worry too much about this. The X-rays emitted by the x-ray baggage scanner have very low power and the baggage will be only tested once. The radiation dose received is less than 5 microsieverts, which is much lower than those used for food irradiated for sterilization and preservation.
Many of the foods we eat are actually irradiated. This is also the case in other countries. For example, the US Food and Drug Administration and the US Department of Agriculture have approved the following foods to be irradiated for sterilization and preservation, such as packaged frozen meat and poultry, Fresh fruits and vegetables, and grains, etc.
At present, there have been many accidents involving plane crashes and subway bombings in the world, all of which are the consequences of terrorists bringing dangerous goods onto transportation. Therefore, the more careful the security personnel is, the safer the passengers will be! We should have a positive attitude to face the check of security personnel, not only for ourselves, but for everyone!
