In modern food safety management, X-ray food inspection technology has become an indispensable tool. As consumers pay more and more attention to food safety, manufacturers and regulators are also working hard to improve food safety. X-ray food inspection technology, which uses high-energy X-rays to penetrate food and detect possible foreign matter (such as metal, glass, stone, plastic, etc.), has been widely used in food production lines. However, many people may have doubts about the safety of X-ray food inspection, worrying that the radiation of X-rays will affect the food itself or the health of workers. This article will explore the safety of X-ray food inspection from different angles, explain its working principle, and eliminate related safety concerns.

1. Working principle of X-ray food inspection technology

X-rays are high-frequency electromagnetic radiation that can penetrate objects and show the internal structure of objects. In food inspection, X-ray equipment uses its penetrating power to form an image by scanning foreign matter in food. When X-rays penetrate food, foreign matter (such as metal, plastic, glass, etc.) will absorb more X-rays due to their high density, causing these areas on the image to darken and be detected. This technology can effectively identify foreign matter in food packaging and ensure the safety of food.

Modern X-ray food inspection equipment usually has high resolution and scanning speed and can detect tiny foreign matter quickly and accurately. This makes it applicable not only to the detection of traditional foreign matter such as metal and glass but also to some more difficult-to-detect foreign matter such as plastic, rubber, sawdust, etc.

2. Radiation safety of X-ray food inspection

X-ray, as a radiation source, has a certain degree of radioactivity, which has also caused many people to worry about its safety. However, the radiation dose of modern X-ray equipment has been greatly reduced, far below the level that is harmful to the human body. In order to ensure the safety of X-ray food inspection, the following points are crucial:

Low-dose radiation: The radiation dose used by X-ray equipment in modern food inspection is very low. In fact, the radiation level of X-ray food inspection equipment is usually lower than the radiation dose of medical imaging (such as CT scans or X-ray examinations). According to the research and standards of the International Commission on Radiological Protection (ICRP), the amount of X-ray radiation in food inspection has been reduced to a level that is harmless to the human body.

Radiation restrictions and safety measures: X-ray equipment is usually equipped with strict radiation protection measures to ensure that operators and food are not exposed to unnecessary radiation. The equipment itself is usually designed with a shielding structure to prevent X-rays from leaking into the environment. In addition, the staff will also follow the radiation safety standards during operation to ensure safety during the operation.

Compliance with international safety standards: Most X-ray food inspection equipment is internationally certified and meets the radiation safety standards around the world. For example, the U.S. Food and Drug Administration (FDA) has strict regulations on the safety of radiation equipment, and the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO) have also provided detailed guidance and restrictions on the use of radioactive radiation.

3. Impact on food: Will radiation change the nature of food?

Another common question is whether X-ray food inspection will change the physical or chemical properties of food, especially whether it has an impact on the nutritional content of food. In fact, the impact of X-rays on food during the inspection process is minimal, mainly manifested in the following aspects:

Does not change the nutritional content of food: The role of X-rays is only to penetrate and scan the food to check the internal structure. The radiation energy in the process is very low and will not cause any changes to the chemical composition, nutritional content, or taste of the food. Scientific research shows that X-rays do not destroy vitamins, minerals, or other nutrients in food, nor will they cause food to deteriorate.

Does not affect the taste or texture of food: X-ray inspection is carried out in a non-contact manner. It does not directly react chemically with food, so it does not affect the taste, smell, or texture of food. After the food is inspected by X-rays, it remains intact and there is no change in quality.

Low-dose radiation does not cause radiation contamination of food: Radiation contamination usually refers to the exposure of food to high doses of radiation, which causes changes in its internal structure and produces harmful substances. During the X-ray food inspection process, the radiation dose used is far below the harmful level, and the food will not be "radiated" or contaminated. Therefore, it can be safely assumed that X-ray food inspection has no negative impact on the safety of food.

4. Safety safeguards for X-ray food inspection equipment

In addition to radiation safety, the design and operation procedures of X-ray food inspection equipment will also ensure the safety of staff and consumers. The main safeguards include:

Automated and intelligent design: Modern X-ray food inspection equipment is increasingly adopting automated and intelligent designs, which can minimize human intervention during the inspection process and ensure that the operator is not directly exposed to the radiation source. The equipment is usually equipped with shielding devices to prevent radiation leakage.

Worker protection: Operators usually receive professional radiation safety training, are familiar with the operating specifications of the equipment, and wear appropriate protective equipment, such as radiation-proof work clothes and gloves. In addition, workers keep a certain distance from the X-ray equipment to further reduce the risk of radiation exposure.

Regular inspection and maintenance: In order to ensure the long-term safety of the equipment, X-ray food inspection equipment needs to be inspected and maintained regularly. The radiation source, shielding device, etc. of the equipment will be inspected to ensure that they are in good working condition to avoid radiation leakage or other potential safety hazards.

In general, X-ray food inspection is a safe and effective technology that is widely used in food production lines to ensure the quality and safety of food. The radiation dose used by modern X-ray equipment is far below the harmful level, and it has been strictly designed and regulated for safety to ensure that it will not cause any harm to the food itself, the staff, or the consumer. As the technology continues to develop, X-ray food inspection will continue to play an important role in food safety and bring more protection to the global food industry.
