With the development of China's rail transit construction, more and more people choose to take the subway to travel easily. "People have passed the security check and the security check machine will become the norm." However, if fresh food such as fruit and steamed bread passes through the security inspection machine, will there be radiation residue? Is it safe to eat these X-ray-irradiated foods? Hefei Railway Company responded to the above questions.

A related person from Hefei Railway Company said: You don't have to worry about the radiation from the security machine. Because the radiation of an object mainly depends on its own content and composition, foods such as fruits will not be left behind due to X-ray irradiation, let alone accumulated damage. “The freshly packaged food on the market needs to pass radiation, such as gamma rays, for radiation sterilization, which is good for food preservation without any residue,” he said.

After the food is irradiated, is it radioactive or toxic, and is the nutritional value damaged? In this regard, the source revealed that the international food radiation safety demonstration and testing began as early as the 1960s. After long-term animal testing and human testing, it has been proved that irradiated foods are not available to humans. Harm, "Foods that are preserved by irradiation, foods that are irradiated with a prescribed dose are safe, and the treated foods are free of radioactive materials and are not carcinogenic, teratogenic or mutagenic after consumption."
