According to the relevant personage of China Radiation Protection Association, the radiation problem of security X-ray machine is divided into two aspects. One is a high-radiation X-ray machine for baggage security inspection at the station. This kind of equipment is a multifunctional detection source, which needs to penetrate thick steel plate when working, so its radiation source has a large workload and will produce certain X-ray radiation. However, because the baggage security machines are all radiation-proof, you can't put your hand into the X-ray machine during the inspection in Lian. The other is what we usually call a medical X-ray machine. Because the energy used by this machine is very low, usually between 50 and 250 milliamps, it will not produce any radiation to the human body. In other words, even if the doctor puts his hand into the machine, it won't be hurt. Therefore, it is necessary to distinguish between different situations to find out whether the security X-ray machine has radiation on the human body.
Although direct X-ray irradiation will have an impact on the human body, X-rays will not be stored on objects, so the water and food detected by X-rays have no impact and can be safely eaten.
The radiation of an object mainly depends on its own content and composition, and foods such as fruits will not remain due to X-ray irradiation, and will not accumulate damage. International demonstrations and experiments on food irradiation safety began as early as the 1960s. Long-term animal experiments and human experiments have proved that irradiated food is harmless to human body.
