totally different. The security door is a magnetic field, and the security machine is an x-ray.
Security gates now use electromagnetic fields to detect metal objects. Any electronic product has a certain amount of electromagnetic radiation, but compared to other types of electronic products, the electromagnetic radiation of metal detection security doors is minimal. The metal detection security door is the principle of electromagnetic coupling, weak magnetic field induction technology, the power is very small, many times smaller than the power of the mobile phone during the call, and the radiation is also smaller than that of the computer monitor, and its radiator frequency is safe for the human body.
According to China's "Basic Standards for Ionizing Radiation Protection and Radiation Source Safety", the radiation dose to the public must not exceed a specified quantity in one year. The conversion calculation according to the prescribed value of this dose is equivalent to the amount of radiation a person has been standing for a long period of 52 days at 10 cm in the entrance and exit of the security inspection channel.
Unlike security gates, security inspection machines (machines that check luggage) are X-ray settings, but their inspections are all in hidden lead curtains, and even the staff next to them will not be affected. Therefore, I would like to remind you that when bags and other items pass through the security screening machine, you must wait for the bag to come out before taking the bag, and you must not rush to open the curtain to take things to avoid being exposed to X-ray radiation.
