Will products such as mobile phone security screening gates and detection doors cause harm to the human body?

Almost all transportation hubs, exhibition halls, convention and exhibition centers, large-scale sports events and performance venues, important functional departments, prisons and some production, office and entertainment venues are equipped with security detectors and security gates at the entrance. It should be said that the most common place we walk is the subway station. The subway station also has a simple metal security gate, which is different from the mobile phone detection gate. Mobile phone detection gates are mainly used in confidential places and schools where they are now needed.

Then the difference between these two doors will be briefly explained by the editor.

Ordinary security gates will alarm as long as there are metal objects on the passers-by. The alarm is mainly for metals, so they are also called metal security gates.

The mobile phone detection door, as the name suggests, is mainly used to detect whether passers-by carry mobile phones. If the passers-by carry mobile phones, notebooks, Pads, mobile hard drives and other electronic products, the mobile phone detection door will alarm the walk-through security detector. At the same time, it can not alarm metal objects carried by the human body, but only alarm mobile phones and electronic products with transmission functions.

Since today I am mainly talking about radiation issues, I will simply tell you how to distinguish them.

The security screening gate can generate an alarm for passing metal objects because the door panels on both sides are equipped with detection sensors that can emit and receive changes in electromagnetic fields. When the person being inspected passes through the security gate, the detector will emit electromagnetic waves. The electromagnetic waves act on the metal objects they carry and cause the electromagnetic wave signal to change. The signal is received by the receiver and detected. The signal is then amplified and processed. When the signal volume reaches the set value, the alarm light in the corresponding height area will flash and sound an alarm. Electronic products containing metal, such as mobile phones, computers and other devices, will be detected whether they are turned off or on.

Compared with electronic products such as computers, televisions, microwave ovens, induction cookers, and mobile phones, the electromagnetic radiation from security gates is very small. The reason is that security gates use weak magnetic field induction technology and the power is very small. It is many times smaller than the power of a mobile phone during a call, and is also smaller than the radiation of a computer monitor. Therefore, electromagnetic radiation from security gates is safe.

Although the radiation from the hand security screening gate is relatively small and will not cause any harm to the human body, its function is not bad at all.

The mobile phone detection gate can filter out carry-on items such as metal buckles, metal belt buckles, keys, coins, wallets, cards, lighters, pens and other carry-on items without warning, including large umbrellas and water cups. The metal security screening gate is a security screening gate that detects metal. Since mobile phones also contain metal, metal security gates can also detect mobile phones. However, for scenarios where you only want to detect mobile phones, the false alarm rate of metal security screening gates is very high. Therefore, compared with mobile phone detection doors, mobile phone detection doors are obviously more practical in scenarios where mobile phone detection is required. It can detect whether passers-by are carrying mobile phones (it can detect whether they are turned on or off)
