The metal security screening gate at the airport

The Ministry of Land, Territory and Transport of Japan, in order to prevent aircraft terrorist attacks caused by explosives and murder weapons that cannot be detected by metal detectors, plans to introduce “whole scanners” for security screening using electromagnetic wave-perceived clothing at airports throughout the country with international routes by 2020. It is expected that the tests will be launched at three airports, namely, Sungda, Haneda and Kansai, during the year. The installation of such a full-body scanner has been promoted at the Euro-American airport, but Japan has been slow to import, considering the cost of one tens of millions of yen and privacy issues. Japan currently uses metal detectors and randomly extracted passengers for contact security.

Metal detection function

The metal detection security screening gate must have a high-security requirement, which includes the following factors:

I’m sorry. (b) The consistency of the magnetic field, which is the key to detection;

3. Metal detection security screening gates must be sufficiently capable of detecting persons, regardless of the speed at which they pass;

This post is part of our special coverage Syria Protests 2011. There is also a need for the capability to detect iron and non-ferrous metals.

The detection area for the metal security gate.

Twelve overlapping mesh detection areas based on the basic structure of the body. Interactive launch and reception, and precise location of metal articles. Weak and blind areas in detection areas are eliminated with greater sensitivity and more stable performance. Infrared scanning of both sides, rapid capture of sensor signals, elimination of detection errors caused by delayed sensory passage in the human body, and automatic counting of the number of passing persons. The 12 main detection areas have a 1000-degree sensitivity procedure, which pre-empts the possible location and volume, weight and size of the metal articles, depending on their actual use.

Besides, is there any electrical radiation at the security gate?

Any electronic product has some electromagnetic radiation. There is also a lot of electromagnetic radiation around us. Radio, television, cell towers, high-pressure lines, computers, television, microwaves, electromagnetic furnaces, mobile phones, etc. It is not difficult to see from the above table that, like other electronic devices, the security gate produces radiation when used, but the electromagnetic radiation of the security gate is minimal compared to those electronics.

In conclusion, it should be clear whether the metal security screening gate is harmful to pregnant women.
