How does people screening work?

People screenings are available with optional radiation detection capabilities in a single integrated system. The radiation detection performance must meet the requirements of applicable standards for people screening. With the radiation detection option, people are automatically inspected for both metallic and radioactive materials as they walk through the people screening. The user-friendly inspection operation of people screening is the same as for metal detection alone.

How does people screening work?

People screening works by using the principle of electromagnetism. It is in general known that any kind of electricity would generate a magnetic field around it. When this electric field passes over a metal object of any kind, the field passes right through it. The electrons in it are induced to move and produce a magnetic field of their own. In addition to this, it also creates a secondary magnetic field as well. This secondary magnetic field this created is what is detected by the people screening. The first coil induces the magnetic field into the metal object that a person might be carrying, whiles another coil in the people screening picks up this potential secondary magnetic field and accordingly sets off an alarm.

All people screenings work on the same principle, albeit in different ways. A hand-held detector is one of the most common ones even today. But in places where there is a high amount of people traffic, people screenings are used.

The only difference in the case of a people screening, in comparison to traditional ones, is the way in which the technology is used. People screening uses what is called Pulse Induction or PI technology. The PI system works by sending powerful and short bursts of current through coils of wire. Each of these pulses generates a short magnetic field in the coils of wire.

People screenings have these coils placed all around the individual, meaning that metal located in any part of the body can be easily detected by security personnel. In addition, people screening also allows the personnel to know the exact place where the metal object is detected.

What is the difference between walk-through mobile phone people screening and traditional people screening?

Everyone knows a little about people screening. The security gates we pass through by subway or high-speed rail are all people screening. People screening will not only alarm when metal objects are detected, but also alarm items carried by the human body, which will cause misjudgment and delay time. The walk-through mobile phone people screening mainly detects mobile phones and electronic products with transmission functions. People screening does not alarm the human body's carry-on items such as necklaces and watches.

Traditional people screening will alarm, as long as there are metal objects on the passers' bodies, mainly for metal alarms. Ordinary people screening mainly uses magneto-electric compatible dual detection source technology, which can generate alarm when the human body carries metal objects. This type of people screening can accurately detect the metal objects carried on the human body or in the body of the hand or the objects containing metal.

The walk-through mobile phone people screening is mainly used to detect whether the passer-by is carrying a mobile phone. If the passer-by carries electronic products such as mobile phones, notebooks, Pads, mobile hard drives, the people screening will alarm. At the same time, this type of people screening cannot alarm the metal objects carried by the human body, which only alarms for mobile phones and electronic products with the transmission function.

Why we need people screening?

The issue of security has become a paramount concern in today’s world. Given the range of threats that are faced by society in these times, it is only a given that a range of security measures have been taken up by society, in one form or another.

Of the many such measures that have been taken, one of them most iconic would be that of people screening. People screenings are the security devices that have become an important feature wherever there is a possibility of a security threat. You can find people screenings today in places such as important public buildings, airports, seaports, railway stations, private establishments and even schools. People have started to deploy people screening in a wide range of places, where we are deemed to be useful.

The people screening has been around for quite some time, and has been used largely for security and safety purposes. Since knives and guns are traditionally made from metal such as steel, people screenings are seen as a very effective way to find them.  The military used people screening for a similar purpose to detect landmines.  Additionally, hobbyists and historians found another use for people screening to the detect buried treasure and antiques.

In short, people screening has proven itself to be immensely useful to people from all walks of life.
