Investigation will be safe at Delhi airport, trial of less harmful scanner started

Delhi IGI Airport New Full Body Scanner : The pre-flying test at Delhi’s Indira Gandhi International Airport (Delhi International Airport Ltd -DIAL) will now be safer and less harmful to the body. For this, IGI has started the trial of Automated Full-Body Scanners. This machine, made by American Defense Aviation and Information Technology Company Leidos, is installed in the security check part of Terminal 2 of the airport.

How long will the trial of full body scanner last?

DIAL, a GMR-led consortium that runs the airport, will install the full body scanner at the airport as per the instructions of the Bureau of Civil Aviation Security (BCAS). According to Videh Kumar Jaipuriar, CEO of DIAL, this trial will last for 45-60 days. After the evaluation of the results, on the successful completion of the trial, these scanners will be installed at the airport under the guidelines of BCAS.

Kovid-19 and scanner prices put the brakes

It is worth noting that in the year 2019 itself, BCAS had asked to install these scanners at 84 airports across the country within a year, but due to Kovid-19 Pandemic, this work has been very difficult. There was a major hurdle. Because of this, most of the airports missed this deadline to install these scanners. Along with this, the cost of this scanner was also an issue. The cost of this scanner installed in the security check part of Terminal-2 of IGI Airport is four to six thousand crore rupees. Whereas the price of Door Frame Metal Detectors installed at the airport is around 50 to 80 thousand rupees.

How does this scanner work?

Full-body scanners use millimeter wave technology to detect both metallic and non-metallic objects. Millimeter waves are electromagnetic waves at the upper end of the microwave band, which range from 30–300 °C. Extremely High Frequency (EHF) of gigahertz (GHz) are in the EHF range.

These millimeter waves easily pass through the material of ordinary clothing. Because of this, any hidden object can be easily seen through them. In this, an imaging system uses the reflected wavefront to produce a three-dimensional picture on the monitor, which easily shows the shape and size of the hidden object.

According to DIAL, these scanners will be able to detect non-metallic items such as narcotics, prohibited or illegal items made of plastic explosives and rubber-like substances that cannot be detected by metal detectors. Along with this, the scanner will also detect the size-shape and location of the hidden objects in the internal parts of the body.

convenient for air travelers

According to DIAL officials, the passenger will have to enter the glass-framed machine and raise his arms. Two antennas in Millimeter Wave Scanners usually transmit the waves simultaneously as the frame of the machine rotates around the passenger. Screen monitoring officers will be able to easily see any illegal object detected by the scan. If no danger is detected, the passenger will be diverted beyond the security hold area.

Officials have said that this machine can scan the body and give results on the screen in less than six seconds. This machine has the capacity to test about 200-300 people per hour. During the current checks at the airport, passengers are required to remove their jewelry, shoes, belts, phones, equipment and any other items that may trigger the metal detector.

In testing the new millimeter wave scanner, passengers can go to the machine to check without taking anything out. According to an official – once the passengers are fitted with the machine, there will be no need for any physical search or undressing. This scanner will speed up the security check. Now metal detectors will be used only for special category of passengers such as wheelchair-bound persons, senior citizens or people who do not pass the scanner. Officials said that the responses of passengers, security personnel, DIAL and BCAS are being recorded during the trial.

Good for the health of passengers

Officials said the new body scanner will be a safer option for passengers as it does not use X-rays or ionizing radiation. BCAS has recognized that millimeter-wave technology should be used to avoid harmful X-ray radiation. According to Leidos, the machine’s signal is 1,000 times less powerful than that of a cell phone wireless handset.

It is approved by the Transportation Security Administration (TSA). It has been installed at all airports in the United States. However, officials have urged the US company to address concerns about possible violations of the privacy of passengers. To this the company has said that it is a contactless process that does not photograph the person but only highlights the “dangers” of a generic mannequin figure on its screen.

On the other hand, in the case of X-ray machines, there were reports that a “clear picture” of the body was being created in it, bypassing the privacy concerns of the passengers. Jaipuriar, CEO, DIAL said, “Safety and safety in civil aviation is a major concern for all. As an airport operator, DIAL is continuously working to make the process smooth for the passengers without compromising on it. CISF is doing a tremendous job. Now, we have installed an advanced Full-Body Scanners at the airport. It takes care of the privacy of the passengers during the security check and there is hardly any ill effect on their health.
