Abu Dhabi recently introduced a new method of Covid-19 testing in shopping malls, some residential areas and all land and air entry points.

The devices measure electromagnetic waves.

But what are they? And how do scanners detect Covid-19?

The National Explain.

These are waves created by vibrations between an electric field and a magnetic field.

All objects emit electromagnetic radiation, which is measured in waves, including people.

Most of the radiation emitted by the human body is infrared.

Ear and forehead thermometers check body temperature by detecting infrared radiation emitted by the human body, because hotter objects emit more heat radiation than colder ones.

Infrared cameras detect body temperature in the same way.

According to NASA, electromagnetic waves have peaks and valleys similar to those of ocean waves.

“The distance between the ridges is the wavelength. The shortest wavelengths are just fractions of the size of an atom, while the longest wavelengths scientists are currently studying may be larger than the diameter of our planet.

According to Abu Dhabi Media Office, the device uses an electromagnetic detector, which measures waves within a radius of five meters.

When a person enters the area, they alter the electromagnetic waves present.

The scanner measures these waves, “which change when the [ribonucleic acid RNA] particles of the virus are present in the person’s body, ”the media office said.

RNA generally acts as a messenger carrying DNA instructions.

A machine learning algorithm compares the information to the Covid-19 RNA molecule.

They may have Covid-19 and must present for a PCR test within 24 hours.

They will also be refused entry to places such as shopping malls.

Scanners are now used in shopping malls, some residential areas and all land and air entry points.

Very, according to a test involving 20,000 people, which showed “a high degree of effectiveness”.

The devices have been tested in Ghantoot, Yas Island and Mussaffah.

Jamal Al Kaabi, undersecretary at the Ministry of Health in Abu Dhabi, said the use of the scanners underscored the emirate’s commitment to protect public health.

“Abu Dhabi has adopted an integrated strategy to fight the Covid-19 pandemic, based on increased testing to ensure safe entry into the emirate, vaccination and the continued implementation of precautionary measures,” he said. -he declares.

Dr Al Kaabi added that the scanners would be used along with other screening methods such as PCR tests.

The system was developed by the Abu Dhabi EDE Research Institute.
