OnePlus, Google Pixel, Motorola and other smartphones emit highest SAR radiation in India: report


Almost every electronic device around us emits radio frequency radiation, including our smartphones. These consumer devices accompany us most of the day, whether we are traveling, at home or even sleeping. However, all levels of radiation are tested and are generally below the electromagnetic spectrum defined by countries. Although these do not harm us in any way, some smartphones emit more radiation than others – which of course is not good news. These radio frequency radiations, if amplified, can increase the heat levels of the part of the body next to which they are placed. However, even this is not enough to raise core body temperature or alter DNA in any way. Nevertheless, it is best to stay away from handsets as much as possible so as not to be affected in the long run.

Now comes the obvious question – Which are these smartphones that emit more radiation than the others?

Smartphones with the highest radiation levels

Diving deeper into the matter, Bankless Times mentioned a list of smartphones that emit the highest radio frequency (RF) radiation as of today, based on data from the German Federal Radiation Office. According to the report, Motorola and OnePlus are two of the biggest issuers. The list also includes smartphones from Google, ZTE, Sony and Oppo. The rankings are based on the SAR value (Specific Absorption Ratios) which measures the rate at which the human body absorbs radio frequency electromagnetic field (RF-EMF) waves. It is measured in watts per kilogram (W/Kg). Here is the list :

– Motorola Edge: 1.79 W/Kg

– ZTE Axone 11 5G: 1.59 W/Kg

– OnePlus 6T: 1.55W/Kg

– Sony Xperia XA2 Plus: 1.41 W/Kg

– Google Pixel 3XL: 1.39 W/Kg

– Google Pixel 4a: 1.37 W/Kg

– Oppo Reno 5 5G: 1.37 W/Kg

– Sony Xperia XZ1 Compact: 1.36 W/Kg

– Google Pixel 3: 1.33 W/Kg

– OnePlus 6: 1.33 W/Kg

Indian SAR Limit by DoT and Safety Guidelines

In the list, almost all the mentioned smartphones are present in the Indian market, except for the first two – Motorola Edge and ZTE Axon 11 5G. In case you were wondering, the Department of Telecom (DoT) in India has set a SAR limit of 1.6 W/Kg for any smartphone in the country. Obviously, Motorola Edge is above the Indian SAR value and ZTE is right on the edge. This makes OnePlus 6T, the smartphone that arrived in India in 2018, one with the highest radio frequency radiation in India.

Radiation levels in a smartphone can vary for several reasons. The radiation volume can change depending on the type and model of the device, its age, the power of the transmitting antenna and the distance from the nearest cell tower.

However, if you still want to put the handset as far away as possible, the DoT has issued guidelines on this. You can hold the handset as far away from your body as possible, during calls you can use the headset (wired or Bluetooth) instead of placing the smartphone on your ear, do not lean your head against the phone (usually when lying down) as RF energy is inversely proportional to the square of the distance from the source, use the phone where reception is good as the device tends to increase transmission where signals are weak.
