Almost every electronic device around us emits radiofrequency radiation and that includes our smartphones as well. These consumer devices stick with us for the most part of the day, whether we are travelling, at home or even sleeping. However, all the radiation levels are tested and are usually under the electromagnetic spectrum set by countries. Although these don’t harm us in any way, some smartphones do emit more radiation as compared to others – which is of course not good news. These radiofrequency radiations, if amped up, can increase the heat levels of the body part it is placed next to. However, even that is not enough to raise the core temperature of the body or alter the DNA in any way. Nonetheless, it is better to stay away from handsets as much as possible so you don’t get affected in the long run.
Now comes the obvious question – Which are these smartphones that emit more radiation than others?
Smartphones With Highest Radiation Levels
Diving deeper into the issue, Bankless Times has mentioned a list of smartphones that emit the highest radiofrequency (RF) radiation at today’s date, based on the data from the German Federal Office for Radiation. As per the report, Motorola and OnePlus are two of the highest emitters. The list also includes smartphones coming from Google, ZTE, Sony and Oppo. The rankings are based on the SAR (Specific Absorption Ratios) value that measures the rate at which the human body absorbs radiofrequency electromagnetic field (RF-EMF) waves. It is measured in watts per kilogram (W/Kg). Here’s the list:
– Motorola Edge: 1.79 W/Kg
– ZTE Axon 11 5G: 1.59 W/Kg
– OnePlus 6T: 1.55 W/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 & Safety Guidelines
In the list, almost all the smartphones mentioned are present in the Indian market, except the top two – Motorola Edge and ZTE Axon 11 5G. In case you are wondering, the Department of Telecom (DoT) in India has set a SAR limit of 1.6W/Kg for any smartphone in the country. Clearly, Motorola Edge is above the Indian SAR value and ZTE is right on the edge. That makes the OnePlus 6T, the smartphone that came in India in 2018, one with the highest radiofrequency radiation in India.
The radiation levels in a smartphone can vary due to several reasons. The radiation volume can change based on the type of the device and model, its age, the strength of the transmitting antenna and the distance from the nearest cell tower.
However, if you still want to keep the handset as much away as possible, the DoT has issued some guidelines for it. You can hold the handset as much away from the body as possible, during calls you can use the headset (wired or Bluetooth) instead of placing the smartphone on your ear, don’t press your head against the phone (usually done when lying down) as the RF energy is inversely proportional to the square of the distance from the source, use the phone where reception is good since the device tends to increase transmission where signals are weak.
