EMGblog.com: Today, it is no secret that smartphones in When they are active, they emit rays that must be below the virtual limit to obtain a license. The amount of radiation in different phones is different from each other, and therefore, knowing this amount accurately in each of the devices is very important. BanklessTimes website recently During a report, the amount of radio frequency emission from phones was investigated and a list of Android smartphones with the most radiation It has provided users with radio wave radiation. This report points to the lack of valid evidence for the damage of these rays, and the FCC has also spoken of a similar interpretation in this regard.

According to the findings of this report, which was published on Wednesday, April 6 of this year (April 17, 1401), Pixel phones Google and Xperia by Sony, among Android devices They are exposed to the highest level of radiation. However, there are examples with higher radiation levels in this list. In the BanklessTimes report Specific Absorption Rate or SAR (abbreviated Specific Absorption Rate) has been investigated in various smartphones. SAR measures the absorption of electromagnetic waves resulting from radio radiation (RF-EMF) by each kilogram of the human body, and its results are measured in units of watts per kilogram (W/Kg).

Smartphones with the highest amount of radiation

In the list published by BanklessTimes, the smartphone Motorola Edge has obtained the first rank in terms of the amount of emission of waves and its specific absorption rate is 1.79 W/kg. After this phone, Axon 11 5G product of ZTE with SAR equal to 1.59 and then Oneplus 6T are the next two most radiant phones on this list, with a specific absorption rate of 1.55W/kg. Sony also with two products Xperia XA2 Plus and Xperia XZ1 Compact, with SAR of 1.41 and 1.36 respectively watt/kg, the 10 devices with the highest wave radiation are ranked fourth and eighth.

The presence of Google phones among the 10 phones with the highest amount of radiation

Google also ranks high on the published list, and some products of the American tech giant, including Pixel 3 XL and Pixel 3a XL with SAR equivalent to 1.39 have occupied the fifth place. In addition, the Pixel 4a also has a specific absorption rate of 1.37 W/ kg, is among the ten devices with the highest amount of radiation. Besides these things, Pixel 3 is also similar to OnePlus 6 with SAR equal to 1.33 W/kg, ninth place and Oppo Reno5 5G also with a specific absorption rate similar to Pixel 4a next to this phone in the sixth place is placed

Of course, one of the people working in the Google Pixel team pointed out that the SAR data for all phones of this company, including Pixel 3 XL,Pixel 3 and Pixel 4a is published. According to him, “These phones are fully compliant with the regulatory guidelines in the countries where they are distributed. [plus] the latest Pixel 6 and Pixel 6 Pro have lower SAR values”.

The increase in the incidence of diseases such as cancer and efforts to control the factors that cause the occurrence of this disease have also placed the radiation of phones in the center of attention. As many countries have set levels for the acceptable amount of SAR that companies are required to comply with. For example, the US Federal Communications Commission (FCC) accepts a maximum of 1.6 W/kg as the allowable level of specific absorption rate and accordingly, Motorola Edge is the only device on this list whose SAR exceeds the limit set by the FCC. Of course, it should not be forgotten that all phones emit some level of radiation, and the amount of this radiation depends on several factors, including the type and model of the device, its age, the power of the transmitter antenna, and its distance from the nearest telecommunications tower.

Does phone radiation harm users?

In general, today’s phones emit radio waves in the electromagnetic spectrum. The emission level of these waves in 2G to 4G smartphones was in the range of 0.7 to 2.7 GHz, while the fifth generation devices emit these waves up to 80 GHz. Due to their low frequency, these waves have a low energy frequency and are non-ionizing. As a result, their little energy is not enough to change DNA and increase the risk of cancer. Non-ionized waves are electromagnetic waves in the range of 400 nm to 1 meter that are not able to ionize atoms.

Different types of electromagnetic waves in two types of non-ionizing and ionizing

Basically, mobile device users absorb energy from devices emitting radio radiation, and the only effect of this process seems to be heating the part of the body that is next to the mobile phone. Of course, this heat is so weak that it cannot significantly increase the temperature of the central part of the body. In addition, there is no evidence that RF radiation is harmful. However, the US Food and Drug Administration has suggested several measures to limit exposure to mobile device radiation, including using the phone for a shorter period of time or using hands-free and moving the smartphone away from the body, among them.

The data used in the BanklessTimes report was collected by the German Federal Office for Radiation Protection. However, some other sources have provided different data and, for example, in tests on the 2020 and 2021 models of the Motorola Edge phone, they have achieved figures of 0.81 and 1.00 W/kg, respectively; Figures that are much lower than the desired levels of the United States and the European Union.

Smartphones with the lowest amount of radiation

based on According to data from the German Federal Office for Radiation Protection, the list of Android phones with the lowest radiation starts with the ZTE Blade V10, with a specific absorption rate of 0.13 W/kg. After that, the ZTE Axon Elite with 0.17 W/kg and Three Samsung products namely Galaxy Note10+ 5G with 0.19W/kg, Galaxy Note10 with 0.21 W/kg and Galaxy A80 with 0.22 W/kg are in the second to fifth positions. In the rest of this list, the names of phones such as Galaxy A72 with 0.23 W kg and LG G7 ThinQ and Galaxy S20 FE Both are seen with a SAR of 0.24 W/kg. Galaxy M20 and Honor 7A also have the 9th and 10th positions in this list with specific absorption rates of 0.25 and 0.26 W/kg, respectively. . Of course, Motorola also thanks to the specific absorption rate of 0.27 W/kg Razr 5G has regained some of its credibility and ranked 13th among Android phones with the least amount of radiation. is dedicated.
