Each phone or smart phone to transmit part of the energy of the body and the rate of this process is determined by means of SAR. Which smartphones are for us theoretically the most secure, and that on the contrary?
According to Wikipedia , SAR (specific absorption rate of energy) ,, is a measure of the rate at which energy is absorbed by the body when it is exposed to radio frequency electromagnetic fields. It is defined as the power absorbed by the mass of tissue of the human body, and its unit is the watt kilogram (W / kg) ''. The maximum permissible consumer electronics market value in Europe is 2 W / kg (measured at 10 grams of tissue). In fact, there was no yet clear whether, how and how much radiation emanating from smartphones is bad for our health, but if someone attaches great importance to this, it interested him popular smartphones statement by the highest and lowest SAR.
Popular smartphones with the lowest SAR levels:
- Samsung Galaxy S7 Edge (0.264 W / kg)
- Asus ZenFone 3 (0.278 W / kg)
- Samsung Galaxy A5 in 2016 (0.290 W / kg)
- Lenovo Vehicles (0.304 W / kg)
- OnePlus 3 (0.394 W / kg)
- Galaxy S7 (0.406 W / kg)
- HTC 10 (0.417 W / kg)
- Sony Xperia XA (0.473 W / kg)
- Collect 5X (0.560 W / kg)
- Samsung Galaxy A3 2016 (0.621 W / kg).
According to the statement of ten popular smartphones with the lowest SAR, the Samsung does safest in terms of radiation smartphones. In the top there were as many as four models of the manufacturer of the Galaxy S7 Edge at the top.
Popular smartphones with the highest SAR levels:
- Collect 8 (1.5 W / kg)
- Huawei P9 (1.43 W / kg)
- Apple iPhone 7 (1.38 W / kg)
- Apple iPhone 7 Plus (1.24 W / kg)
- Collect 5 C (1.14 W / kg)
- Sony Compact Xperia X (1.08 W / kg)
- Sony Xperia XZ (0.870 W / kg)
- LG G5 (0.737 W / kg)
- Apple iPhone SE (0.720 W / kg)
- Sony Xperia X (0.720 W / kg).
This summary has been dominated by smartphones Apple (3 units), Sony (4 units) and Huawei, and at the top was Honor 8. Just this case is easily explained, because the smartphone offers active Dual SIM, so is equipped with up to two antennas and this inevitably increases the SAR. It does not change the fact that as many as 3 out of 10 smartphones list comes from Huawei.
Is there nothing to be afraid of?
As mentioned earlier, I do not have full agreement as to the dangers of radiation on the human body with regard to a certain height SAR. Besides, even Honor 8 is far from the norm approved in Europe. In my opinion, you need to approach the subject carefully and steer clear of smartphones with unusually high ratio of specific energy absorption rate, especially if it is dangerously close to the standards. You should also avoid situations such as the use of mobile phones while charging or holding it close to the head during sleep. In the end, forewarned is forearmed, do not you?
