Xiaomi Mi A1 at the top of the SAR ranking ... but it is not a place of honor

Before going into the article it is right to make a proper explanation to the Super Quark, albeit short. In very simple terms, the SAR (Specific Absorption Rate) indicates the energy absorption of phone radiation on our body within a certain period of time. Measurements of the SAR value are usually performed on the whole body or on tissue samples and tests are made during a call, ie the moment when the device emits more electromagnetic waves. In Europe the limit is 2 W / Kg in a sample of 10 grams of fabric. In the United States, the value must be less than or equal to 1,6 W / Kg. In the scientific field there is still much debate on the actual correlation between smartphone radiation and cancer cell growth, but in any case it is advisable to buy a smartphone with very low SAR values, premising that usually the most "dangerous" ones are those not really recent launch on the market.

Having said that, few people still consider the SAR value as an effective feature for the purchase of a smartphone, going beyond the simple technical and software specifications. Now I do not want to create any alarmism and underline the European limit of the SAR value equal to 2W / Kg. On this basis, every smartphone before it is available on the market is carefully checked by the German Federal Office for Radiation Protection, which after every check, also updates the list of all mobile devices under examination.


It is not up to me to say if smartphones are really dangerous or not, although the end user could in any fashion make a less excessive use, perhaps with some precautions that will only bring benefits in the long run. For example, you could start using earphones or hands-free where possible, but especially for some short communications you could send a message instead of making a call. In short, digital minimalism could begin to take more and more foot.

Very good ... it's good to know well about these things ... the user must become aware not only of the fact that a smartphone is cool or not

I would also like to read some details on 5G (without necessarily leading to surreal conspiracy theories). There is too little information, comfortable, and superficial to the "beauty of technology" 😉

If in doubt, I would lower the limit to 1.5 even in europe ...

I only say that the value of Sar calculated using the US method (slightly different) is 1.26 therefore absolutely in order even for US standards.

Nerd, Geek, Netizen, terms that do not belong to me. Simply myself, technology lover and provocative as Xiaomi does with his products. High quality at fair prices, a real provocation for the other most famous brands.
