Everyone, when it comes to going to buy a new smartphone , we tend to look at key features such as battery capacity, the possibilities offered by your camera, power and design, and even the manufacturer’s update policy. However, there is something much more important in what few are fixed: the SAR radiation .
Although there is no general consensus on the dangers of this type of radiation, the WHO warns that it is something very to take into account given that the rapid expansion of mobile phones has led to the need to investigate their development with a possible link between the emissions emitted by them and the formation of cancerous brain tumors. Each smartphone has its own degree of SAR emission , and it is important to know before proceeding to purchase a device that will accompany us every day.
Obviously, just as not all mobiles make the same photos, no smartphone emits the same amount of radiation as another. To find out, the ‘specific absorption rate’ is used ( HE ) that measures the amount of waves that a human tissue can hold since the issuance of your phone. The lower the SAR, the more secure the mobile is and the better it is for the user, as is the case with most terminals for sale in our country, but there are differences between mobile phones with low SAR radiation , and mobiles with high levels of SAR radiation .
It should be noted that the reduction of SAR radiation that our mobile phones emit is not only a marketing exercise, but also a task of social responsibility in order to preserve the health of the users as well as a contribution to a more sustainable world.
The European Union sets a limit of 2 W / kg, averaged over 10 grams of fabric and based on this we can determine which brands work best in this regard. If we look at the table that appears on these lines, we see that brands like Samsung, Google and LG they are the least SAR emissions they incorporate into their phones.
When it comes to talking about new smartphones to the market, we see how the LG G7 ThinQ manages to further reduce the emissions of the LG Q6, one of the smartphones that less SAR radiation they emit Accessing the updated SAR data we see how the new range top of LG reaches emissions of 0.24 W / Kg, thus becoming one of the best smartphones that we can buy today, and also with a radiation emission well below the standard.
On the opposite side of the scale we have the Chinese mobile phones Many times we wonder how Eastern manufacturers do it to reduce both the price of their terminals, and SAR radiation is one of the many explanations for this phenomenon. Just take a look at the list of mobile phones that more SAR radiation they broadcast to find a multitude of Chinese mobile phones at the top.
The smartphone that emits the most SAR radiation is the Xiaomi Mi A1 with 1.75 W / Kg, that is, almost 8 times more radication than the top of LG range. Next are the OnePlus 5T, with 1.68W / Kg, and then six Huawei mobiles, plus the OnePlus 5 and the Nokia Lumia 630. But not only do Chinese mobiles emit a high concentration of SAR radiation, as companies like Manzana They are also in this “top” with the iPhone 7, which is in position 11, and even the recent iPhone 8 introduced last year, which remains in the thirteenth position.
