What is SAR?
SAR is the acronym of Specific Absorption Ratio, it indicates the amount of the electromagnetic radiation energy absorbed by the human body when exposed to radio waves.
In mobile phones, the SAR indicates the ratio of radiation absorbed by the soft tissue of the human head. The lower the SAR value is, the less radiation absorbed by the head tissue.
Does the SAR value harm to human health?
The debate about whether mobile phone radiation is harmful to human health has been accompanied by the development of mobile phones. Although there is no definite conclusion about whether mobile phone radiation will cause harm to the human body, there are still some international standards. For example, in the United States, the smartphone SAR value should be below or at 1.6W/kg. In Europe, the limit is at 2W/kg. Presently, there are about 58% smartphones on the market whose SAR value are below 0.6W/kg, which belongs to low radiation standard. So you needn’t to be so much worried about that.
Top 16 list of the phones emitting the most radiation
According to the top 16 smartphones list with the most radiation published by the German Federal Office of Radiation Protection, the highest SAR value of smartphones reaches 1.75W/kg, and it is Xiaomi Mi A1. Among the top 5 list, there are two Apple smartphones and 4 Xiaomi smartphones.
Top 16 list of the phones emitting the least radiation
According to the top 16 smartphones list with the least radiation, the lowest SAR value is only 0.17W/kg and the smartphone is Samsung Galaxy Note 8. There are 3 Samsung smartphones on the top 5 list.
But once again, please take it easy. As the SAR is the electromagnetic radiation rather than ionizing radiation (such as nuclear radiation). Whether the electromagnetic radiation will cause critical harm to the human body has not been determined. After all, the radiation of most home appliances like induction cooker, routers, microwave ovens is far higher than that of mobile phones. If you still worry about that, you can try not to sleep with your smartphone next to you.
