Specific Absorption Rate (SAR) is a measure of the rate at which energy is absorbed by the human body when exposed to radio frequency (RF) electromagnetic fields. In the context of mobile phones, SAR ratings help consumers understand the potential exposure to RF energy when using their devices. The Federal Communications Commission (FCC) in the United States has set a limit of 1.6 W/kg (averaged over 1 gram of tissue) for safe exposure to RF energy.
When comparing mobile phones with the lowest and highest SAR ratings, there is a significant difference in the percentage of the exposure limit that each phone reaches.
Lowest SAR Rated Phone: Mudita Pure Phone
The Mudita Pure Phone has the lowest Head SAR rating with a value of 0.07 W/kg, which amounts to only 4.38% of the FCC’s 1.6 W/kg limit. This low rating demonstrates that the device emits minimal RF energy, significantly reducing the potential exposure for users.
Highest SAR Rated Phone: Samsung Galaxy A13
In comparison, the Samsung Galaxy A13 has the highest SAR rating with a value of 1.27 W/kg. This represents 79.38% of the FCC’s limit, which is considerably higher than the Mudita Pure Phone. Although it is still within the safe exposure limit set by the FCC, the difference between the two devices is substantial.
The disparity between the lowest and highest SAR values is striking, with a 1714.29% difference between the Mudita Pure Phone and the Samsung Galaxy A13. This comparison highlights the importance of considering SAR ratings when choosing a mobile phone, especially for those concerned about potential health risks associated with RF energy exposure.
