Knowledge Base | What are SAR Ratings & Safety Values for Cell Phones

Specific Absorption Rate (SAR) – Cell Phone Safety Info

SAR is a way of measuring the quantity of radio frequency (RF) energy that is absorbed by the body.  It can also refer to absorption of other forms of energy by tissue, including ultrasound. Cell phone safety means lower your cell phone SAR, the lower your electromagnetic radiation exposure and therefore potential health risks associated with using your cell phone. 

In North America, a cell phone SAR’s rating is measured between 0.0 and 1.60 with 1.60 set by the Federal Communications Commission (FCC) as the maximum level of radiation permissible. The Cellular Telecommunications Industry Association (CTIA) requires all cell phones in the U.S. to comply with this SAR limit from the FCC. 

In Europe, the SAR rating runs from 0.0 to 2.0 as adopted by the European Union Council and recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).  In North America, SAR is measured in watts per kilogram (or W/kg) averaged over one gram of biological tissue while in Europe SAR is averaged over 10 grams. The FCC limit, which averages over one gram of body tissue, is much stricter than the rest of the world. 

In addition to proactively selecting a cell phone with a low SAR rating, you can also reduce your body’s radiation exposure by holding your phone in the patented pocket found in many of SportPort™ active wear pieces. Keeping your cell phone ON you is important to our need to work, stay connected to family or for personal security. SportPort wants you to have cell phone safety be part of your healthy lifestyle too.
