Is using a cell phone safe? Learn about SAR ratings.


The first step in cell phone radiation protection is identifying the specific absorption rate of your specific device. According to the Cellular Telecommunications Industry Association (CTIA), specific absorption rate, or SAR, is "a way of measuring the quantity of radio frequency (RF) energy that is absorbed by the body." This amount can vary from cell phone to cell phone.

According to a piece by, a phone's maximum SAR level must be less than 1.6 watts per kilogram in order to pass Federal Communications Commission (FCC) standards. Canada follows the same standard while countries in Europe allow up to 2W/kg.

Is SAR a reliable measurement?

While the SAR rating does provide a basis for analysis and evaluation, it is far from completely uncontroversial. For example, while phones will list their FCC SAR rating, it's impossible for this number to take into account varying transmission bands as well as the differences in a human body from person to person

As the CNET piece points out, while conclusive tests associating cell phone radiation and cancer in humans have not been determined, research has proven that cell phone radiofrequency (RF) could be a major factor in the acceleration of cancer in laboratory animals.

Should I be concerned about radiation from my phone?

While there is still no concrete evidence proving causation between cell phones and harmful health risks, there is certainly correlation that should make you stop and consider the potential consequences. For all the people (mostly lobbyists on that side of the industry) yelling about inconclusive evidence proving health risks, there is the same number of inconclusive results in proving that they're harmless. However, cell phones have been found to affect internal pacemakers.

One of the simple things you can do if you're concerned about cell phone radiation protection is to invest in a cell phone that has a lower SAR rating. Anything above 1.0 is generally considered high in potential radiation levels.

Regardless of what's currently been proven or not, it's not a bad idea to consider consider more cell phone radiation protection going forward. Most people on both sides typically agree that exposing yourself to an exorbitant amount of radiation is not a good idea and you never know what the next study might find.

  • First, you can choose a cell phone that has a low SAR reading to lessen your SAR exposure.
  • Second, Shield yourself. A Bioelectric Shield will deflect a significant portion of SAR.
  • Finally, add specific protection on every radiation item you own. We have several additional EMF protection devices that can be placed on any type of radiation producing device including your cell phone and headset.  By doing all three actions, your risk should be minimal.
