Samsung adopted an innovative antenna system in 2006 to “enhance handset safety by radiating most of the transmitted RF energy away from the handset user” and improve RF (radio frequency) performance.
Searching for a way to lower radiation exposure based off the FCC’s SAR guidelines sounds like the smart, responsible and educated thing to do—right? Think again! This post points out several shortcomings of the general acceptance of safety guidelines being thermally based and not addressing actual microwave radiation exposure at below thermal levels.

It’s a good idea to research which Smartphone has the lowest SAR before buying yourself or loved-one a high frequency microwave transmitter that is carried next to the body all day; and from an RF design perspective, Samsung stands out as the only manufacture striving to make lower levels of radiation exposure a Smartphone design priority.
The Samsung Galaxy Note 5, Model SM-N920V (for Verizon) ranks well among popular Smartphones as the lowest SAR Smartphone with a Head SAR Level of only 0.21 W/kg (watts per kilogram averaged over one gram of tissue). However, there is a lot more to phone radiation safety than SAR levels alone!

Cell phones sold in the USA vary in terms of their Specific Absorption Rate or SAR, the Federal government’s measure of the maximum amount of microwave radiation absorbed by the head or body.
The FCC requires all cell phones sold in the USA must not exceed a maximum SAR of 1.6 watts per kilogram averaged over one gram of tissue. Official documents show the FCC is under pressure from doctors and scientists who insist current guidelines are not enough. See Reassessment of Federal Communications Commission Radio-frequency Exposure Limits and Policies” (Proceeding Number 13-84).
Most critical shortcomings of SAR testing need to be understood
- A cell phone’s SAR is assessed using an artificial laboratory model of a very large adult male.
- Does not consider women, children or prenatal exposure
- The lower the SAR, the less the user is exposed to thermal levels of microwave radiation.
- Does not consider non-thermal ROS effects linked to DNA damage.
Common sense suggest less exposure to cellphone radiation is better, and the cautious thing to do is own a phone with the lowest SAR rating. Your attention should be on Samsung at this point because they make 12 of 20 lowest SAR Smartphones. This makes a very substantial difference, users of the twenty highest SAR cell phones in the USA can absorb several HUNDRED times more radiation in their heads than users of the twenty lowest SAR smartphones.
For example, the Samsung Galaxy Note 3 N900V made for Verizon has an FCC measured SAR of only 0.35 W/kg (watts per kilogram). while an Apple iPhone 6 Plus exposes a user’s head to a whooping 1.19 W/kg. That’s a 340% increase from highest to lowest on these high-end smartphone devices.

Samsung was able to do this because of regulatory ground work done by Silicon Valley start-up Vortis Technology. Under the leadership of Vortis CEO, Jim Johnson, Vortis led-the-way for changing an out-dated FCC rule on July 10, 2003, which had long forced cellphone companies to use antenna’s that transmitted 360 degrees, transmitting isotropically, known as omnidirectional in the wireless industry.
After the FCC’s isotropic rule was changed so hearing aids would not be disrupted by phone radiation — Samsung went into R&D mode, leading to an innovative antenna system three years later in 2006, in their words, “enhances handset safety by radiating most of the transmitted RF energy away from the handset user” (more energy from back of phone) and improved RF (radio frequency) performance.
Through most of the smartphone era, Samsung has consistently produced the lowest SAR cell phones. So, why haven’t more manufacturers adopted modern antenna technologies that both improves user safety and enhances cell phone performance?
The answer is simple, no-one is forcing them to change the way their phones transmit radiation. While higher-res displays and better software and hardware reap instant return on investment– the wireless industry fears making phones safer leaves open the idea that current technology may not have been safe to begin with, and that’s not going to fuel holiday sales.
Many health researchers have questioned the utility of assessing only a cell phone’s SAR, this is all that governments currently regulate. Throughout the world, governments want the public to believe that all legally marketed cell phones are safe, and that a cell phone’s SAR doesn’t matter as long as it meets their certification test.
The SAR standards, however, were developed decades ago to protect users only from the acute effects of the heat generated by microwave radiation, and do not protect users from non-thermal effects of cell phone radiation which may cause harm from long term exposure including increased brain cancer risk and sperm damage.
None of the lowest SAR phones are made by the leading U.S. companies, Apple, Motorola, or RIM Blackberry.
In contrast, thirteen of the twenty highest SAR phones are sold by U.S. companies (eight Motorola and five RIM Blackberry), and none are sold by Samsung.
- The Samsung Galaxy Note 2 smartphone has a maximum SAR of 0.17 W/kg (watts per kilogram).
- The SAR for the Apple iPhone 4S is 1.11, and for the Motorola Droid Razr Maxx, it is 1.54 W/kg.
Cell phones made by American and Canadian companies have the highest SAR ratings in the world, thus subjecting users to the highest absorption rates of microwave radiation exposure . It’s time for U.S. companies to compete in terms of improving user safety.
Moreover, Samsung has demonstrated that enhanced antenna technology can improve cell phone performance while it reduces microwave radiation absorption in the user’s head and body.
So adoption of this technology is a “win-win” for both the industry and the consumer. But that isn’t what’s happening! When will Vortis Technology be available inside cell phones to make cell phones safer?
The cell phone industry is going the other way, they have been lobbying to weaken the U.S. standard because the ICNIRP or international standard allows up to 2.0 watts per kilogram averaged over ten grams of tissue.
This may sound like a trivial difference, it is not because measuring radiation absorption over a larger volume of tissue averages out the “hot spots.” Adoption of the ICNIRP standard in the U.S. could triple the amount of cell phone radiation absorbed by Americans.

Since 1997, twenty-two declarations have been signed by scientists and health professionals calling for stronger cell phone radiation regulations. See Dr. Magda Havas’ website for a list of all 22 resolutions at http://bit.ly/XyeM46.The American Academy of Pediatrics, a professional organization representing 60,000 physicians, sent a letter to the FCC and the FDA urging the FCC to adopt radiation standards that (http://bit.ly/17tQclg):
- “Protect children’s health and well-being … Current FCC standards do not account for the unique vulnerability and use patterns specific to pregnant women and children. It is essential that any new standard for cell phones or other wireless devices be based on protecting the youngest and most vulnerable populations to ensure they are safeguarded throughout their lifetimes.
- Reflect current use patterns. The FCC has not assessed the standard for cell phone radiation since 1996 … Many children, adolescents and young adults, now use cell phones as their only phone line and they begin using wireless phones at much younger ages. Pregnant women may carry their phones for many hours per day in a pocket that keeps the phone close to their uterus. Children born today will experience a longer period of exposure to radio-frequency fields from cellular phone use than will adults, because they start using cellular phones at earlier ages and will have longer lifetime exposures. FCC regulations should reflect how people are using their phones today.
- Provide meaningful consumer disclosure. The FCC has noted that it does not provide consumers with sufficient information about the RF exposure profile of individual phones to allow consumers to make informed purchasing decisions. The current metric of RF exposure available to consumers, the Specific Absorption Rate, is not an accurate predictor of actual exposure. AAP is supportive of FCC developing standards that provide consumers with the information they need to make informed choices in selecting mobile phone purchases, and to help parents to better understand any potential risks for their children. To that end, we support the use of metrics that are specific to the exposure children will experience.”
FACT: Users of the twenty highest SAR cell phones sold in the U.S. can absorb up to four times as much radiation in their heads as users of the twenty lowest SAR cell phones.

- A mobile phone compliant with the ICNIRP standard of 2.0 W/kg SAR in 10 g of tissue may lead to a 2.5 to 3 times excess above the FCC standard of 1.6 W/kg in 1 g of tissue (i.e., 4-5 W/kg in a cube of 1 g of tissue)'(Gandhi and Kang, 2002).” (cited in Gandhi et al.

- James Lin of the University of Illinois, Chicago, who was recently appointed a member of ICNIRP, has called this proposal to increase the averaging volume from 1g to 10g ‘scientifically indefensible’
(see MWN, J/A00 and N/D00).
- According to Lin, a limit of 2.0 W/Kg averaged over 10g would be approximately equivalent to an SAR of 4-6 W/Kg, averaged over 1g (see MWN, S/O01 and M/J03).
