How Do Cell Phone Cases Affect Your Radiation Exposure and Your Phone’s Performance?

The Environmental Working Group (EWG) has released a new report on the effect cell phone cases have on the amount of radiation your cell phone emits. The study speaks to the concern that cell phone cases can weaken the phone’s signal and actually increase the users’ radiation exposure as the phone tries harder to communicate.

The Environmental Working Group (EWG) has released a new report on the effect cell phone cases have on the amount of radiation your cell phone emits.  The study speaks to the concern that cell phone cases can weaken the phone’s signal and actually increase the users’ radiation exposure as the phone tries harder to communicate.

The Pong case was born out of our concerns around exposure to cell phone radiation and the effects it may be having on us.   Through countless hours of testing and work by our team of scientists, physicists, and engineers, we invented a technology that reduces cell phone radiation exposure while maintaining the device’s signal strength.

During research and testing we found that any cell phone cases can impact the radiation properties of a wireless device in an uncontrolled way.  Our research indicates that badly designed cell phone cases can partially block a phone’s antenna, making the device work harder to transmit signals.  This means that in those situations there may be potentially more radiation coming from the phone as it tries to maintain its signal.

Established in 1996, current FCC testing standards already account for accessories such as belt clips and holsters, which were pervasive in the 1990s, but not for cases, which did not exist then. Today, most consumers use cases, while belt clips and holsters are much less common.  Due to gaps in the FCC’s cell phone regulations, a phone worn right next to the body and enclosed by a case that obstructs the antenna could expose the user to more radiation than the FCC’s legal limit.

Pong urged the FCC to take into account cell phone cases during its compliance testing process to ensure that consumers are protected under normal operating conditions.  We have been concerned about this and we are happy to see that we are not alone.  The new article from EWG was done independent of Pong but resonates with Pong for concern on this issue.  EWG conducted its own research and drew data from published information including Pong’s filings to the FCC.

New Study Found Tripled Brain Tumor Risk for Long-Term Cell Phone Users

A 2014 Swedish study involving 1498 malignant brain tumor patients and 3,530 controls (people without a brain tumor) found an increased risk of malignant brain tumor associated with long-term use of cell phones and cordless phones. The study analyzed data from two previous studies with patients diagnosed between 1997-2003 and 2007-2009 in Sweden. The pooled analysis showed a clear trend of higher risk with longer wireless phone use. Specifically, the risk was 3 times higher for people who used wireless phones for 25 years or longer. The results resonate with a 2014 French study which found that heavy cell phone users (with 896 hours or more cumulative call time, or about half an hour daily use for 5 years) were 2-3 times more likely to develop a glioma (the most common type of malignant brain tumor), compared to non-regular users.

How to Understand and Find Specific Absorption Rate (SAR) of Your Mobile Device

Hi Pong Friends,

One of our most popular blog posts – How to Find the Specific Absorption Rate (SAR) of a Cell Phone – dates way back to October of 2012. Everyday, interested people find that article in the hopes of learning about SAR.

With that, we felt that the article needed updating to ensure everybody has the latest information. So, we tasked our resident expert Dr. Rong Wang to revisit her popular post and freshen it up with the most update-to-date SAR-related facts and figures for the newest devices.  Take it away to Dr. Wang:

How to Understand and Find Specific Absorption Rate (SAR) of Your Mobile Device

By Rong Wang, Ph.D.

What is SAR?

Cell phones and other mobile devices emit radiofrequency (RF) waves, a type of non-ionizing electromagnetic radiation (commonly called “cell phone radiation”). When you hold or carry a mobile device close to your head and body, you can absorb over half of the transmitted RF energy.

Cell phone radiation level varies from device to device and is measured by the Specific Absorption Rate (SAR). A mobile device’s SAR rating is used to estimate the maximum rate of RF energy absorption by a user’s head and body when using the device. In the United States, the Federal Communications Commission (FCC) sets the exposure limit for the general public to be an SAR level of 1.6 watts per kilogram (1.6 W/kg). A mobile device’s SAR rating must not exceed 1.6 W/kg in order to receive FCC certification and be sold in the United States. SAR is measured for placement of the phone next to the head and on the body. For example, the iPhone 6 has a Body SAR of 1.14 W/kg and Head SAR of 1.08 W/kg.

How to find the SAR of your device?

There are several ways to find the SAR rating of your device.  We have listed our top choices below.

From Manufacturers
Most manufacturers provide SAR information in their product’s manuals and on their websites. For example, the RF exposure of Apple devices can be found here http://www.apple.com/legal/rfexposure/

Mobile Manufacturers Forum
The Mobile Manufacturers Forum provides a database of SAR values for popular devices by Apple, LG, Motorola, Nokia, Samsung and Sony Ericsson.

The FCC
The FCC maintains a SAR database. To find the SAR rating of your device, you’ll need its FCC ID number. It’s usually shown somewhere on the case of your device or specified in the “About” data on the device itself. For some devices, you might have to remove its battery pack to find the number. Once you have the number, you can go to the FCC website and follow the instructions.

Other Sources
CNET maintains a list of the 20 cell phones with the highest SAR.

Is my cell phone safe?

While cell phones bring enormous convenience to our lives, the possible health consequences of exposure to cell phone radiation have aroused considerable public attention and scientific debate. The results of thousands of scientific studies are mixed and contradictory. The reported health effects include cancer, impaired brain and nervous functions, sperm damages, behavioral problems in children, to list a few. In May 2011, the World Health Organization (WHO) classified cell phone radiation as “possibly carcinogenic to humans”.  Read more in our blog to learn about cell phone radiation studies.

Just because your device’s SAR rating is below the regulatory threshold doesn’t necessarily mean it is safe. As a matter of fact, cell phones were introduced to the market without any safety testing on humans in the first place. Although the FCC enforces SAR limits on exposure, the standards have not been updated since 1996, and were based on a couple of animal behavioral studies in the 1970s. As of today, cell phones have been in widespread use for more than 15 years, and there is still extremely limited research data on its long-term health effects and the effects on children.

Furthermore, you may not be aware that the current FCC guidelines allow a device to be tested up to 25 mm away from the user’s body. Distance is a key factor in determining the amount of exposure from a device – the intensity of radiation increases rapidly as you get closer to the device. As a result, when you carry your device directly against your body, you may be exposed to radiation levels that exceed the device’s SAR rating and even the FCC exposure limit. For instance, if you place an iPhone 5 in contact with your body, your body exposure may exceed the FCC’s limit by more than 4 times. That’s why all cell phone manufactures include warnings in their user’s manuals to keep the cell phone a certain distance away from your body for safety concern. For example, you can find RF exposure information for Apple devices here. Apple even includes a proximity sensor in its iPhone 5S, 6, 6Plus and iPads to detect the presence of a user’s body and subsequently reduce the device’s transmitted signal in order to comply with the FCC’s RF exposure limit.

In March, 2013, the FCC commenced a formal Inquiry to determine whether there is a need for reassessment of the Commission radiofrequency (RF) exposure limits and policies.

How does a Pong Case affect SAR?

The Pong radiation redirection case offers a science-based solution to reduce the SAR of your device and therefore your RF exposure. Pong does not assert that cell phones are “unsafe” but believes that less exposure is better than more before we have a definitive answer. Pong’s built-in antenna technology reshapes the electromagnetic field pattern of your device’s transmitted signal to direct RF energy away from you while optimizing your device’s outbound signal. Specifically, micro-thin, gold-plated antennas, precisely engineered in size, shape and location, are imbedded in each Pong Case to achieve optimum coupling with the mobile device’s own antennas and maximum protection to you. Pong is the only technology proven in FCC-certified laboratories to reduce RF exposure. Pong’s claims were further verified by the Wired Magazine.

How to Minimize Cell Phone Radiation Exposure from DailyMom.com

Hi Pong Friends,

The Daily Mom isn’t in the pocket of big business, she’s just looking out for folks like you and me. Check out what she had to say about cell phone radiation.

HOW TO MINIMIZE CELL PHONE RADIATION EXPOSURE

There are nearly 7 billion active mobile subscriptions worldwide right now. This enormous number of cellular devices makes up over 95% of the population across the globe. With rising numbers everyday, it is predicted that soon there will be more active cell phones in the world than there are people. Wrap your brain around that one for a second!

As the world becomes overwhelmed by cell phones, so does our exposure to potential radiation dangers. Although research has come up inconsistent and inconclusive, there are concerns that the non-ionizing radiation that cell phones emit could be a possible cancer-causing carcinogen. (more)

Thanks,

Rob

Lebron James and Cellphone-Induced Salivary Gland Cancer

Hi Pong Friends –

Ben Greenfield over at BenGreenfieldFitness.com has been an advocate of living a life with reduced EMF exposure. In his article “How Lebron James’ Cell Phone Gave Him Mouth Cancer”, he references a recent recording by Evan Brand, host of the “Not Just Paleo” podcast.

Check it out what Ben had to say:

How Lebron James’ Cell Phone Gave Him Mouth Cancer 

A few weeks ago, I published the video “7 Ways To Reduce Electrical Pollution In Your Office“, and a couple weeks ago, the article “Is Your Mattress Killing You?”. Both addressed the concerning topic of what modern electronic signals are doing to our health.

Now i’s time to dig even deeper. The following guest post comes from Evan Brand, host of the “Not Just Paleo” podcast. Evan recently recorded a groundbreaking interview entitled EMF Solutions And How To Mitigate Cell Phone And Home Risks“ and it was so compelling, I asked him if he could expound upon it in this article. This is indeed a controversial topic, so if you have your own thoughts, comments or feedback, them leave them below this post.

Take it away, Evan…

Even if you aren’t an avid gossip magazine reader, surely you’ve heard about some of the extreme measures that celebrities are now taking for their health. Angelina Jolie and her breast removal surgery was the catalyst for me to dig deeper into the lives of celebrities and the things they promote.

Oftentimes, celebrity health issues simply don’t make sense. Their “random health problems” just seem so, well…random…and out of the blue to the general public.

But I am here to tell you these random health problems are not really random at all. Check out the rest of the article here.

Thanks,

Rob

Did You Know CNET has been tracking SAR data for 10+ years?

Hello Pong Friends,

It’s true, CNET has been on the SAR case for over a decade. Have a look at their informative article “Why CNET compiles cell phone radiation charts” by Kent German and see what their data says.

Why CNET compiles cell phone radiation charts

Earlier this week, Nate Ralph and I revived a portion of CNET’s long-standing cell phone radiation charts. The two galleries, the cell phones with the highest radiation levels and the cell phones with the lowest radiation levels, were quick to gather reader comments, a few of which I’d like to address here.
