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.

Cell phones emit radiofrequency (RF) waves, a type of non-ionizing electromagnetic radiation (commonly called “cell phone radiation”). When a consumer holds or carries a mobile device in close proximity, the user’s head and body can absorb over half of the transmitted energy.
The FCC’s inquiry into radiofrequency (RF) exposure limits and policies has generated broad response, as well as debate. Pong continues to play an active role in this process, weighing in on several topics of concern to users of cellphones and cases.

As cell phones and other wireless devices become increasingly popular, there is a growing concern over the possible health impact of wireless technology. Science is still inconclusive on whether cell phone radiation is safe or harmful to humans. Consumers are often confused by conflicting study results and mixed media messages. This article is intended to explain the primary causes of the scientific dilemma and offer some suggestions on how to interpret scientific findings in the field of cell phone radiation and human health.

As global cell phone subscription soared from 12.4 million in 1990 to 7 billion in 2013, cell phones have become a universal and indispensable tool for modern life.
Cell phones emit low-intensity radio-frequency (RF) energy, a type of non-ionizing electromagnetic radiation (EMR). When you hold your cell phone next to your head or wear it on your body, you can absorb over 50% of the transmitted RF energy. 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 mobile device landscape has dramatically changed during the past ten years. As a popular wireless technology, Wi-Fi uses the radio-frequency bands of 2.4 and 5 GHz for data exchange among wireless devices. Devices that transmit Wi-Fi signals are not just commonplace, they have become an essential part of our lives.
So, it’s only natural that the biological and health effects of these devices have become the subject of many on-going scientific studies. While the research community is performing scientifically rigorous studies and carefully weighing the evidence, five Danish ninth-grade school girls have taken matters in to their own hands.

Google Glass ushers in a new trend in wireless devices. A wearable computer with head mounted display, Google Glass captures a lot of attention with its design, functions and life-style implication. Though it is not yet on sale, some people have raised concerns that Google Glass introduces new types of radiation exposure risks due to the way in which it is worn. This article explores the implications of on-body wireless devices on radiation exposure.
Like all wireless devices, Google Glass emits electromagnetic radiation, called non-ionizing radiation, in the radio-frequency (RF) range in operation. The prototype Google Glass has Wi-Fi and Bluetooth antennas but no cellular antenna. Although there is still no consensus on whether this type of radiation is harmful to human body, growing scientific evidence shows correlation between wireless radiation and adverse health effects, including but not limited to brain tumors, impaired brain function, sperm damage and behavioral problems in children. In May 2011, the World Health Organization (WHO) classified radio-frequency electromagnetic radiation as “possibly carcinogenic to humans” based on increased risk of brain tumors.

According to a May 2013 news release in The Economic Times, India may ban import of mobile phones that don’t display their radiation emission levels in September 2013. The Directorate General of Foreign Trade (DGFT) will shortly issue a notification calling for mandatory disclosure of specific absorption rate (SAR) as a pre-condition for future handset imports.
In September 2012, Indian government issued a new mobile radiation law that lowered the exposure limit of mobile handsets from a SAR of 2.0 W/kg to 1.6 W/kg and made it mandatory for wireless device manufacturers to display the SAR values on their handsets.
To understand the rationale behind Indian government’s new regulation, let’s start by understanding what SAR is and what wireless radiation can do to us. Continue reading “Indian Government’s New Regulation on Wireless Radiation & Worldwide Call for Precaution”
On Jan. 21, 1993, the television talk-show Larry King featured a Florida man named David Reynard, who had filed a tort claim against the cell phone manufacturer NEC and the carrier GTE Mobilnet, claiming that radiation from their cell phones caused or accelerated the growth of a brain tumor in his wife Susan Elen Reynard.
“The tumor was exactly in the pattern of the antenna,” Reynard told King.

At Pong, we’ve been following recent scientific news with great interest. Israeli scientists have reported preliminary findings of a possible link between cell phone radiation and thyroid cancer.
Does Cell Phone Radiation Cause Thyroid Cancer?
Conducted at Beilinson Hospital in Petah Tikva and at Tel Aviv University, the Israeli research showed evidence for the first time of the possible connection between the rise in thyroid cancer cases to the increased exposure to radiation emitted by cell phones.

In June 2012, The Federal Communications Commission announced that it was going to take a closer look at its standards for cell phone safety to see if the agency needed to revise its 15-year-old guidelines. By November, Pong filed a letter with the Federal Communications Commission (FCC) asking the agency to “seek information on ways that the device testing guidelines can be improved to more accurately reflect predominant consumer behavior.”
