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.
With worldwide mobile subscriptions estimated to be around 7 billion in 2014, cell phones have become a universal and indispensable tool for modern life. With a cell phone, you can talk to anybody on the planet from almost anywhere. But do you really know how your cell phone works?
In the most basic form, a cell phone is essentially a two-way radio, consisting of a radio transmitter and a radio receiver. When you chat with your friend on your cell phone, your phone converts your voice into an electrical signal, which is then transmitted via radio waves to the nearest cell tower. The network of cell towers then relays the radio wave to your friend’s cell phone, which converts it to an electrical signal and then back to sound again. In the basic form, a cell phone works just like a walkie-talkie.
In additional to the basic function of voice calls, most modern cell phones come with additional functions such as web surfing, taking pictures, playing games, sending text messages and playing music. More sophisticated smart phones can perform similar functions of a portable computer.
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.
Your mobile phone is smart. Now the case for your mobile device can be, too.
Pong Research introduces the world’s first Intelligent Case. The Pong Case pairs with your device to redirect wireless energy for optimized protection and performance.
All mobile devices use radio-frequency (RF) electromagnetic waves to communicate. The devices contain antennas to transmit and receive wireless signals. Unlike traditional cases, the Pong case is embedded with a custom-engineered antenna system that passively interacts with your device when you snap it on. Specifically, copper elements plated in gold, yet thinner than a human hair, are precisely engineered in size, shape and location, to achieve optimum coupling with the mobile device’s own antenna. Pong’s built-in antenna technology reshapes the electromagnetic field pattern of your device’s transmitted signal and directs wireless energy away from you while optimizing your device’s outbound signal.
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.
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.
