If you are concerned about the possible health effects of radio wave radiation emitted by your cell phone, your options are simple and cheap. This kind of radiation is at its highest levels nearest the antenna. Also, not all cell phones are created equal. Sar Shield offers a useful radiation chart for cell phones that provides an accurate "Sar rating" for every cell phone model. It's important to realize that at these low radiation levels, if you keep the cell phone away from your head and body, you are perfectly safe. However, if you'd rather not use a headset, then there are plenty of resources to obtain a radiation shield for your phone.

And yet, a lot of people do use these, including people I know and respect. I see people on the subway playing Candy Crush, the cover of their folio-style wallet case folded back, all of their cards just flapping in the wind. And don’t just take my word for it: The Silk iPhone wallet case has nearly 2,000 reviews on Amazon with an average score of 4.5 stars. People not only use these cases—they love them!
One thing I am totally shocked by is the resistance that people seem to have to believing that something that promotes “Convenience” for them, could be dangerous. I am Electromagnetic Hypersensitive and I am involved with numerous groups of people worldwide who are suffering from the detrimental effects of wireless radiation. These groups are growing substantially as people become more and more aware that their health issues can be traced back to consistent exposure to microwave radiation that has NO proven record or research to prove its safety. From my own experience, placed in a Wi-Fi field, every muscle in my body contracts like I’m being electrocuted, lumps begin to form from the effect of blood thickening, I get massive headaches, chest pain (the heart struggling due to sticky red blood cells), and eventually total paralysis from the severe fatigue that even makes it hard to breath. So many people are suffering from illnesses they haven’t even traced back to Wi-Fi but if they succeed at globalizing it, I’m sure you’ll all find out eventually as you accumulate the effects. Thank you Dr Edward Group for posting this invaluable information.
Purpose: This article is a systematic review of studies on the effects of non-ionizing radiation at the microwave (MW) frequency of 2.45 GHz (2450 MHz), which is predominantly used in WLAN/Wi-Fi applications (wireless local area network) and microwave ovens. Newer WLAN standards also use the frequency ranges of 5 GHz, 6 GHz, and 60 GHz. WLAN, referred to generically in this review also as Wi-Fi, has become the technology of choice for many wireless applications because providers do not require a license, making the service free to users. To meet users’ desire to be online all the time, more and more WLAN antennas (access points, femtocells, routers) emitting pulsed 2.45 GHz radiation are being installed at libraries, hospitals, hotels, airports, railway stations, shopping malls, public places, and in buses, subways, and passenger trains. Wi-Fi consoles are used to play games. Office and household appliances are also fitted with Wi-Fi antennas. Residential routers often contain two Wi-Fi transmitters. As part of its digital learning initiative, the German Conference of Ministers of Education has decided to provide all schools with Wi-Fi networks. The extensive body of research on the health risks of Wi-Fi radiation is generally not considered by policy-makers or in the public debate.
The cell phone pocket shield allows you to use your earbuds or headphones during a call but at the same time, safely place your cell phone in your pocket, purse, etc. This means you are protected both when the phone is connected on a call or sitting idle. The shield will not interfere with your cellular signal and will not negatively affect battery life.
The most compelling evidence though comes from a Swedish team of cancer experts whose research stretches back 15 years. The results clearly demonstrate “a consistent association between long-term use of cell phone and cordless phones and glioma and acoustic neuroma”. Overall, they found that using a cell phone for more than a decade significantly increases the risk of a malignant tumour by almost two times with an analogue cell phone and by nearly four times with a digital phone. Interestingly, the risks were even higher for people who had started using mobiles as teenagers.
