The wireless industry has sought to downplay concerns about cell phones’ safety, and the Federal Communications Commission has followed its example. In 1996, the FCC established cell-phone safety levels based on “specific absorption rate,” or SAR. Phones were required to have a SAR of 1.6 watts or less per kilogram of body weight. In 2013, the American Academy of Pediatrics advised the FCC that its guidelines “do not account for the unique vulnerability and use patterns specific to pregnant women and children.” Nevertheless, the FCC has declined to update its standards.30
If you’re thinking of buying a phone case with ‘radiation blocking material’ believing it will reduce radiation, you should know this: Phones have automatic power control, such cases act as shields  and make the phone work harder, transmitting more power, increasing heat and reducing battery life, The incoming signal to the phone will also be reduced so your phone may not work in areas of poor signal.
When Carlo arrived, he was met by two seriously muscled men in plain clothes; the larger of the two let drop that he had recently left the Secret Service. The security men steered Carlo into a holding room, where they insisted he remain until his presentation. When summoned, Carlo found roughly 70 of the industry’s top executives waiting for him in silence. Carlo had spoken a mere 10 minutes when Wheeler abruptly stood, extended a hand, and said, “Thank you, George.” The two muscle men then ushered the scientist to a curbside taxi and waited until it pulled away.13

An analysis of data from NCI's Surveillance, Epidemiology, and End Results (SEER) Program evaluated trends in cancer incidence in the United States. This analysis found no increase in the incidence of brain or other central nervous system cancers between 1992 and 2006, despite the dramatic increase in cell phone use in this country during that time (22).
In the current study, the pattern of the response of E coli to Wi-Fi and RF simulator radiation was identical. The maximum differences in the diameters of inhibition zones were observed between 6 and 9 hours of the bacterial exposure to radiation (Figures 1 and 2). After 12 hours of exposure, the bacterial responses to radiation as a stressor led to returning to the preexposure status.
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.
There is no clearly-defined safe distance as this new issue has yet been studied enough. While EMF emissions from different routers vary, for most home WiFi routers, a distance of 40 feet (ideally, or 10 feet at a minimum) will help your body and shouldn’t impact your WiFi connection too much. And beware that radiation from WiFi routers can pass through the walls in your home so keep this in mind as you evaluate the safety of your bed's location. Those who are sensitive to EMFs should take extra efforts to reduce EMFs and chronic proximity to the sources.
The wireless communications industry is rushing to blanket the nation with next-generation networks whose health effects are unknown. Despite studies linking radiation from existing networks to cancer in lab animals, the Federal Communications Commission and state legislators are bowing to industry lobbyists and clearing the way for the new networks.  

Brain Fog – or cognitive decline, it is noticeable when you feel that your memory has been declining, or you’re having trouble recalling names, or places or events. It is also noticeable if you are having a tough time concentrating. Some scientists believe that the dramatic rise in Alzheimers Disease can be partially attributed to EMF damage and our wireless age.
“It’s because WiFi is just a low frequency sound wave.” For me, the jury is still out concerning the link between WiFi and sleep disturbance. But I’m sorry, you are wrong about WiFi being a low frequency sound wave. It is a radio wave, i.e. electromagnetic, and it runs at 2.3 GHz and/or 5 GHz, which cannot by any stretch of the imagination be described as low frequency.
“There are 25,000 brain tumor cases in India’s Andhra Pradesh and Telangana states, and most of them are attributed to excessive use of cell phones, as per a recent medical survey”. Girish Kumar said that World Health Organization warned of increasing risk of cell phone brain tumor and cancer cases caused by the use of cell phones and location of cell towers in residential areas.
