Recent research has resurfaced concerns among scientists about a potential link between cell-phone radiation and cancer. But that research—a 10-year, $25 million government study in rodents—left a lot of key questions unanswered. That includes how relevant the findings are to newer wireless technologies such as Bluetooth and WiFi that have become widespread since the study was designed in the early 2000s.
Conclusions: Based on the extensive body of research and the adverse health effects demonstrated in the majority of the studies, it is recommended that steps should be taken to minimize RF radiation exposure in accordance with official recommendations. Wired solutions should be given preference. Current exposure limits and SAR values do not protect from health risks associated with Wi-Fi radiation. The adverse effects on learning, attention, and behavior serve as a basis for educational institutions of all age groups to forgo the use of Wi-Fi applications. Due to cytotoxic effects, Wi-Fi technologies are not suitable for hospitals and telemedicine. Wi-Fi technologies should not be used in bedrooms, work spaces, common lounges, hospital rooms, lecture halls, classrooms, and public transport. The possible risks associated with Wi-Fi radiation could be avoided by testing alternative technologies at other frequency bands like optical VLC/Li-Fi technologies (visible light communication). When Wi-Fi cannot be avoided as a transition solution, the ALARA principle must be applied: no continuous transmission, instead Wi-Fi networks that can be turned off and feature dynamic power management.

The present study was designed to determine the effects of 2.45 GHz radiation (1, 2, 12, or 24 hours) on the antioxidant redox system, calcium ion signaling, cell count and viability in human leukemia 60 cells.The extent of lipid peroxidation, cytosolic free Ca²⁺ and cell numbers were higher in 2.45 GHz groups than in the controls and was time-dependent. 2.45 GHz electromagnetic radiation appears to induce proliferative effects through oxidative stress and Ca²⁺ influx although blocking of transient receptor potential melastatin 2 channels by 2-aminoethyl diphenylborinate seems to counteract the effects on Ca²⁺ ions influx.
5. “Claw” your fingers around your phone. “This tight grip will make it harder for anyone to snatch your phone out of your hands. Not sure how to master the claw? No worries! CNET gives a great explanation: ‘Grip the phone securely in your hand, fanning out your fingers so that you’ve formed a protective cage or claw around the phone.’ For even more claw-like protection, you can weave your fingers around the device.” – Kyle Therese Cranston, 4 Tips for Keeping Your Cell Safe on Public Transportation, Edenred Commuter Benefit Solutions; Twitter: @CommuterBenefit
Also, every inch you put between yourself and your Wi-Fi router significantly lowers the strength of the radiation your body encounters. “Put it this way,” Foster says. “During a call, your mobile phone is transmitting steadily at a strength maybe 100 times more powerful than Wi-Fi, and you’re holding the phone right against your head, and we still don’t find any health issues with that level of exposure.”
I really want to caution you to be careful of any "expert" or EMF blogger recommending anti-radiation filtering cases, stickers that attach to the phone or necklaces to "ward off" EMF. I get it, when I first realized 25 years ago that I was sensitive to electromagnetic energy and then later, when I understood that without a doubt, man made electromagnetic radiation has a biological effect on my body, I wanted an easy fix. I tried the shielding materials and cases and I just did not feel any better. Then I bought meters to see if the energy changed and I actually noticed what the California Department of Health now says and it's what the FTC and FCC post warnings about: "Some shielding materials can make exposures worse". So please, be careful and read on for what you can do to avoid electromagnetic radiation exposure.
This study measured the levels of blood lipid peroxidation, glutathione peroxidase, reduced glutathione, and vitamin C to follow the level of oxidative damage caused by 2.45 GHz electromagnetic radiation exposure (60 min/day for 28 days) in rats. The possible protective effects of selenium and L-carnitine were also tested and compared to untreated controls. Researchers found that 2.45 GHz electromagnetic radiation caused oxidative stress in blood of rat. L-carnitine seems to have protective effects on the 2.45-GHz-induced blood toxicity by inhibiting free radical supporting antioxidant redox system although selenium has no effect on the investigated values.

If you use a USB Wi-Fi adapter (for PCs that don’t have a built in wireless network interface card) use it on a USB extension cable (10 feet or more). The same goes if you use a 3G or 4G USB internet stick, or dongle, to connect to the Internet while you’re traveling. A USB extension cable will significantly reduce your exposure. Tip: the further the USB internet stick is from you when you’re surfing the Web, the less you will be exposed. Buy a USB extension that’s a good 10 to 15 feet long.
Numerous peer-reviewed studies have found that cell phone use is not associated with an increased risk of brain tumors. An Oct. 20, 2011 study of 358,403 Danish citizens – the largest study of its kind to date – concluded that "there was no association between tumors of the central nervous system or brain and long term (10 years +) use of mobile phones."  A July 27, 2011 study found that there was no association between cell phone use and brain tumor risks among children and adolescents.  Numerous other studies published from 2001-2013 have similarly concluded that there is no association between cell phone use and the development of brain tumors.      
This study examined the possible ability of 2.45 GHz microwave radiation exposure (30 min) to modify the expression of genes that codify heat shock proteins (HSP) in the thyroid gland. Ninety minutes after radiation, HSP-90 and HSP-70 had decreased significantly (P<0.01); Twenty-four hours after radiation, HSP-90 had partially recovered and HSP-70 had recovered completely. There were few indications of lesions in the glandular structure and signs of apoptosis were negative in all radiated animals. The results suggest that acute sub-thermal radiation at 2.45 GHz may alter levels of cellular stress in rat thyroid gland without initially altering their anti-apoptotic capacity.
Whether you call them cell phones, smart phones or mobile devices, it seems like everyone has one. According to the wireless telecommunications industry, the U.S. now has an estimated 300 million mobile subscribers, compared to 110 million subscribers a decade ago. The increase in cell phone use has generated concern about possible health risks related to radiofrequency electromagnetic fields from this technology, and a market for shields as possible protection against the radio waves the phones emit. The Federal Trade Commission (FTC), the nation's consumer protection agency, has some practical tips to help you avoid scams and limit your exposure to electromagnetic emissions from your cell phone.
Because these are complex diseases that develop over decades, it is difficult to conclusively show that the increase in wireless signal exposures directly cause the diseases. International Agency for Research on Cancer (IARC) considers wireless radiation as a class 2B possible carcinogen due to limited evidence. These small number of studies are leaning towards showing that electromagnetic radiations, including WiFi, are not safe.
The legislators themselves say that no link has been demonstrated (Le Monde reports them as having been unable to identify ‘a causal link between the biological effects described on cellular models, animals or humans and possible health effects that result.’) and there is only limited evidence (one study, unconfirmed by any others) to suggest risk even for intensive users of mobile phones.
I wish I could do the same thing, but I cannot demand that my neighbors turn off their Wi-Fi. They have ipods, iphones and ipad, other neighbor is using a laptop and I have new neighbors (since a 3/4 of a year or so) that have their pc next to my bedroom. I thought I was going crazy, I never got any true rest, even after sleeping for 8+ hours. I never have that feeling that your body actually got some rest and your mind feels refreshed.. now the days just flow into eachother and it feels like a neverending nightmare. I stumbled across the reason what could be the cause by sleeping over at my mom’s place. She has her router in the middle of her livingroom and has been complaining about suffering from fatique for over 6 years. Also irratic heartbeat, headaches, feeling of despair and other symptoms. She’d been at the doctor’s but they could never establish a cause. Just to try something I turned off her router(which had Wi-Fi) and began to realize all the “tension” I felt inside my head started to fade away and when looking inside the room I could almost “feel” the objects again and that moment I asked my mother how she felt and she told me “somehow I feel a lot lighter and my headache seems to go down” From that moment on I’ve become aware of the danger that Wi-Fi has influenced my every day life. Some people have no problems while others are almost pariahs since the people not feeling anything do not understand what we are going through. Sorry for the long read but I just want to let other people know they are not alone. Even if it feels like it. I think another symptom is making people extremely introverted and insecure. I hope the authorities will start taking action soon because I cannot live like this for another 10 years. Hugs for everyone.
Recall bias, which can occur when data about prior habits and exposures are collected from study participants using questionnaires administered after diagnosis of a disease in some of the participants. It is possible that study participants who have brain tumors may remember their cell phone use differently from individuals without brain tumors. Many epidemiologic studies of cell phone use and brain cancer risk lack verifiable data about the total amount of cell phone use over time. In addition, people who develop a brain tumor may have a tendency to recall cell phone use mostly on the same side of the head where their tumor was found, regardless of whether they actually used their phone on that side of the head a lot or only a little.
Thirty-two rats and their forty newborn offspring were divided into the following four groups according to the type of EMR exposure they were subjected to: the control, 900, 1800, and 2450 MHz groups. Each experimental group was exposed to EMR for 60 min/day during the pregnancy and growth periods. The pregnant rats were allowed to stand for four generations (total 52 weeks) before, plasma and uterine samples were obtained. During the 4th, 5th, and 6th weeks of the experiment, plasma and uterine samples were also obtained from the developing rats. [The electric field density was set at 20 dB and 11 V/m in order to obtain 0.1 W/kg whole-body average specific absorption rate (SAR).]
1. Be careful what you share. “Use the same good sense about what you post from your phone as from a computer. Once they’re posted, text, photos, and video are tough to take back, can be copied and pasted elsewhere, and are up there pretty much forever. Think about the people in them (including you!). Reputations are at stake.” – Tips for Smart Cellphone Use, Connect Safely; Twitter: @ConnectSafely
