In 2011, the World Health Organization  classified radio frequency radiation of the type used by WiFi devices as a Group 2B possible carcinogen. A study conducted by the University of Vienna have found WiFi exposures to cause genotoxicity as they break single and double strand DNAs in our body. This indicates that there are effects that may potentially surface with our future generations.
Unfortunately, the current state of cell phone radiation research is similar to the early days of tobacco research. It wasn't until 1999 when the U.S. Department of Justice finally filed a racketeering lawsuit against the major tobacco companies for engaging in a "50 year scheme" to counteract any scientific evidence that showed that cigarettes are harmful to a person's health. Is the potential cell phone cancer link the same sort of scenario? Are cell phone companies funding and promoting research that "proves" no link from cell phone radio radiation in an effort to discredit those studies that are uncovering problems?
Central to keeping the scientific argument going is making it appear that not all scientists agree. Again like the tobacco and fossil-fuel industries, the wireless industry has “war gamed” science, as a Motorola internal memo in 1994 phrased it. War-gaming science involves playing offense as well as defense: funding studies friendly to the industry while attacking studies that raise questions; placing industry-friendly experts on advisory bodies like the World Health Organization; and seeking to discredit scientists whose views depart from the industry’s.21
W. Kim Johnson, a retired physicist and past president of the New Mexico Academy of Science, reviewed the Aires web site for Discovery News and described the material as gibberish, saying that the authors "of the technical description of the ‘Aires' device reads like a random selection of technical terminology. The working description for this device is made up of jargon that, in the end, really says nothing."
Based on our results, it can be concluded that the bacterial strains used in this study respond differently to EMFs. These bacteria were capable of responding to environmental stresses that act by activating some specific systems such as ion channels, change via the membrane, DNA repair system, and probably ion efflux pumps in the membrane as well as interactions of molecules and antibacterial agents.  There are some ambiguities that need further investigations regarding answering questions such as which cellular mechanism is responsible for adaptation? Which factors are involved in alterations of antibacterial sensitivity? And subsequently, what are the differences in the response to radiation in gram-negative and gram-positive bacteria? Moreover, experiments on different bacterial strains with various electromagnetic fields should be performed in the future to better clarify these uncertainties.
In conclusion, although EMR exposure decreased the prolactin, estrogen, and progesterone levels in the plasma of maternal rats and their offspring, EMR-induced oxidative stress in the uteri of maternal rats increased during the development of offspring. Mobile phone- and Wi-Fi-induced EMR may be one cause of increased oxidative uterine injury in growing rats and decreased hormone levels in maternal rats. TRPV1 cation channels are the possible molecular pathways responsible for changes in the hormone, oxidative stress, and body temperature levels in the uterus of maternal rats following a year-long exposure to electromagnetic radiation exposure from mobile phones and Wi-Fi devices. It is likely that TRPV1-mediated Ca2+ entry in the uterus of pregnant rats involves accumulation of oxidative stress and opening of mitochondrial membrane pores that consequently leads to mitochondrial dysfunction, substantial swelling of the mitochondria with rupture of the outer membrane and release of oxidants such as superoxide (O2 -) and hydrogen peroxide (H2O2). The superoxide radical is converted to H2O2 by superoxide dismutase (SOD) enzyme. Glutathione peroxidase (GSH-Px) is an important antioxidant enzyme for removing lipid hydroperoxides and hydrogen peroxide and it catalyzes the reduction of H2O2 to water.
The FCC provides information about the specific absorption rate (SAR) of cell phones produced and marketed within the last 1 to 2 years. The SAR corresponds with the relative amount of radiofrequency radiation absorbed by the head of a cell phone user (47). Consumers can access this information using the phone’s FCC ID number, which is usually located on the case of the phone, and the FCC’s ID search form.

People who say cell phones are not safe cite peer-reviewed studies showing an association between cell phone use and tumor growth, DNA damage, and decreased fertility. They say cancers take 20-30 years to develop and cell phone studies have monitored periods of 10 years or less. They highlight the International Agency for Research on Cancer’s classification of cell phone radiation as a possible carcinogen. Read more background...

I used to keep my Bsnl wifi modem close to my bed and I saw lots of negative impact of it.I cannot sleep in time since I started using anroid phone and wifi. It’s very difficult for me to wake up early in the morning in time.I have become lazy and dull nowadays.I am not able to concentrate in anything properly.I cannot remember things.I forget to do many things .I feel that my brain has become very much inactive. I don’t feel like doing any works like in the past I was very active in doing my official works and other home works.two months back I came to know that I have a diabetic as well.give me some suggestion to live a healthy life and to make my brain more active .
The highest typical daily exposure, according to a study of 2009, came from cellphone base stations, cellphones and DECT cordless phones, with the highest exposure locations in trains, airports and buses.[17] The typical background power of electromagnetic fields in the home can vary from zero to 5 milliwatts per meter squared.[citation needed] Long-term effects of these electromagnetic fields on human and animal health are still unknown.
This paper presents the results of a replication study performed to investigate earlier Soviet studies conducted between 1974 and 1991 that showed immunological and reproductive effects of long-term low-level exposure of rats to radiofrequency electromagnetic fields (continuous wave 2450 MHz for 7h/day, 5days/week for 30 days). The RF exposure resulted in minor increases in formation of antibodies in brain tissue extract and the exposure did not appear to be pathological. In addition, a study was conducted to replicate a previous Soviet study on effects from the injection of blood serum from RF-exposed rats on pregnancy and foetal and offspring development of rats, using a similar animal model and protocol. Our results showed the same general trends as the earlier study, suggesting possible adverse effects of the blood serum from exposed rats on pregnancy and foetal development of intact rats, however, application of these results in developing exposure standards is limited.
This is a stupid article. We get electromagnetic radiation from radios, baby monitors, alarm systems, even the Earth itself. And even if we own none of that we still get it from out neighbors. It’s harmless, after all we been exposed to it forever from our planet. Unless you plan on wrapping yourself in foil you will escape it. Not that it matters, it does no harm in these low doses.

PURPOSE: MicroRNAs (miRNA) play a paramount role in growth, differentiation, proliferation and cell death by suppressing one or more target genes. However, their interaction with radiofrequencies is still unknown. The aim of this study was to investigate the long-term effects of radiofrequency radiation emitted from a Wireless Fidelity (Wi-Fi) system on some of the miRNA in brain tissue.
38. Does your child need that phone feature? Parental control apps allow parents to exert greater control over the features and functions their children can access on their smartphones. Making use of these apps and other tools to restrict access to the features you deem safe and appropriate can go a long way in keeping your kids safe while giving you much-needed peace of mind. “Determine what features your child needs based on his age. Does your 10-year-old really need web browsing capabilities?” – Laura Willard, Cell Phone Safety Tips for Kids, Tweens and Teens, SheKnows; Twitter: @SheKnows
In 2008, the most surprising news article reported that Dr. Ronald Herbermann, the director of the University of Pittsburgh Cancer Institute, advised his 3,000 faculty and staff to keep the cell phone away from the head by using a headset and to keep children from using cell phones except in emergencies. He cites unpublished scientific studies as the source of his concern.
This study investigated the long-term effects of low-level 2.45GHz MW irradiation (2h/day for 30 days)  on the reproductive function of male mice and its mechanism of action. Researchers observed that MW irradiation induced a significant decrease in sperm count and sperm viability along with the decrease in seminiferous tubule diameter, degeneration of seminiferous tubules, reduction in testicular 3β HSD activity and reduction in plasma testosterone levels. Increased expression of testicular i-NOS was observed in the MW-irradiated group of mice. These adverse reproductive effects suggest that chronic exposure to nonionizing MW radiation may lead to infertility via free radical species-mediated pathway.

The aim of this study was to investigate the possible protective role of selenium and L-carnitine on oxidative stress induced by 2.45-GHz radiation (60min/day for 28 days) in heart of rat. Electromagnetic radiation exposure was found to cause oxidative stress in the heart of rats. There is also an apparent protective effect of selenium and L-carnitine by inhibition of free radical formation and support of the antioxidant redox system.
Studies tell us that the biggest danger with WiFi radiation comes from nighttime exposures; cellular regeneration,rejuvenation, and detoxification is impeded. Notably melatonin production can be significantly reduced. If you really can’t bring yourself to remove your wireless router you can install a simple mechanical electrical timer (see attached image) on the socket where you plug your router in. Then just set it to turn the power off during sleep time.

“There is a carcinogenic effect,” announced Ron Melnick, the designer of the study. Male rats exposed to cell-phone radiation developed cancer at a substantially higher rate, though the same effect was not seen in female rats. Rats exposed to radiation also had lower birth rates, higher infant mortality, and more heart problems than those in the control group. The cancer effect occurred in only a small percentage of the rats, but that small percentage could translate into a massive amount of human cancers. “Given the extremely large number of people who use wireless communications devices, even a very small increase in the incidence of disease…could have broad implications for public health,” the NTP’s draft report explained.48

Now, what if I took that already precious treasure and stuck it in case that substantially increased the accumulation of value in one place by adding my driver’s license, MetroCard, ATM card, and credit card to the package? What if such a case made it possible to combine the pain of losing my phone with the inconvenience of losing my wallet in a brief moment of carelessness? We need not wonder, because that’s exactly what a wallet case does.
Intrinsically Safe Cell Phones and Intrinsically Safe Smartphones are starting to replace dedicated camera units. If you are wanting to consolidate devices and combine an Intrinsically Safe Camera with an Intrinsically Safe Cell Phone you now can. However, there still is a need for our clients in Oil & Gas, Manufacturing, Field Services, etc. that need that extra edge in their Hazardous Areas.
If you’ve bought a computer any time in the last 5 years, there is almost a certainty that it has wifi built in. We’re far past the days of getting separate wifi cards or adapters for our computers. The problem is, Wifi does emit RF radiation, a type of EMF radiation that is very harmful. Whether you have a desktop computer or a laptop that you use, it likely uses Wifi, so let’s take care of that.
But meanwhile know for certain that research is confirming that exposure to ICRW or Information Carrying Radio Waves, also called   wireless energy, can do all kinds of things from compromising immunity and causing the body to react by forming tumors to creating symptoms like headaches, trouble sleeping, anxiety and ringing in the ears. Other common sources of this same type of "non-ionizing radiation" include: cell phones, baby monitors, and computers and Smart Meters. Studies of symptoms from exposure to RF microwave(yes this EMF energy goes by many titles!) include heart racing, tingling sensations, numbness, dizziness, and fatigue. 
And David Carpenter, M.D., director of the Institute for Health and the Environment at the University at Albany, says that while exposure from a single router in your home may be small, the risks could be greater in places that have dozens of laptops and routers working at the same time—such as school classrooms. Phillips notes that children’s developing bodies may be more vulnerable to all forms of radiation from devices.
Joel Moskowitz (@berkeleyprc) of the University of California, Berkeley School of Public Health, US, says: “This is the largest technological experiment in the history of our species, with potential health risks we still know next to nothing about.” This view is shared by Denis Henshaw, professor of human radiation effects at Bristol University, UK, who said: “Vast numbers of people are using cell phones and this could be a time bomb of health problems.”
