The purpose of this study was to reveal whether long term exposure (over a year) of 2.4GHz frequency RF radiation will cause DNA damage of different tissues such as brain, kidney, liver, and skin tissue and testicular tissues of rats. Based on the DNA damage results determined by the single cell gel electrophoresis (Comet) method, it was found that the % tail DNA values of the brain, kidney, liver, and skin tissues of the rats in the experimental group increased more than those in the control group. The increase of the DNA damage in all tissues was not significant (p>0.05), however the increase of the DNA damage in rat testes tissue was significant (p<0.01). In conclusion, long-term exposure to 2.4GHz RF radiation (Wi-Fi) does not cause DNA damage of the organs investigated in this study except testes indicating that testes are more sensitive organ to RF radiation.
I had a wireless router installed about a month ago, since then I have had trouble sleeping and also it was like something was inflaming my brain (don’t know how else to describe it). I stumbled onto the discussion about WiFi and problems associated with it and decided to turn off the WiFi on my router and just go with a wired connection. Instantly the pressure on brain was gone, its like my brain began to relax once the wireless was off. How can they say there is no evidence?
c) and before you raise the argument that visible light is itself electromagnetic radiation, with even shorter wavelengths than microwaves, electromagnetic radiation within the visible light range does not penetrate living cells and other molecular materials as X-Rays (ionising radiation) or microwaves (non-ioninsing radiation) do. Practically all visible light is reflected by our bodies, and therefore it’s energy is not absorbed by our cells and is therefore harmless.
Most phones have a GPS that can pinpoint your general or exact location. With this capability, many applications may collect and share your location information. However, many smartphones give you the option of managing your location sharing under the “settings.” You can pick and choose which applications may access your location or you can opt to turn off the location setting altogether. Minimizing the location access can also help increase the battery life on your phone. If your phone doesn’t offer specific location-sharing settings, choose carefully when downloading new apps so you’re not sharing your location unknowingly.

As I demonstrate in the video, you can see that with this router, I am exposed to about 100 times more Radio Frequency (RF) energy when I’m next to the router versus standing 20 feet away. This measurement video, like the others in our Video Library, give you an example of the varying levels of energy coming from our WiFi Routers. If I was using the same meter on say, your WiFi, the measurements could vary widely.
This is extremely controversial but we can’t ignore that plenty of animal models indicate that exposure to electromagnetic radiation increases the risk of tumor development. While human studies are rare, reports and case studies abound. One such case involves a young 21-year-old woman who developed breast cancer. What makes this case unique was that her family did not have a predisposition to breast cancer… and she developed the tumor right on the spot she carried her cell phone in her bra. 
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.
On May 31, 2011, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) issued a press release announcing it had added cell phone radiation to its list of physical agents that are "possibly carcinogenic to humans" (group 2B agents).  The classification was made after a working group of 31 scientists completed a review of previously published studies and found "limited evidence of carcinogenicity" from the radiofrequency electromagnetic fields emitted by wireless phones, radio, television, and radar. 
The following is an excerpt of a typical conclusion published in a scientific journal about the links between EMFs, cell phones and health: "Epidemiologic research shows a low degree of association, inconsistency and missing dose-effect relations. A biologic mechanism of action is still debatable. No harm to human health has been shown. Conclusion: There is no scientific basis as to the harmful effects of EMFs on human health."

Members of the public often ask about the cumulative exposure that a child receives when using a Wi-Fi device in a classroom in which a number of children are simultaneously using Wi-Fi. When downloading files, most of the transmissions will be from the access point, not the students’ device. When downloading and uploading only a portion of the maximum capacity of a network would be used even in a classroom filled with children using Wi-Fi. The Wi-Fi network divides RF transmissions among the access points and client devices therefore the individual RF exposure to a child in a classroom that is using a device consists of sequential exposures from all active devices, the majority of which are located at some distance away(15). For the majority of schools (20) the measurements in the current study were conducted in an empty classroom (to avoid lesson disruption) with an access point and one laptop. In three schools, measurements were conducted with students or teachers present and using Wi-Fi devices. A comparison between measurements conducted in empty classrooms and classrooms with multiple students/teachers using Wi-Fi showed no significant difference in the RF levels (p > 0.1 for all); although this may have been due to low numbers (only three schools measured with multiple users in the classroom).
International guidelines on exposure levels to microwave frequency EMFs such as ICNIRP limit the power levels of wireless devices and it is uncommon for wireless devices to exceed the guidelines. These guidelines only take into account thermal effects, as nonthermal effects have not been conclusively demonstrated. The official stance of the British Health Protection Agency is that “[T]here is no consistent evidence to date that WiFi and WLANs adversely affect the health of the general population”, but also that “...it is a sensible precautionary approach...to keep the situation under ongoing review...”.
BACKGROUND: Dental amalgam is composed of approximately 50% elemental mercury. Despite concerns over the toxicity of mercury, amalgam is still the most widely used restorative material. Wi-Fi is a rapidly using local area wireless computer networking technology. To the best of our knowledge, this is the first study that evaluates the effect of exposure to Wi-Fi signals on mercury release from amalgam restorations.
These experimental findings raise new questions as to the potential for radiofrequency radiation to result in cellular changes and offer potential avenues for further laboratory studies. Cancers in the heart are extremely rare in humans, where the primary outcomes of potential concern with respect to radiofrequency radiation exposure from cell phones are tumors in the brain and central nervous system. Schwann cells of the heart in rodents are similar to the kind of cells in humans that give rise to acoustic neuromas (also known as vestibular schwannomas), which some studies have suggested are increased in people who reported the heaviest use of cell phones. The NTP has stated that they will continue to study this exposure in animal models to further advance our understanding of the biological underpinnings of the effects reported above.
Lloyd’s precautions are good ones, although he doesn’t cover cell phone use. I’ve worked on cellular telephony for the last 18 years, coming to the same conclusions about cell phones about ten years ago, the science had gotten conclusive enough for me, as I doubted at first that they could be a problem. As you may have heard, you don’t want to talk on them next to your head if you can help it, use speakerphone mode or wired or Bluetooth headset (BT is very low power, usually keeping itself around only a milliwatt, although wired or speakerphone is better). Don’t park it all day long on any body parts you want to keep cancer-free, especially the pelvic and pectoral regions (trying to keep it classy here). I wouldn’t advise living within a third of a mile of a cell phone tower, or within a mile of a TV tower, if you can help it. Best wishes all.
Add Negative Ions: Exposure to WiFi can result in the build-up of positive ions that can have negative effects on our bodies. We can neutralize this by adding negative ions to our lifestyle, negative ions are highest after a thunderstorm and are present from the energy caused by the crashing waves on the beach. You can also try a negative ion generator.
This investigation concerns with the effect of low intensity microwave (2.45 and 16.5 GHz, SAR 1.0 and 2.01 W/kg, respectively) radiation on developing rat brain when exposed for 35 days. Results showed that the chronic exposure to these radiations caused statistically significant (p<0.001) increase in DNA single strand breaks in brain cells of rat.
“In addition to protecting your phone from scratches and breaks, a basic case can help conceal a distinctive phone’s telltale markings. That’s a detriment if you’re trying to show off your handset’s badass styling, but a benefit for maintaining a lower profile. Note: Even though they look better, a flashy designer case is like sticking a “steal me” marquee on your phone.” – Jessica Dolcourt, Keep Your Phone from Getting Stolen (and What to Do If It Is), CNET; Twitter: @CNET
