Foster was Moulder’s coauthor on that 2013 review of Wi-Fi’s health effects. He says that, based on our current understanding of radio wave strengths and risks, world health authorities have set safety standards for all devices and appliances that emit electromagnetic radiation—from phones and microwaves to your car’s keyless entry fob. “The exposure you get from your Wi-Fi router is orders and orders of magnitude below those safety limits,” he explains.
MATERIALS AND METHODS: Adult male Sprague-Dawley rats in the weight range of 230 to 260 g were divided into control, sham, Wi-Fi exposed groups. After long term exposure (4 h/day for 45 days) to Wi-Fi electromagnetic radiation, plasma levels of glucose and insulin during intraperitoneal glucose tolerance test were measured. Islet insulin secretion and content, lipid peroxidation and antioxidant status in pancreas of rats were determined.

It’s worth remembering that Wi-Fi occupies the same part of the spectrum as microwaves, which sounds terribly alarming. If it can boil water, surely it’s bad for us too? Well, no. Not at such low power. This is also the frequency of the cosmic background radiation, the echoes of the big bang that fill the sky. There is literally nowhere in the universe that does not have microwaves pinging around in it.


A study by the Corporate EME Research Laboratory and Motorola Florida Research Laboratories tested 9 different cell phone radiation shields, 5 of which claimed to block 99% of cell phone radiation. The other 4 shields tested claimed to emit a reverse radiation that would cancel out the harmful radiation from cell phones. The study found that all of the radiation shields had no effect on the amount of radiofrequency radiation a cell phone user is exposed to from their phone.[2]

2.	Our products are designed to provide an anti-radiation barrier between the device and the body. This way, the devices are still usable and able to send and receive signal out of the non-shielded side while shielding the EMF away from the body. Because of this, you will only see a reduction in EMF levels on the shielded side of the device. The test you have conducted shows the highest levels from anywhere around the device.

Outside critics soon came to suspect that Carlo would be the front man for an industry whitewash. They cited his dispute with Henry Lai, a professor of biochemistry at the University of Washington, over a study that Lai had conducted examining whether cell-phone radiation could damage DNA. In 1999, Carlo and the WTR’s general counsel sent a letter to the university’s president urging that Lai be fired for his alleged violation of research protocols. Lai accused the WTR of tampering with his experiment’s results. Both Carlo and Lai deny the other’s accusations.5
When you make a call, text, or use data, your phone sends and receives RF signals back and forth between its antenna and nearby cell towers. The radiation from Bluetooth and WiFi devices falls into the same basic range on the electromagnetic spectrum—between FM radios and microwave ovens—as the RF waves from cell phones. But because the distances traveled by WiFi and Bluetooth signals tend to be much shorter (between your router and your laptop, for instance, or your smartphone and your wireless speaker) the RF can be transmitted at a much lower power than from a cell phone, which could reduce the effect it has on living tissue.

The U.S. Food and Drug Administration (FDA) notes that studies reporting biological changes associated with radiofrequency radiation have failed to be replicated and that the majority of human epidemiologic studies have failed to show a relationship between exposure to radiofrequency radiation from cell phones and health problems. The FDA, which originally nominated this exposure for review by the NTP in 1999, issued a statement on the draft NTP reports released in February 2018, saying “based on this current information, we believe the current safety limits for cell phones are acceptable for protecting the public health.” FDA and the Federal Communications Commission share responsibility for regulating cell phone technologies.
Radiation is also the thing that bathes the world in warm sunlight, and makes life on Earth possible. Radiation is also the reason we can turn on a radio and hear music without wires. Radiation is how we change the channels on our television (and for anyone getting their TV fix via over-the-air channels or satellite TV, how the programming gets delivered to their home in the first place).
Electromagnetic fields have been shown to disrupt melatonin production. In turn, sleep and overall health are disrupted. Charge your phone in another room. If you must be available to loved ones during the night, keep a corded phone next to your bed, or keep the cell phone on the other side of the room. (See more about safe sleeping in the post Sleep, Melatonin and Electronic Devices.)

When the Interphone conclusions were released in 2010, industry spokespeople blunted their impact by deploying what experts on lying call “creative truth-telling.” “Interphone’s conclusion of no overall increased risk of brain cancer is consistent with conclusions reached in an already large body of scientific research on this subject,” John Walls, the vice president for public affairs at the CTIA, told reporters. The wiggle word here is “overall”: Since some of the Interphone studies did not find increased brain-cancer rates, stipulating “overall” allowed Walls to ignore those that did. The misleading spin confused enough news organizations that their coverage of the Interphone study was essentially reassuring to the industry’s customers. The Wall Street Journal announced “Cell Phone Study Sends Fuzzy Signal on Cancer Risk,” while the BBC’s headline declared: “No Proof of Mobile Cancer Risk.”37


The study was an attempt to draw attention towards the adverse effects of non-ionizing electromagnetic radiations (NI-EMR) in the frequency that is used widely in the field of telecommunication. Many studies have captured the impact of the 900 MHz and 1800 MHz frequencies, however the frequency of radiation in Wi-Fi range has not been much explored. Along with the use of cell phones there is a growing concern with the use of Wi-Fi devices which continuously emit radiations in the frequency of 2.4 GHz. Hence we thought it prudent to investigate the impact of radiation of the frequency of 2.45 GHz. It can be concluded that the exposure to non-ionizing radiation of 2.45 GHz caused detrimental changes in rat brain leading to learning and memory decline and expression of anxiety behavior along with fall in brain antioxidants. The exposure triggered the gene expression of caspase 3 which plays a major role in the apoptotic pathway. The chronic impact of non-ionizing radiation needs to be thoroughly evaluated in humans so that combative steps can be taken.

Here we studied the influence of microwave irradiation at bands corresponding to wireless router (WLAN) and mobile devices (GSM) on leaf anatomy, essential oil content and volatile emissions in Petroselinum crispum, Apium graveolens and Anethum graveolens. Microwave irradiation resulted in thinner cell walls, smaller chloroplasts and mitochondria, and enhanced emissions of volatile compounds, in particular, monoterpenes and green leaf volatiles. There was a direct relationship between microwave-induced structural and chemical modifications of the three plant species studied. These data collectively demonstrate that human-generated microwave pollution can potentially constitute a stress to the plants.
We’re living in a wireless technology age, but there’s some evidence that exposure to electromagnetic radiation from cell phones and wireless devices could increase your risk of certain cancers and tumors. However, more research is needed. In the meantime, I recommend practicing the precautionary principle. Some great cell phone safety tips include:

The easiest thing for you to do is to put a passcode on your phone. Having a passcode will make it harder for someone to pick up your phone to scroll through, access your accounts, or install something malicious. In the event that your phone gets stolen or you lose it, it’ll make it a bit harder for others to get into your phone. Most phones just ask for a 4-digit passcode, but some phones will allow you to use a more complex passcode.
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.
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.
The agency is finally moving to meet the realities of the 21st century and the Information Age. On June 15, FCC chairman Julius Genachowski circulated a proposal to his four fellow commissioners calling for formal review of the 1996 regulations. To advance, his plan must be approved by a majority of the commissioners. If they agree, the FCC could take the long overdue step of modernizing its safety standards. But the pace is likely to be glacial.
Critics also attacked what they regarded as the slow pace of WTR research. The WTR was merely “a confidence game” designed to placate the public but stall real research, according to Louis Slesin, editor of the trade publication Microwave News. “By dangling a huge amount of money in front of the cash-starved [scientific] community,” Slesin argued, “Carlo guaranteed silent obedience. Anyone who dared complain risked being cut off from his millions.” Carlo denies the allegation.6
Our studies point that WIFI is not completely safe at home near the animal or human body because it employ harmful radio waves. But it is safer compared to cellphone that it is close to our brain during communications. WIFI signals are everywhere. If you switched off your WiFi at night, you are still exposed to the WIFI signals coming in from neighbors but we have a significant reduction of the bioeffects of WIFI with distance from the router. Future investigations will focus on the long term bioeffects of WIFI placed at an important distance from the animal or the human.
The key factor when selecting a cell phone case is making sure that you choose the exact one your phone needs. Cases are specific to not only brands of cell phone, but specific models as well. For example, if you have version three of a cell phone model, it may not fit a version six, and vice versa. Make sure that you know exactly what case you need. The cases protect the corners and back of the phone, and a clear tempered glass or Plexiglas shield protects the face. This glass or film is usually scratch- and smudge-resistant, and the cases are rubber or polycarbonate. Some cases have clips on the back that allow you to connect the phone to a belt or bag. Many cases are black, but multiple colors and patterns are available too.
The present work investigated the effects of prenatal exposure to radiofrequency waves of conventional WiFi devices on postnatal development and behavior of rat offspring. Ten Wistar albino pregnant rats were randomly assigned to two groups (n=5). The experimental group was exposed to a 2.45GHz WiFi signal for 2h a day throughout gestation period. Control females were subjected to the same conditions as treated group without applying WiFi radiations. After delivery, the offspring was tested for physical and neurodevelopment during its 17 postnatal days (PND), then for anxiety (PND 28) and motricity (PND 40-43), as well as for cerebral oxidative stress response and cholinesterase activity in brain and serum (PND 28 and 43). Our main results showed that the in-utero WiFi exposure impaired offspring neurodevelopment during the first seventeen postnatal days without altering emotional and motor behavior at adult age. Besides, prenatal WiFi exposure induced cerebral oxidative stress imbalance (increase in malondialdehyde level (MDA) and hydrogen peroxide (H2O2) levels and decrease in catalase (CAT) and superoxide dismutase (SOD) activities) at 28 but not 43days old, also the exposure affected acethylcolinesterase activity at both cerebral and seric levels. Thus, the current study revealed that maternal exposure to WiFi radiofrequencies led to various adverse neurological effects in the offspring by affecting neurodevelopment, cerebral stress equilibrium and cholinesterase activity.
Belgium recently adopted new cell phone regulations that bar mobile phone models designed for, and marketed to children ages 7 and younger.  Under Belgium’s new rules, slated to take effect next March, cell phone retailers will be required to disclose phones’ maximum emission levels, known as specific absorption rates, or SAR, at the point of sale.  Belgium becomes the latest in a rapidly lengthening list of nations to attempt to shield children from too much cell phone radiation and to inform everyone about the risks of exposure to these emissions. At least a dozen other nations have taken steps to protect children from cell phone radiation.

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. 
It is useful to be aware of new health research regarding cell phone usage and cell phone radiation. The first cell phone call was made in 1985 and that phone cost $5,000 and weighed about 9 pounds. The change in size, weight and cost of devices today has probably led to over 50% of the human race owning a mobile device, the fastest growing technology on the planet.
