Exposure to non-thermal radio frequency radiation from Wi-Fi and cellular phones can disrupt normal cellular development, especially fetal development. A 2004 animal study linked exposure to delayed kidney development. [4] These findings were supported by a 2009 Austrian study. In fact, the disruption of protein synthesis is so severe that authors specifically noted, “this cell property is especially pronounced in growing tissues, that is, in children and youth. Consequently, these population groups would be more susceptible than average to the described effects.” [5] In short, bathing the developmentally young in Wi-Fi increases their risk of developmental issues.
In one type of study, called a case–control study, cell phone use is compared between people with these types of tumors and people without them. In another type of study, called a cohort study, a large group of people who do not have cancer at study entry is followed over time and the rate of these tumors in people who did and didn’t use cell phones is compared. Cancer incidence data can also be analyzed over time to see if the rates of brain tumors changed in large populations during the time that cell phone use increased dramatically. These studies have not shown clear evidence of a relationship between cell phone use and cancer. However, researchers have reported some statistically significant associations for certain subgroups of people.
The present study investigated the influence of 2.4GHz electromagnetic fields, similar to that emitted by Wi-Fi system, on human brain activity. The presence of radiation had no effect on the energies of alpha and beta band of male subjects, while it reduced these energies of female subjects, resulting in significantly lower energies, as compared to those of males. Delta and theta band energies did not experience any noteworthy effect from gender, radiation condition and their interaction. Conversely, there was a significant interaction effect (gender x radiation) on the energies of alpha and beta rhythms. The present data support the idea that Wi-Fi signal may influence normal physiology through changes in gender related cortical excitability, as reflected by alpha and beta EEG frequencies.

Cell phone cases can make matters worse because they may block the phone’s antenna. The device must work harder to transmit signals which may lead to  more radiation exposure for the user. (See safety tip #6 for more on the importance of a strong signal.)  Certification testing done by phone manufacturers are done with bare phones with no accessories.
You can search for the most popular cell phone cases and covers, browse cases and covers by brand, and even refine your search by need. Cell phone cases provide a variety of protection. Some people put a large emphasis on military-grade protection, to ensure that all angles of their case are secure, no matter the terrain. Others may desire cases that give easy access to headphone ports or charging outlets, to have access to home speakers or audio cables. The engineering of cases can become even more specific—right down to the beveled edges that raise your screen protectively above a flat surface or the grip finish smoothly designed onto the back of your phone to ensure maximum ease in typing. Whatever your need, Amazon is sure to carry the brand, features, and colors you care about. Check the Deals page regularly to even see some of your favorite cases on discount. Amazon is sure to carry the widest selection of cases; you just worry about carrying yours.

While cell phones localize the highest microwave exposure to the brain, Wi-Fi  exposures are often localized to the abdomen, leg and chest area. However this is not always the case as some people sleep in rooms with Wi-Fi baby monitors, Wi-Fi routers or Wi-Fi gaming devices near their pillow. Wi-Fi printers may be in offices next to a person’s desk and most people are unaware that they transmit continuously. All in all, for some people- especially children- the Wi-Fi exposure is quite significant to overall cumulative exposure.

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
So I am not surprised at all then today to find this article, which just confirms what my body was very clearly telling me already. I am only surprised that more people don’t feel the effects of this kind of radiation in their body, and bother to argue about it. If our whole society (especially western countries) had not become so desensitized, and out of touch with their bodies, there would not be any controversy or discussion about it, anyone could just feel the effects of radiation… and would act accordingly.

In this study, the effect of Wi-Fi radiation exposure as a threat to brain health was studied using genomic analysis and histopathological study which showed the high risk of its genotoxicity especially in prolonged exposure spectrum through the findings from this study. The genomic analysis confirmed DNA damage due to Wi-Fi radiation toxicity and DNA damage effect which was seen through the RAPD profiles of animals from the exposed groups. The histopathological analyses also confirmed significant deleterious alterations in the brain tissues of Wi-Fi-exposed animals. Hence, the need to exhibit caution in handling smart devices that are used from day to day is fast becoming a threat to human health and wellness.

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.

DefenderShield Cellphone Radiation Case also claims independent testing and says in their website: That a "sophisticated layering of separate non-toxic, human safe materials processed for maximum radiation blocking efficiency. Each material has unique and targeted radiation-shielding characteristics designed to work in unison to eliminate all radiation emissions from 0 to 10 GHZ and Defender Shield technology refracts, conducts and finally absorbs all these potentially harmful emissions."  In this demonstration, the radiation level measured when DefendeShield case was on is still quite a bit above the level of exposure that I would recommend. I personally do not recommend-holding a phone with a shielding case to your head as the DefenderShield website shows a young woman doing as she demonstrates the product. 
The only consistently recognized biological effect of radiofrequency radiation in humans is heating. The ability of microwave ovens to heat food is one example of this effect of radiofrequency radiation. Radiofrequency exposure from cell phone use does cause heating to the area of the body where a cell phone or other device is held (e.g., the ear and head). However, it is not sufficient to measurably increase body temperature. There are no other clearly established effects on the human body from radiofrequency radiation.

Have you ever felt more awake after using Wi-Fi or even struggled to sleep through the night? Reports of these phenomena have been frequent and even prompted a study in 2007 that evaluated low-frequency modulation from cell phones and its impact on sleep. Participants were exposed to the electromagnetic signals from real phones or no signal from fake phones. Those exposed to the electromagnetic radiation had a significantly more difficult time falling asleep and changes in brainwave patterns were observed. [2]

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.
The present study was designed to determine the possible protective effects of melatonin on oxidative stress-dependent testis injury induced by 2.45-GHz electromagnetic radiation exposure (60 min/day for 30 days). Lipid peroxidation levels were shown to be higher in melatonin-supplemented group compared to EMR only and controls, as well as reduced glutathione and glutathione peroxidase levels. Vitamin A and E concentrations decreased in exposure group, and melatonin prevented the decrease in vitamin E levels. In conclusion, wireless (2.45 GHz) EMR caused oxidative damage in testis by increasing the levels of lipid peroxidation and decreasing in vitamin A and E levels. Melatonin supplementation prevented oxidative damage induced by EMR and also supported the antioxidant redox system in the testis.
All values were far below International Commission on Non-Ionizing Radiation Protection’s (ICNIRP) reference values, but most mean levels measured were above the precautionary target level of 3–6 µW/m2 as proposed by the Bioinitiative Report ….however the ICNIRP guidelines are based on short-term heating (thermal) effects, and are therefore not relevant to decide on the appropriateness of long-term exposure.

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


For those thinking that wireless keyboards and mice are OK, these things can put out quite a significant signal and some at frequencies of 2.4 GHz. I have personally experienced terrible symptoms from one of these. The 27MHz analog transmitters are more benign but probably still significant for the electrosensitive, and can probably still harm anyone.
49. Get insurance on your child’s phone. “54% of kids plan on spending their summer playing outside. With so many opportunities for their cellphone to become broken, stolen or misplaced, it’s important to protect their device with mobile protection, considering that nearly 30% of parents have had to replace a child’s cellphone in the past 18 months. This will protect their device against damage (including water damage), loss and theft. Ask your carrier about getting the most comprehensive coverage available for your device.” – 5 Summer Cellphone Safety Tips for Kids, Asurion; Twitter: @Asurion

The aim of this study was to investigate electromagnetic radiation (EMR) transmitted by wireless devices (2.45 GHz, 3h/day for 30 days), which may cause physiopathological or ultrastructural changes, in the testes of rats and address if the supplemental gallic acid (GA) may reduce these adverse effects. EMR only group was shown to have higher oxidative stress, decreased testosterone and VEGF levels, increased prostaglandin E2 and CGRP, as well as decreased numbers of spermatozoa. Long term EMR exposure resulted in testicular physiopathology via oxidative damage and inflammation. GA may have ameliorative effects on the prepubertal rat testes physiopathology.


In my home and work environment I long ago made the decision to completely steer clear of WiFi. You might not feel you want to go “the whole nine yards” on this. Here are some ways you can reduce the burden of radio frequency radiation from WiFi on your body. You can pick and choose from this list according to how much you want to reduce WiFi radiation exposure in your life.

Since the development of communication devices and expansion of their applications, there have been concerns about their harmful health effects. The main aim of this study was to investigate laptop thermal effects caused by exposure to electromagnetic fields and thermal sources simultaneously; propose a nondestructive, replicable process that is less expensive than clinical measurements; and to study the effects of positioning any new device near the human body in steady state conditions to ensure safety by U.S. and European standard thresholds. A computer simulation was designed to obtain laptop heat flux from SolidWorks flow simulation. Increase in body temperature due to heat flux was calculated, and antenna radiation was calculated using Computer Simulation Technology (CST) Microwave Studio software. Steady state temperature and specific absorption rate (SAR) distribution in user's body, and heat flux beneath the laptop, were obtained from simulations. The laptop in its high performance mode caused 420 (W/m2 ) peak two-dimensional heat flux beneath it. The cumulative effect of laptop in high performance mode and 1 W antenna radiation resulted in temperatures of 42.9, 38.1, and 37.2 °C in lap skin, scrotum, and testis, that is, 5.6, 2.1, and 1.4 °C increase in temperature, respectively. Also, 1 W antenna radiation caused 0.37 × 10-3 and 0.13 × 10-1.
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
“The absence of absolute proof does not mean the absence of risk,” Annie Sasco, the former director of epidemiology for cancer prevention at France’s National Institute of Health and Medical Research, told the attendees of the 2012 Childhood Cancer conference. “The younger one starts using cell phones, the higher the risk,” Sasco continued, urging a public-education effort to inform parents, politicians, and the press about children’s exceptional susceptibility.28
There is a catch, though: The Internet of Things will require augmenting today’s 4G technology with 5G, thus “massively increasing” the general population’s exposure to radiation, according to a petition signed by 236 scientists worldwide who have published more than 2,000 peer-reviewed studies and represent “a significant portion of the credentialed scientists in the radiation research field,” according to Joel Moskowitz, the director of the Center for Family and Community Health at the University of California, Berkeley, who helped circulate the petition. Nevertheless, like cell phones, 5G technology is on the verge of being introduced without pre-market safety testing.26
The presented data collectively suggest that microwave irradiation constitute a stress to the plants, resulting in enhanced emissions of GLV, up-regulation of terpenoid emissions and modification in essential oil content and foliage anatomy. Anatomical and emission traits suggested that WLAN-frequency irradiation resulted in more severe stress than GSM-frequency irradiation, but the effect of WLAN-frequency irradiation on essential oil was inhibitory. There was an agreement between anatomical and chemical traits with anatomically most resistant species Apium graveolens being chemically least responsive.
SAR stands for specific absorption rate, a measure of the amount of radio frequency energy absorbed by the body when using a mobile phone. The SAR rating of your cell phone can be found in your instruction manual or possibly online at this Federal Communications Commission website. In the United States, the SAR cannot exceed 1.6 watts per kilogram.

There is only one legitimate method of measuring cell phone radiation recognized by every major health authority and government in the world as well as by the cell phone industry itself, referred to as "SAR". SAR testing measures the "Specific Absorption Rate" of radiation at multiple depths and locations on the head and body in order to quantify how much radiation is actually penetrating it with and without certain safety devices. You can see a SAR test of the R2L device by watching the video below.
Bluetooth allows your phone to communicate with other devices, such as the hands-free option in your car or your printer. If accessed by someone else though, they could misuse it to access your information or intercept your calls. Turn off the Bluetooth on your phone and turn it on only when you need to connect with other device. Many phones also allow users to set passcodes or additional security levels on their Bluetooth as well. Use all available options to increase your privacy.
The iPad case is made of real leather, a natural and organic material, and allows you or your children to use an iPad safely, without having to worry about radiation pouring from the pad as you read, write, watch TV's or movies, or play your favorite games. It contains all the necessary heat and radiation shielding to keep you safe from iPad radiation, including protection from:
We can’t stop people from misleading others for profit, but we can respond to their nonsense. We’ve received more than a few letters here at How-To Geek from concerned readers asking if they should turn off their wireless equipment when not in use, or get rid of it altogether. So we’ve decided to add a reasonable voice to the conversation so, hopefully, people will find this and breathe a much deserved sigh of relief.

I have just received my wifi connection home first time In my life and I can tell you it has not been a pleasant experience since installation. In the beginning my wifi router was emitting horrible smell that made me feel sick and I also experienced some kind of invasion on my body and head I did not know how to call it until the technician described it for me as being radiations. At night my brain was suffering noise and my vision freckles like that of after tv trasmission would end in the past. I do not mean to be funny but this is the best way I can describe it. And the previously described is also combined with noise in the ears. Now the smell is a bit less but it is still there. I am able to sleep but with all that noise in my head. I also suffered feeling as if very tired although I do not know if it was all due to the wifi. After that I am busy looking for safer internet connection but have not found any yet especially after I read about the hazards.

The present study examined the biological effects of  continuous wave 2.45 GHz microwave radiation (2h/day for 30 days)  in Parkes strain mice. The results show that microwave radiation caused an increase in erythrocyte and leukocyte counts, a significant DNA strand break in brain cells and the loss of spatial memory in mice. This report for the first time provides experimental evidence that continuous exposure to low intensity microwave radiation may have an adverse effect on the brain function by altering circadian system and rate of DNA damage.


“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.
