Carlo sent letters to each of the industry’s chieftains on October 7, 1999, reiterating that the WTR’s research had found the following: “The risk of rare neuro-epithelial tumors on the outside of the brain was more than doubled…in cell phone users”; there was an apparent “correlation between brain tumors occurring on the right side of the head and the use of the phone on the right side of the head”; and “the ability of radiation from a phone’s antenna to cause functional genetic damage [was] definitely positive….”8

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.
These days it takes more than simply ringing the steel triangle on your deck to round up the kids for supper. Technology has advanced, and the need for a more efficient way to maintain contact with children from afar has only increased, bolstered by their growing thirst for independence and reliance on consumer technology. Despite the fact that cell phones have become the obvious solution for basic communication and contact in lieu of the landline — and to a lesser degree, the steel triangle — they still pose both a financial and safety risk.
Because of this physical law, even if  holding a Wi-Fi router directly against your forehead was very dangerous (and, we assure you, it is not) working in your home office 45 feet away from the Wi-Fi router would not be dangerous simply because the microwave radiation of the already minuscule 1 watt Wi-Fi router would have radically decreased in intensity. When you factor in that the Wi-Fi radiation is already harmless, you see that there is no situation in which the Wi-Fi signal from your router, your laptop, your media center, or any other Wi-Fi device in your home could possibly hurt you.
... our review shows that there is a substantial amount of studies which indicate that plants have experienced physiological or morphological changes due to radiofrequency radiation and show statistically significant changes for the short-term exposure duration (up to 13 weeks). In contrast, the results obtained from the long-term exposure studies (two publications using nine different exposures with exposure duration between 3 months to 6 years) support no physiological effects on plants when exposed to radiofrequency radiation from mobile phone radiation. This would bring a remarkable point to the discussion about the apparent absence of response to the long-term exposure that may be interpreted as adaptations. On the other hand, phenotypic plasticity of plants will permit them to change their structure and function; hence, plants to adapt to environmental change (Nicotra et al., 2010). Plants are naturally affected by environmental stresses due to their immobility. Plants could respond to the environmental factors of wind, rain, electric field and ultraviolet radiation and adjust its physiological condition to adapt to the change of environment (Braam and Davis, 1990; Braam et al., 1996; Mary and Braam, 1997) .... our previous findings (Halgamuge et al., 2015) indicate that the biological effects considerably relied on field strength and amplitude modulation of the applied field.

“It’s because WiFi is just a low frequency sound wave.” For me, the jury is still out concerning the link between WiFi and sleep disturbance. But I’m sorry, you are wrong about WiFi being a low frequency sound wave. It is a radio wave, i.e. electromagnetic, and it runs at 2.3 GHz and/or 5 GHz, which cannot by any stretch of the imagination be described as low frequency.
Two wireless trade associations contributed $4.7 million to the Interphone study launched by the WHO’s International Agency for Cancer Research in 2000. That $4.7 million represented 20 percent of the $24 million budget for the Interphone study, which convened 21 scientists from 13 countries to explore possible links between cell phones and two common types of brain tumor: glioma and meningioma. The money was channeled through a “firewall” mechanism intended to prevent corporate influence on the IACR’s findings, but whether such firewalls work is debatable. “Industry sponsors know [which scientists] receive funding; sponsored scientists know who provides funding,” Dariusz Leszczynski, an adjunct professor of biochemistry at the University of Helsinki, has explained.35
The NTP study was to be peer-reviewed at a meeting on March 26–28, amid signs that the program’s leadership is pivoting to downplay its findings. The NTP had issued a public-health warning when the study’s early results were released in 2016. But when the NTP released essentially the same data in February 2018, John Bucher, the senior scientist who directed the study, announced in a telephone press conference that “I don’t think this is a high-risk situation at all,” partly because the study had exposed the rats and mice to higher levels of radiation than a typical cell-phone user experienced.50

Radiation from cell phones can damage sperm. Cell phone storage in front pockets has been linked to poor fertility and higher chances of miscarriage and childhood cancer. [18] According to the Cleveland Clinic Center for Reproductive Medicine, semen quality "tended to decline as daily cell phone use increased." [19] According to a May-June 2012 meta-study in the Journal of Andrology, "men using mobile phones have decreased sperm concentration" in addition to "decreased viability" of their sperm. [64]


Wi-Fi certainly isn’t going to do you in, but something else you forgot to worry about while you were worrying about your Wi-Fi router might: put that worry to good use and make sure there are fresh batteries in your smoke detectors, that you’re planning on getting a yearly physical this year, and you floss before bed (you know, those things you’ve been putting off that might actually, sooner or later, harm you).


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." [39] A July 27, 2011 study found that there was no association between cell phone use and brain tumor risks among children and adolescents. [50] 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. [1] [41] [42] [45] [46] [49]
Not only are these devices of radically different operating powers, but they are equally at the mercy of the Inverse-square law. The Inverse-square law is a physical law which states that the quantity or intensity of linear-wave radiation is directly inverse to the distance the observing/affected body is from the source of the radiation. In the illustration above, you can see how the further the given area (A) is from the source of the radiation (S), the less exposure it receives. This law applies to radio, microwaves, visible light, and all manner of waves we experience around us in the natural world.

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). [38] 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. [37]
The aim of this study was to investigate long-term effects of 2.4 GHz radiofrequency radiation (24 h/day for 1 year) emitted from a Wireless Fidelity (Wi-Fi) system on the testes of male rats. Results showed that sperm head defects increased in the exposure group (p < 0.05) while weight of the epididymis and seminal vesicles, seminiferous tubules diameter and tunica albuginea thickness were decreased in the exposure group (p < 0.01, p < 0.001, p < 0.0001). However, other alterations of other parameters were not found significant (p > 0.05). We suggest Wi-Fi users to avoid long-term exposure of RF emissions from Wi-Fi equipment.
Of course they’re not. But they are banning wireless communication in nursery schools, because that’s new and parents aren’t entirely sure about what makes it work. Parents are, quite rightly, very worried about how any new thing will affect their children. Some things, like the effect of texting using proper grammar or how more screen time affects attention spans, are difficult to measure and we don’t really know how people will be when they grow up. But Wi-Fi as a cause of cancer or even headaches? We can test for that. We have tested for that. It’s fine.

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.

One of the convenient features of having a smartphone is to quickly access email or social media accounts with just a tap of a finger. However, this also means that you are always connected to accounts that may contain sensitive information. Consider logging out of certain accounts if you can so that others can’t access those accounts if they are using your phone. Keep in mind that depending on the type of phone you have, you might not be able to log out of some accounts, such as email accounts, but may have to remove the entire account from your phone. In this case, make your decision based on your own privacy and safety risk. While it may be inconvenient to access the account through the browser instead, it may be safer.
According to American Academy of Pediatrics President Dr. Robert Block, when cell phones are used by children, "the average RF energy deposition is two times higher in the brain and 10 times higher in the bone marrow of the skull," than for adults. [68] A July 2008 peer-reviewed study shows that children under the age of eight absorb twice the amount of radiation into their brain tissue as adults due to their lower skull thickness. [17]
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.

According to the results of the current research, long-term exposure to EMR emitted from wireless devices had adverse effects on the antioxidant potential of blood. Therefore, to protect individuals from harmful effects of Wi-Fi signals, it is advised to limit the use of such devices for household and occupational activities, if possible. This study may stimulate future helpful research in the development of new protective or therapeutic approaches. In addition, it is recommended that the target tissues of EMR emitted from wireless devices and the level of other mediators be investigated to understand the exact molecular mechanism and site of action upon continuous exposure to such radiations.

The environmental exposure to RF radiation in some schools is higher than reported levels for non-thermal biological effects. In order to reduce children’s exposure to RF radiation, schools should prefer wired network connections, allow laptop, tablets, and mobile phone usage only in flight mode and deactivate Wi-Fi access points when internet is not needed for learning purposes.


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.

This is a 2 pieces of plastic sandwiched together by glue. Don't believe me? Take it apart. This item works no better than the existing case on your phone. If you are that concerned with cellphone radiation, you should be equally concerned about the cheap plastic and toxic glue that this is comprised of. Also know the fact that they've stolen $25 from your wallet when you purchase this hokey product...Technology at it's finest.

Another thing, a WiFi router is not continuously sending data, when devices don’t communicate to the internet. In an idle situation, a WiFi router just sends beacon signal, like “Hello I’m a WiFi router” every x miliseconds and your smartphone just listen to it, like a radio. The same is for GSM/3G/4G. Your mobile is not communicating to the GSM antenna continuously, otherwise it would drain your battery in minutes and your mobile gets very hot. Further more, the government forced the mobile companies to lower the transmit power, that’s why you see more GSM antennas (actually called basestations) in places like cities for better coverage.


George Carlo seemed like a good bet to fulfill Wheeler’s mission. He was an epidemiologist who also had a law degree, and he’d conducted studies for other controversial industries. After a study funded by Dow Corning, Carlo had declared that breast implants posed only minimal health risks. With chemical-industry funding, he had concluded that low levels of dioxin, the chemical behind the Agent Orange scandal, were not dangerous. In 1995, Carlo began directing the industry-financed Wireless Technology Research project (WTR), whose eventual budget of $28.5 million made it the best-funded investigation of cell-phone safety to date.4
This is an animal experimental study, which was conducted in the Department of Anatomical Sciences, Faculty of Medicine, Zanjan University of Medical Sciences, Zanjan, IRAN, from June to August 2014. Three-month-old male Wistar rats (n=27) were exposed to the 2.45 GHz radiation in a chamber with two Wi-Fi antennas on opposite walls. Animals were divided into the three following groups: I. control group (n=9) including healthy animals without any exposure to the antenna, II. 1-hour group (n=9) exposed to the 2.45 GHz Wi-Fi radiation for 1 hour per day during two months and III.7-hour group (n=9) exposed to the 2.45 GHz Wi-Fi radiation for 7 hours per day during 2 months. Sperm parameters, caspase-3 concentrations, histomorphometric changes of testis in addition to the apoptotic indexes were evaluated in the exposed and control animals.
What a dishonest shit article. There is no evidence that Wi-Fi does anything mentioned here. I read one of your “citations” about its link to insomnia and the study you link doesn’t even come close to mentioning WiFi. Your vague “link to cancer” citation is a local news piece. This kind of shit just reinforces people’s pseudoscientific nonsense beliefs.
Our homemade demonstration of all the cases uses a working phone. Not the shielding material by itself, but the actual "shielding" SafeSleeve, Pong, Reach,  Vest, ShieldMe, and Defender Shield cases. First we get RF power density measurements from a phone that's on a call and then, in the same location, within minutes of the first reading, we place the same phone as it's engaged in a call into each case and we take additional reading with the meter.
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?
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.
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.
18. Hang up when necessary. “Just because you can talk in the car doesn’t mean you always should. If you’re getting into a hairy traffic situation or the skies open up with buckets of rain, don’t try to power through it. These hazardous situations require your full attention, so end your call and focus up.” – Taking a Call?
