The use of Wi-fi has increased rapidly in recent years. Through the use of this technology, electronic devices are connected to a computer network wirelessly using radio waves, or radiofrequency (RF) electromagnetic energy (EME), thereby eliminating or reducing the need for network cables. A common example is a laptop connected to the internet using a wi-fi modem at home. Wi-fi access points can also be found in schools and many public areas. People in a wi-fi enabled environment will be exposed to low level RF EME from time to time when using the network on computers and also from the access points. There is some public concern about potential health effects associated with RF EME emissions from wi-fi in homes, schools and other places.
Asked for specifics, Foster says it helps to understand how Wi-Fi works. While most people assume their wireless router is constantly sending and receiving information, Foster says these devices actually transmit just 0.1% of the time. “Maybe that goes up somewhat if you’re streaming video,” he says, “but most of the time your router is just sitting idly waiting for something to happen.”
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.
Several studies that will provide more information are under way. Researchers from the Centre for Research in Environmental Epidemiology in Spain are conducting another international case–control study—Mobi-Kids—that will include 2000 young people (aged 10–24 years) with newly diagnosed brain tumors and 4000 healthy young people. The goal of the study is to learn more about risk factors for childhood brain tumors.
Even though a phone is a great way for parents to maintain contact with their children, picking the right one isn’t always easy. Parents must address crucial factors, such as cost and control, while simultaneously appeasing their children with features such as games, apps, photos, and texting, among other things. Here are our top picks for the best smartphones and cell phones for kids, so you can keep in contact with your loved ones at all times (even if they don’t want you to). Consider pairing your chosen phone with one of the best parental control apps or, if you opt for an Android device, take a look at Google’s Family Link for more peace of mind.
The HARApad laptop pad is available in 3 sizes and multiple colors. There's even an attractive wood option, which allows for a beautiful, natural approach to laptop radiation shielding. There are size options for 13″, 15″ and 17″ laptops, and even a 25″ LapDesk version that will allow for the convenient use of a mouse, if you use a mouse instead of a trackpad.
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. The typical background power of electromagnetic fields in the home can vary from zero to 5 milliwatts per meter squared. Long-term effects of these electromagnetic fields on human and animal health are still unknown.
you really are stuck with “electricity”. How much electricity do gamma rays produce in human body yet so damaging to human and animal tissues because of their high level of energy. it seems any discussion with you is a waste of time considering your demonstrably shaky fundamentals of physics. you appear to be a very good technician rather than physicist of any kind.

The aim of this study was to investigate the possible protective role of melatonin on oxidative stress induced by Wi-Fi (2.45 GHz, 60min/day for 28 days) EMR in laryngotracheal mucosa of rat. In comparison to control and sham groups, RFR-exposed animals had higher lipid peroxidation levels and lower glutathione peroxidase levels, while the RFR-exposed animals treated with melatonin had significantly lower lipid peroxidation levels and increased glutathione peroxidase activity compared with controls. Results show that there is an apparent protective effect of melatonin on the Wi-Fi-induced oxidative stress in the laryngotracheal mucosa of rats by inhibition of free radical formation and support of the glutathione peroxidase antioxidant system.
Due to the relatively recent adoption of cell phones, the long-term safety of the technology cannot be determined conclusively and caution is warranted. Research on glioma brain tumors shows the average latency period is 20-30 years.  Although cell phones were introduced in 1983, it was not until 2003 that over 50% of the US population had a wireless subscription, so the 20 year mark for mass cell phone use has not yet been reached.   The May 17, 2010 INTERPHONE study, the largest study ever to examine possible links between cell phones and brain tumors, concluded that overall there was "no increase in risk" for glioma or meningioma brain tumors,  but the average user in the study had less than eight years of cell phone exposure.  In his review of the INTERPHONE study results, Dr. Rodolfo Saracci stated that "none of today’s established carcinogens, including tobacco, could have been firmly identified as increasing risk in the first 10 years or so since first exposure." 
There is great variability in survival by brain tumor subtype, and by age at diagnosis. Overall, the 5-year relative survival for brain cancers diagnosed from 2008 through 2014 was 33.2% (49). This is the percentage of people diagnosed with brain cancer who will still be alive 5 years after diagnosis compared with the survival of a person of the same age and sex who does not have cancer.
Like cell phones, routers use radio frequency (RF) energy—a form of electromagnetic radiation—to bring wireless internet to your computer, TV, and other devices. Bluetooth headphones and speakers also rely on RF signals to play music. Smartwatches use RF to connect to your phone. And any WiFi-connected smart devices in your home also receive and transmit data using this type of energy. Do you need to worry about any of that?
When it comes to cell phones, scientists have looked at findings from animal research and cells in test tubes exposed to RF radiation in a lab, as well as observational studies in humans. These human studies have tried to see whether heavy users of cell phones have higher rates of brain cancers and other health problems compared with people who use cell phones less often.
Since we have this subconscious, ever-present fear of death, we employ magical thinking to give us a false sense of power over it. When we create artificial threats to our survival in our imagination, and then avoid practicing behaviors that make us vulnerable to those threats, we feel we have some power over whether we live or die. These are also known as superstitions.
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.
Consider parental-control tools. There are actually two major types of parental controls. The first is family rules or guidelines that you establish with your children, and the second is technology tools provided by cellphone companies, smartphone makers and app developers. If you do use technology to monitor or limit your child’s phone activities, in most cases it’s a good idea to be up front with them and revisit it every now and then as they mature.
“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
I thought I was getting Alzheimers until I read this study. I also had insomnia. I couldn’t focus, concentrate or remember anything. My energy levels were tanked. I felt like I was turning into a vegetable. I was ready to leave the planet, I was getting So depressed… I immediately disabled the wifi and put 2 laptops on an ether net and EVERY SINGLE SYMPTOM CLEARED UP!!!
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.
42. Limit your child’s time on the phone. There’s much discussion about how much screen time is good for kids and teens today, and today’s wireless devices provide access to all the games, chatting features, web browsers, media, and apps they could possibly consume in a lifetime. Setting clear limits on smartphone usage will help you keep screen time within reasonable limits. “Half an hour of screen time is recommended for children 4-5 years old; an hour for ages 5-10; and two hours for high school aged kids.” – Melanie Medina, Growing up Digital – Cell Phone Safety for Kids, Identity Force; Twitter: @IdentityForce
If you’re a family that typically opts for Apple devices, you can share your iTunes content and easily keep track of your child’s location. It certainly isn’t the cheapest smartphone you could buy for your child, but it has great specs, terrific software, and it’s a manageable size for smaller hands. If mom and dad have iPhones already, it’s definitely the most convenient choice. Check out our full review for more information.
According to a peer-reviewed Dec. 2006 study of 420,095 cell phone users in Denmark, the results showed a "reduced brain tumor risk" among long-term subscribers.  Two other peer-reviewed studies also found that cell phone users had a slightly decreased risk of developing brain tumors. A July 20, 2005 Danish study  found a "decreased risk for high-grade glioma," a malignant brain tumor, and a 2005 Swedish study  also found a "decreased odds ratio" for developing glioma as well as meningioma, another type of brain tumor.
In response, we would state that all wireless frequencies currently used by the public are categorized as radiofrequency radiation. People have not been using Wi-Fi for as long as they have been using cell phones, so the research that has looked at long term use of cell phones is very important in considering the long term health risks from wireless and Wi-Fi specifically.
In the years to come, the WTR’s cautionary findings would be replicated by numerous other scientists in the United States and around the world, leading the World Health Organization in 2011 to classify cell-phone radiation as a “possible” human carcinogen and the governments of Great Britain, France, and Israel to issue strong warnings on cell-phone use by children. But as the taxi carried Carlo to Louis Armstrong International Airport, the scientist wondered whether his relationship with the industry might have turned out differently if cell phones had been safety-tested before being allowed onto the consumer market, before profit took precedence over science. But it was too late: Wheeler and his fellow executives had made it clear, Carlo told The Nation, that “they would do what they had to do to protect their industry, but they were not of a mind to protect consumers or public health.”14
This review presents the findings of more than 100 studies that were published in reputable scientific journals. Most of these studies confirm potential health impacts as were summarized in the joint "Nicosia Declaration on Electromagnetic and Radiofrequency Radiation" by the Cyprus and Austrian medical associations in 2017: “Potential health impacts of non-ionizing radiation from EMF/RF (electromagnetic fields/radiofrequencies) of 30 KHz – 300 GHz include carcinogenicity (Class B, IARC 2011), developmental neurotoxicity, effects on DNA, fertility, hypersensitivity and other serious effects are well documented in peer reviewed studies. RFR can increase oxidative stress in cells and lead to increase of pro-inflammatory cytokines and lower capacity to repair DNA single- and double-strand breaks. Cognitive impairments in learning and memory have also been shown. These effects can occur at levels well below existing limits of ICNIRP. ... Exposure to EMF/RF at an early developmental stage is of particular concern due, amongst other, to greater absorption and potential effects on the developing developing brain, nervous system as well as their reproductive system, may induce cancer, cognitive effects, etc.” (www.diagnose-funk.org/publikationen/artikel/detail&newsid=1242 and www.cyprus-child-environment.org/easyconsole.cfm/id/428).
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
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.
In September 2014, Californian oncologists reported four similar case histories of young women who had developed breast cancer in precisely the areas where they normally carried their smartphones. What shocked the doctors was that these women were aged 21 to 39 and had no family history or other risk factors relating to cancer. All their cancers “had striking similarity, all tumours were hormone positive… (with) an extensive intraductal component and… near-identical morphology.” (CaseRepMed., 2013).
