Prenatal exposure to radiation from cell phones may increase the risk of ADHD and other behavior problems in children. According to a peer-reviewed Nov. 2008 study in the journal Epidemiology, exposure to cell phone radiation while in the womb "was associated with behavior difficulties such as emotional and hyperactivity problems around the age of school entry."  A Dec. 2010 study replicated those findings.  A peer-reviewed Mar. 15, 2012 study found that mice exposed to cell phone radiation in the womb "were hyperactive and had impaired memory" as adults. 
Studies have shown an association between cell phone use and a decreased risk of certain brain tumors. 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.
Many modems provided by internet service providers are also routers pushing wifi. So even if you bought your own router and use it for your internet, you’re modem may also be pushing wifi into your home. I just ran into this personally. I was helping my mother in law set up internet in her new home. She had a router that she wanted me to set up, but when doing so I found out the modem her internet company gave her was already pushing out a wifi. Obviously, I disabled that and set up a few ethernet cables in her home.
We aimed to investigate the effects of Wi-Fi-induced EMR on the brain and liver antioxidant redox systems in the rat during pregnancy and development. Sixteen pregnant rats and their 48 newborns were equally divided into control and EMR groups. The EMR groups were exposed to 2.45GHz EMR (1hour/day for 5 days/week) from pregnancy to 3 weeks of age. Brain cortex and liver samples were taken from the newborns between the first and third weeks.
No scientist can say with certainty how many wireless-technology users are likely to contract cancer, but that is precisely the point: We simply don’t know. Nevertheless, we are proceeding as if we do know the risk, and that the risk is vanishingly small. Meanwhile, more and more people around the world, including countless children and adolescents, are getting addicted to cell phones every day, and the shift to radiation-heavy 5G technology is regarded as a fait accompli. Which is just how Big Wireless likes it.55
Consumers need -- now more than ever -- real-world, relevant data on how much radiation their phones emit under various circumstances. The FCC does not require the cell phone industry to disclose these data. One important study showing that certain networks could expose consumers to 30 to 300 times more radiation than other networks was hidden from the public until the information was dated to the point of irrelevancy.
There is no clearly-defined safe distance as this new issue has yet been studied enough. While EMF emissions from different routers vary, for most home WiFi routers, a distance of 40 feet (ideally, or 10 feet at a minimum) will help your body and shouldn’t impact your WiFi connection too much. And beware that radiation from WiFi routers can pass through the walls in your home so keep this in mind as you evaluate the safety of your bed's location. Those who are sensitive to EMFs should take extra efforts to reduce EMFs and chronic proximity to the sources.
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.
Although mainstream outlets may ignore the proven dangers, especially in the US and Canada, researchers have identified several methods that can offer a level of defense. First off, reduced melatonin seems to correspond with exposure. Thus, increasing melatonin through supplementation may help offset some of the effects.    In animal tests, L-Carnitine provides antioxidant support for nutrients negatively affected by 2.4 GHz radiation.  
WiFi operates in the 2 to 5 GHz range -- part of the microwave portion of the electromagnetic spectrum. This is in the same part of the spectrum where cell phones operate so I may refer to WiFi or cellphone electromagnetic radiation interchangeably. These are radio waves -- no different from those used to broadcast television programs, except that they are higher in frequency. They aren't nearly as high a frequency as visible light, and no one worries about getting cancer from visible light (ultraviolet light, on the other hand, causes skin cancer, but this is the minimum energy necessary to cause ionizations that can cause breaks in strands of DNA, which is the mechanism by which cancer cells can be created). There is no credible evidence that non-ionizing radiation has any adverse health effects at all. There is no radiobiologic mechanism that could explain such an association -- and absolutely no scientifically valid evidence that this has ever happened.
In June of 2008, a Japanese study, published in the British Journal of Cancer, considered how mobile phone radiation levels affected different parts of the brain. After studying the mobile phone use of 322 brain cancer patients and 683 healthy adults, the study concluded that using a mobile phone "regularly" did not increase the risk of brain cancer.
SafeSleeve Anti Radiation Case: Safe Sleeve website says they integrate FCC accredited independent lab tested "shielding technology" in their products. There are many links to "SafeSleeve, Is it a Scam?" and "Does SafeSleeve work?" online, but if you follow those links you'll find they go to the actual SafeSleeve site where the question of SafeSleeve protection is addressed. You'll see in this demonstration that the radiation level was higher with the SafeSleeve Case on.
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.
MATERIALS AND METHODS: The study was carried out on 16 Wistar Albino adult male rats by dividing them into two groups such as sham (n = 8) and exposure (n = 8). Rats in the exposure group were exposed to 2.4 GHz radiofrequency (RF) radiation for 24 hours a day for 12 months (one year). The same procedure was applied to the rats in the sham group except the Wi-Fi system was turned off. Immediately after the last exposure, rats were sacrificed and their brains were removed. miR-9-5p, miR-29a-3p, miR-106b-5p, miR-107, miR-125a-3p in brain were investigated in detail.
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.
Cell phones emit radiofrequency (RF) radiation, and RF radiation has been shown to damage DNA and cause cancer in laboratory animals. A peer-reviewed Jan. 2012 study in the Journal of Neuro-Oncology concluded that RF radiation "may damage DNA and change gene expression in brain cells" in mice.  An Aug. 2009 meta-study found that RF radiation "can alter the genetic material of exposed cells."  A 2004 European Union-funded study also found that cell phone radiation can damage genes.  On May 26, 2016, the US National Toxicology Program (NTP) released the first results of its study on cell phone radiation, finding an increased incidence of malignant tumors of the brain (gliomas) and heart tumors (schwannomas) in rats exposed to RF radiation.  The NTP researchers also found DNA damage in the rats exposed to the highest levels of RF radiation.  On Nov. 1, 2018, the NTP released its final peer-reviewed report, concluding that there is "clear evidence of carcinogenic activity” in male rats exposed to RF radiation. 
We couldn't find one legit EMF expert online or anywhere else that would recommend a radiation blocking case or anti-radiation case. Not the Environmental Health Trust or Magda Havas, or Joel Moskowitz, in fact his site, safeEMR cautions against scams and claims for radiation protection. So if a so-called "EMF expert" is recommending any kind of anti-radiation case, they probably aren't that much of an expert.
Based on our results, it can be concluded that the bacterial strains used in this study respond differently to EMFs. These bacteria were capable of responding to environmental stresses that act by activating some specific systems such as ion channels, change via the membrane, DNA repair system, and probably ion efflux pumps in the membrane as well as interactions of molecules and antibacterial agents. There are some ambiguities that need further investigations regarding answering questions such as which cellular mechanism is responsible for adaptation? Which factors are involved in alterations of antibacterial sensitivity? And subsequently, what are the differences in the response to radiation in gram-negative and gram-positive bacteria? Moreover, experiments on different bacterial strains with various electromagnetic fields should be performed in the future to better clarify these uncertainties.
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.  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.”  In short, bathing the developmentally young in Wi-Fi increases their risk of developmental issues.
That may be true today. But some experts have grave concerns about the types of low-intensity radiation our wireless devices produce. “We have animal studies suggesting even low-level exposures to the kind of radio wave radiation associated with Wi-Fi could have a variety of negative health effects,” says Joel Moskowitz, director of the Center for Family and Community Health at the University of California, Berkeley. (Moskowitz has collected much of that research here.)
This experiment investigated the effects of 2.45 GHz microwave radiation exposure (2h/day for 35 days) on the developing rat brain.The study revealed a statistically significant (p < 0.05) decrease in protein kinase C activity in hippocampus as compared to the remaining portion of the whole brain and the control group, while a similar experiment conducted on hippocampus and the whole brain gave a similar result. Electron microscopic study shows an increase in the glial cell population in the exposed group as compared to the control group. This present study is indicative of a significant change after exposure to the above-mentioned field intensity, which suggests that chronic exposures may affect brain growth and development.
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.
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.  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. 
Thank you for this information. I will be looking in to all of this. We have shut off our wifi and have hardwired our house. A cell tower was put in to our neighborhood .08 mile away 5 years ago and we’re just now looking in to the implications of living so close to one. We have a 3 1/2 year old and a 9 month old. My 3 1/2 year old is always complaining of her eyes hurting or a headache. I’m thinking it’s time to sell and move. Thank you again! I appreciate you getting back with me.

Cell phone radiation may disrupt the functioning of pacemakers. A 2005 study in the International Journal of Cardiology found that mobile phones may have "adverse effects" on pacemaker functions under certain conditions.  According to the US Food and Drug Administration (FDA), radiofrequency energy from cell phones can create electromagnetic interference (EMI) that may disrupt the functioning of pacemakers, especially if the cell phone is placed close to the heart.  The American Heart Association includes cell phones on its list of "devices that may interfere with pacemakers." 
The wireless industry’s determination to bring about the Internet of Things, despite the massive increase in radiation exposure this would unleash, raises the stakes exponentially. Because 5G radiation can only travel short distances, antennas roughly the size of a pizza box will have to be installed approximately every 250 feet to ensure connectivity. “Industry is going to need hundreds of thousands, maybe millions, of new antenna sites in the United States alone,” said Moskowitz, the UC Berkeley researcher. “So people will be bathed in a smog of radiation 24/7.”53

Microwave irradiation resulted in thinner cell walls, smaller chloroplasts and mitochondria, and enhanced emissions of volatile compounds, in particular, monoterpenes and green leaf volatiles (GLV). These effects were stronger for WLAN-frequency microwaves. Essential oil content was enhanced by GSM-frequency microwaves, but the effect of WLAN-frequency microwaves was inhibitory. There was a direct relationship between microwave-induced structural and chemical modifications of the three plant species studied.
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
The word radiation is, to the lay person, a scary word. Radiation is the stuff that 1960s school children were taught to climb under their desks to avoid, and what prompted Cold-War-terrified Americans to build backyard bomb shelters. Radiation is the stuff that leads meltdowns at nuclear power plants to contaminate the ocean and make land uninhabitable for hundreds of years.
AAP also advocates for more research into the human health impacts of cell phone radiation, particularly when it comes to children. One current problem? Federal Communications Commission tests used to determine cell phone radiation is based on the devices’ possible effect on large adults — not kids. Children’s skulls are thinner and can absorb more radiation (4)
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.
The industry’s $4.7 million contribution to the WHO appears to have had its most telling effect in May 2011, when the WHO convened scientists in Lyon, France, to discuss how to classify the cancer risk posed by cell phones. The industry not only secured “observer” status at Lyon for three of its trade associations; it placed two industry-funded experts on the working group that would debate the classification, as well as additional experts among the “invited specialists” who advised the group.38
The most compelling evidence though comes from a Swedish team of cancer experts whose research stretches back 15 years. The results clearly demonstrate “a consistent association between long-term use of cell phone and cordless phones and glioma and acoustic neuroma”. Overall, they found that using a cell phone for more than a decade significantly increases the risk of a malignant tumour by almost two times with an analogue cell phone and by nearly four times with a digital phone. Interestingly, the risks were even higher for people who had started using mobiles as teenagers.
