A series of studies testing different scenarios (called simulations by the study authors) were carried out using incidence data from the Nordic countries to determine the likelihood of detecting various levels of risk as reported in studies of cell phone use and brain tumors between 1979 and 2008. The results were compatible with no increased risks from cell phones, as reported by most epidemiologic studies. The findings did suggest that the increase reported among the subset of heaviest regular users in the Interphone study could not be ruled out but was unlikely. The highly increased risks reported in the Swedish pooled analysis were strongly inconsistent with the observed glioma rates in the Nordic countries (24).
In the current study, the pattern of the response of E coli to Wi-Fi and RF simulator radiation was identical. The maximum differences in the diameters of inhibition zones were observed between 6 and 9 hours of the bacterial exposure to radiation (Figures 1 and 2). After 12 hours of exposure, the bacterial responses to radiation as a stressor led to returning to the preexposure status.
There has been no rise in the rate of brain cancers despite a massive increase in the use of cell phones. If cell phones were causing cancer we could expect a significant rise in the rate of brain and other related cancers. According to the National Cancer Institute, there was no increase in the incidence of brain or other nervous system cancers between the years 1987 and 2005 despite the fact that cell phone use dramatically increased during those same years. [6] Between 2004 and 2010 there was still no significant change in the incidence rate of brain tumors. Between 2004 and 2010 there was a slight increase from 209 cases to 221.8 cases per 100,000 people, but this slight increase was attributed to better tracking and recording of cases. [43] During the same time period, cell phone use increased 62.7% from 182,140,362 subscribers in 2004 to 296,285,629 in 2010. [44]
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.
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.
This is extremely controversial but we can’t ignore that plenty of animal models indicate that exposure to electromagnetic radiation increases the risk of tumor development. While human studies are rare, reports and case studies abound. One such case involves a young 21-year-old woman who developed breast cancer. What makes this case unique was that her family did not have a predisposition to breast cancer… and she developed the tumor right on the spot she carried her cell phone in her bra. [15]

the Environmental Working Group is suspending publication of the EWG guide to cell phones until the FCC makes the responsible decision to require cell phone makers to generate and disclose data about device and network emissions under real-world conditions. We strongly believe that as cell phones become more powerful and ubiquitous, it is critical that people have a right to know how much radiation they can expect their cell phones to generate. As things now stand, the FCC’s cell phone safety rules are as obsolete as the StarTac.

Cooper's prototype arrived on the market a decade later at the staggering price of $3,995. Designed by Rudy Krolopp, it was known as the Motorola DynaTAC 8000X, or simply "the brick.” Featuring 20 large buttons and a long rubber antenna, it measured about 11 inches high, weighed almost 2 pounds, provided one hour of battery life and could store 30 phone numbers.
That comes at something of a price though, and the chunky bezels mean it’s not the most stylish phone — though we do like the bronze edges. Still, it’s powerful, outstripping most other phones under $300, which makes it the perfect companion for a gaming-happy generation. The camera suffers from poor performance in low light, but is otherwise good. It’s also running on Google’s Android One operating system, which means the phone will be updated with the latest security patches and new features quickly and often, helping to keep your kid’s phone secure. It’s a great choice if solid performance and durability are preferred to flashy looks.
gamma rays produce virtually no electricity in the human body because the actual inherent energy of gamma rays that actually hits molecules is next to 0. for gamma rays to produce any electricity they would need to hit something much more dense – like lead and for you to generate any significant electricity from gamma rays hitting the earth you would need a huge slab of it.
14. Clean your phone regularly. “Newsflash: Your phone is dirty. Like, really dirty. It’s crawling with germs and bacteria that can cause acne and even nasty rashes. And if you take your phone to the bathroom often, it could also be covered in fecal matter.” – Amanda Hawkins, 5 Ways Your Phone Is Ruining Your Skin, Good Housekeeping; Twitter @goodhousemag
Listeria monocytogenes ... was recognized as the main cause of neonatal infection, meningitis, and sepsis. Listeria infection in adult patients is related to immunocompromised systems like HIV infection, organ transplants, individuals who have received corticosteroids, and immunosuppressant drugs for their malignancies. Escherichia coli known as E coli is a common cause of life-threatening infections such as bloodstream and urinary tract infections, otitis media, and other complications.
The present study was designed to determine the effects of 2.45 GHz EMR (60 min/day for 28 days) on the brain antioxidant redox system and electroencephalography (EEG) records in rat, as well as examine the possible protective effects of selenium and L-carnitine. EMR-exposed animals showed lower concentration of vitamins A, C, and E than controls, although their concentrations were increased by selenium and L-carnitine supplementation. Animals which received selenium and L-carnitine in addition to EMR also showed lower levels of lipid peroxidation. Results indicate that L-carnitine and selenium seem to have protective effects on the 2.45 GHz-induced decrease of the vitamins by supporting antioxidant redox system.
Also, every inch you put between yourself and your Wi-Fi router significantly lowers the strength of the radiation your body encounters. “Put it this way,” Foster says. “During a call, your mobile phone is transmitting steadily at a strength maybe 100 times more powerful than Wi-Fi, and you’re holding the phone right against your head, and we still don’t find any health issues with that level of exposure.”
This study examined the possible ability of  2.45 GHz microwave radiation exposure (30 min) to modify the expression of genes that codify heat shock proteins (HSP) in the thyroid gland. Ninety minutes after radiation, HSP-90 and HSP-70 had decreased significantly (P<0.01); Twenty-four hours after radiation, HSP-90 had partially recovered and HSP-70 had recovered completely. There were few indications of lesions in the glandular structure and signs of apoptosis were negative in all radiated animals. The results suggest that acute sub-thermal radiation at 2.45 GHz may alter levels of cellular stress in rat thyroid gland without initially altering their anti-apoptotic capacity.

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 present study was designed to determine the effects of both Wi-Fi (2.45 GHz)- and mobile phone (900 and 1800 MHz)-induced electromagnetic radiation (60 min/day during pregnancy and growth) on oxidative stress and trace element levels in the kidney and testis of growing rats from pregnancy to 6 weeks of age. In conclusion, Wi-Fi- and mobile phone-induced EMR caused oxidative damage by increasing the extent of lipid peroxidation and the iron level, while decreasing total antioxidant status, copper, and GSH values. Wi-Fi- and mobile phone-induced EMR may cause precocious puberty and oxidative kidney and testis injury in growing rats.
Another place that you want to use your cell phone hands-free is in your vehicle. Driving and texting or driving and talking on a mobile device that you hold in one of your hands is dangerous and one of the leading causes of traffic accidents and deaths. However, there are times when it's necessary to use your cell phone while driving, such as when you're using a GPS app. For these times, a car-mounted mobile device holder is the answer. These attach to your vehicle's dash or windshield in several ways, including suction cups, magnets and double-sided adhesive tape. These devices allow you to rotate the cell phone so you can see it vertically and horizontally, and some make it so you can adjust the angle of sight.
In 2011, the American Cancer Society (ACS) stated that the IARC classification means that there could be some cancer risk associated with radiofrequency radiation, but the evidence is not strong enough to be considered causal and needs to be investigated further. Individuals who are concerned about radiofrequency radiation exposure can limit their exposure, including using an ear piece and limiting cell phone use, particularly among children.
There’s little chance you’d want to hand a Galaxy S8 to a child, but what about Samsung’s other offerings? Samsung’s A-range has been coming on in leaps-and-bounds the last few years, and the humble A5 makes a great choice as your kid’s phone. A 5.2-inch AMOLED screen is joined by good midrange specs that won’t let you down any time soon. It’s a metal-and glass-build, so you’re risking breakages (grabbing a case is advised), but it’s fully IP68-rated, so it’ll be able to survive a quick dip with no issues. The 3,000mAh is also impressive, so your kid shouldn’t be caught short. So what’s the catch? Like the Honor phone above, this phone will not work with either Verizon or Sprint, so think twice if you’re with either of those two — unless you’re looking to switch your plan soon.
The present study tested the effects of Wi-Fi (2.45 GHz for 1h) exposure on Ca(2+) influx, oxidative stress and apoptosis through TRPV1 channel in the murine dorsal root ganglion (DRG) and hippocampus of pentylentetrazol (PTZ)-induced epileptic rats. The cytosolic free Ca(2+), reactive oxygen species production, apoptosis, mitochondrial membrane depolarization, caspase-3 and -9 values in hippocampus were higher in the PTZ group than in the control although cell viability values decreased. The Wi-Fi exposure induced additional effects on the cytosolic Ca(2+) increase. However, pretreatment of the neurons with CPZ, results in a protection against epilepsy-induced Ca(2+) influx, apoptosis and oxidative damages. In conclusion, epilepsy and Wi-Fi in our experimental model is involved in Ca(2+) influx and oxidative stress-induced hippocampal and DRG death through activation of TRPV1 channels, and negative modulation of this channel activity by CPZ pretreatment may account for the neuroprotective activity against oxidative stress.
The aim of this study was to determine the structural changes in the frontal cortex, brainstem and cerebellum in the male rat brain due to electromagnetic wave exposure (900, 1800, 2450 MHz, 1h/day for 2 months). While the histopathological changes in the frontal cortex and brainstem were normal in the control group, there were severe degenerative changes, shrunken cytoplasm and extensively dark pyknotic nuclei in the EMR groups. Biochemical analysis demonstrated that the Total Antioxidative Capacity level was significantly decreased in the EMR groups and also Total Oxidative Capacity and Oxidative Stress Index levels were significantly increased in the frontal cortex, brainstem and cerebellum. Researchers concluded that EMR causes structural changes in the frontal cortex, brainstem and cerebellum and impairs the oxidative stress and inflammatory cytokine system. This deterioration can cause to disease including loss of these areas function and cancer development.
People who say cell phones are safe reference statements by the FCC and Food and Drug Administration (FDA) and point to peer-reviewed studies which conclude that cell phone use is not associated with an increased risk of brain tumors or the onset of other health problems. They contend there has been no increase in brain tumor rates despite hundreds of millions of people now using cell phones.
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
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.

The aim of this study was to investigate the effects of  prenatal and postnatal 2450 MHz electromagnetic field exposure (1hy/day from intrauterine or postnatal period) on the growth and development of female Wistar rats. Birth masses of the groups were similar (p > 0.05), however mass gain per day was significantly lower and the puberty was significantly later in the prenatal group. Brain and ovary TOS and OSI values in the prenatal group were significantly increased (p < 0.05) compared to the control group and serum LH levels of the prenatal and postnatal groups were increased, although serum FSH, and E2 values did not differ among the groups (p > 0.05). Histological examinations of the specimens revealed no statistically significant difference between the groups (p > 0.05). Exposure to 2450 MHz EMF, particularly in the prenatal period, resulted in postnatal growth restriction and delayed puberty in female Wistar rats. Increased TOS and OSI values in the brain and ovary tissues can be interpreted as a sign of chronic stress induced by EMF.

Reading the last paragraph of the previous section you might be saying “Ah hah! Microwaves! Microwaves are bad, they make things very hot and they could burn you!” That’s absolutely true. You would not want to build a human size microwave oven and stand inside it. Nor would you particularly enjoy being the target of the crowd-dispersing microwave cannons built and deployed by the U.S. military.
Researchers at Wageningen University in the Netherlands have reported that radiation from WiFi networks is harmful to trees. Problems observed included growth variations, and bleeding and fissures in tree bark. The researchers exposed 20 ash trees to various sources of radiation for three months. The tress closest to the WiFi source exhibited a lead-like shine on the leaves. The researchers also found that WiFi radiation is harmful to growing corn.
“So what can you do? Straighten up, first of all, says Kenneth Hansraj, M.D., an orthopedic surgeon in Poughkeepsie, New York. And carry device at chest height with head up, chest open and shoulder blades back. Move just your eyes downward. And then, take a break. Your neck is not supposed to stay stuck in one position for a long period. If you’re reading on a tablet or phone, stop every so often to swivel and tilt your head — up and down, then side to side.” – 3 Dumb Things We Do with Smartphones, Good Housekeeping; Twitter: @goodhousemag
