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.
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.

To date, there are a few long-term studies, very few in humans and even fewer epidemiological studies, apart from the studies on laptops with small numbers of study subjects. It is also far too early to generate reliable figures at this time. However, there are indications that especially newborns, children, or adolescents are particularly vulnerable as has been presented in detail by the research teams of Nazırogˇ lu, Atasoy, Margaritis/ Panagopoulos, Orendacˇ ova, Othmann, Ozorak, Sangun, Shahin and Yuksel. The experiments were carried out with rats or mice, in some cases as long-term studies (up to 1 year). In this context, it is important to note that rats and mice used in laboratories have a life expectancy of perhaps two years. This at least allows us to infer that human children and adolescents have to be protected from possible increased risks. In the study of Margaritis et al. (2014), the authors point out that the exposure levels from Bluetooth (0.3 V/m) and Wi-Fi routers (here 2.1 V/m) showed greater effects than cell phone radiation sources with much higher field strengths. This may coincide with the findings of the papers by von Klitzing, which stated that the power-dependent pulse of 10 Hz (1 ms) from Wi-Fi routers triggered reactions. Kumari et al. observed in a study from 2012 that higher levels of ROS in the liver suppress antioxidant enzymes and that lower levels cause an increase. This could be a key to further mechanisms as to how or whether tissue damage occurs or perhaps not. Likewise, the polarization of RF radiation (Meena et al. 2014, Panagopoulos et al. 2015) should also receive additional attention.
When a group of Danish ninth graders experienced difficulty concentrating after sleeping with their cell phones by their head, they performed an experiment to test the effect of wireless Wi-Fi routers on garden cress. One set of plants was grown in a room free of wireless radiation; the other group grew next to two routers that released the same amount of radiation as a cell phone. The results? The plants nearest the radiation didn’t grow. [6]
It’s been suggested that sleeping near a phone, in a home with Wi-Fi, or in an apartment building with many Wi-Fi signals can create chronic sleep problems as the constant bombardment of Wi-Fi pollution interferes with falling asleep and sleep patterns. For many, sleep deprivation is just the start for larger problems. The development of depression and hypertension have also been linked to inadequate sleep. [3]

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
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.
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.
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. [56] 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. [44] [71] 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, [57] but the average user in the study had less than eight years of cell phone exposure. [56] 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." [58]
To shed a bit more light on it – powerline electromagnetic fields have different (though not necessarily better) biological effects. 50/60Hz powerline fields alter ion transport across intra- and inter-cellular membranes, accelerating or inhibiting chemical reactions, depending on the reaction. Also within the reception range of bulk brainwave action. So not the greatest thing for physical and mental health. As you go higher in freq range, the effects become more just thermal and neurostimulative at high enough field strength. From 400MHz on up the issue becomes field-excitation of mechanical shaking of DNA strands resulting in sequence breakage and translocations – not great for cancer risk… for those really bored and curious, read the studies bibliography of IEEE C95.1-2005. I found C95 and its underlying studies to be the most helpful body of work when setting the safety standards for inductive wireless charging.

If you think your heart races when surrounded by wireless networks or 3G or LTE cell phones, it may not be in your head. A study involving 69 subjects reported that many of them experienced a real physical response to electromagnetic frequencies. Exactly what was the physical response? Increased heart rate — similar to the heart rate of an individual under stress. [14]

Things didn’t end well between George Carlo and Tom Wheeler; the last time the two met face-to-face, Wheeler had security guards escort Carlo off the premises. As president of the Cellular Telecommunications and Internet Association (CTIA), Wheeler was the wireless industry’s point man in Washington. Carlo was the scientist handpicked by Wheeler to defuse a public-relations crisis that threatened to strangle his infant industry in its crib. This was back in 1993, when there were only six cell-phone subscriptions for every 100 adults in the United States. But industry executives were looking forward to a booming future.1

To be sure, the industry could not have been pleased with some of the Interphone study’s conclusions. The study found that the heaviest cell-phone users were 80 percent more likely to develop glioma. (The initial finding of 40 percent was increased to 80 to correct for selection bias.) The Interphone study also concluded that individuals who had owned a cell phone for 10 years or longer saw their risk of glioma increase by nearly 120 percent. However, the study did not find any increased risk for individuals who used their cell phones less frequently; nor was there evidence of any connection with meningioma.36

Purpose: This article is a systematic review of studies on the effects of non-ionizing radiation at the microwave (MW) frequency of 2.45 GHz (2450 MHz), which is predominantly used in WLAN/Wi-Fi applications (wireless local area network) and microwave ovens. Newer WLAN standards also use the frequency ranges of 5 GHz, 6 GHz, and 60 GHz. WLAN, referred to generically in this review also as Wi-Fi, has become the technology of choice for many wireless applications because providers do not require a license, making the service free to users. To meet users’ desire to be online all the time, more and more WLAN antennas (access points, femtocells, routers) emitting pulsed 2.45 GHz radiation are being installed at libraries, hospitals, hotels, airports, railway stations, shopping malls, public places, and in buses, subways, and passenger trains. Wi-Fi consoles are used to play games. Office and household appliances are also fitted with Wi-Fi antennas. Residential routers often contain two Wi-Fi transmitters. As part of its digital learning initiative, the German Conference of Ministers of Education has decided to provide all schools with Wi-Fi networks. The extensive body of research on the health risks of Wi-Fi radiation is generally not considered by policy-makers or in the public debate.
I think it might be part of the problem with all these kids losing it in the last decade and a half. Just something to think about. Maybe they should start building “wifi free”restaurants and buildings. They have been warning people since before they even started using it on a commercial bases that wifi was going to have serious effects on the human body. There’s just so much of a “hey as long as it doesn’t bother me I don’t care” attitude. I mean think about it. Now I’m not saying this in a negative way but look at the turnaround in public opinion about gay marriage. I mean it went from a hotly debated topic to “ah well they ain’t hurting anybody so let them do what they want. Except in the red states and if you notice a lot of those states are lacking saturated wifi signals. Just something to think about
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.
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. [1] 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 [41] found a "decreased risk for high-grade glioma," a malignant brain tumor, and a 2005 Swedish study [42] also found a "decreased odds ratio" for developing glioma as well as meningioma, another type of brain tumor.
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]
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.

Safety standards do exist for radio frequency radiation emissions, but these standards are only based on thermal heating effects. That is to say they only consider these exposures to be harmful if they heat tissue. But these safety standards do not protect us from adverse biological effects which are thought to be the precursor to serious diseases. Scientists have already raised the alarm regarding this issue.
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. [59] 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. [21] The American Heart Association includes cell phones on its list of "devices that may interfere with pacemakers." [60]
This study investigated the effect of 2.45 GHz microwave radiation (2 h/day for 45 days) on biomarkers within Wistar rats. A significant decrease (P < 0.05) was recorded in the level of pineal melatonin of exposed group as compared with sham exposed, while a  significant increase (P < 0.05) in creatine kinase, caspase 3, and calcium ion concentration was observed in whole brain of exposed group of animals as compared to sham exposed. The study concludes that a reduction in melatonin or an increase in caspase-3, creatine kinase, and calcium ion may cause significant damage in brain due to chronic exposure of these radiations. These biomarkers clearly indicate possible health implications of such exposures.
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).
Electromagnetic fields have been shown to disrupt melatonin production. In turn, sleep and overall health are disrupted. Charge your phone in another room. If you must be available to loved ones during the night, keep a corded phone next to your bed, or keep the cell phone on the other side of the room. (See more about safe sleeping in the post Sleep, Melatonin and Electronic Devices.)
PURPOSE: MicroRNAs (miRNA) play a paramount role in growth, differentiation, proliferation and cell death by suppressing one or more target genes. However, their interaction with radiofrequencies is still unknown. The aim of this study was to investigate the long-term effects of radiofrequency radiation emitted from a Wireless Fidelity (Wi-Fi) system on some of the miRNA in brain tissue.

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.
High frequency, specifically 2.45 GHz Wi-Fi radiation, induces a decrease in sperm parameters along with an increase in apoptosis-positive cells and caspase-3 activity in the seminiferous tubules of Wistar rats, specially in 7-hour group. It reduced seminal vesicle weight following 2.45 GHz exposure. Considering the progressive privilege of 2.45 GHz wireless networks in our environment, we concluded that there should be a major concern about the time-dependent exposure of our body to the higher frequencies of Wi-Fi antenna.
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.
An excessive production of reactive oxygen substances (ROS) and reduced antioxidant defence systems resulting from electromagnetic radiation (EMR) exposure may lead to oxidative brain and liver damage and degradation of membranes during pregnancy and development of rat pups. In the EMR groups, lipid peroxidation levels in the brain and liver were increased following EMR exposure; however, the glutathione peroxidase (GSH-Px) activity, and vitamin A, vitamin E and β-carotene concentrations were decreased in the brain and liver. Glutathione (GSH) and vitamin C concentrations in the brain were also lower in the EMR groups than in the controls; however, their concentrations did not change in the liver. In conclusion, Wi-Fi-induced oxidative stress in the brain and liver of developing rats was the result of reduced GSH-Px, GSH and antioxidant vitamin concentrations. Moreover, the brain seemed to be more sensitive to oxidative injury compared to the liver in the development of newborns.

This study used Drosophila as model organisms to assess the effects of various EMF sources (short time daily for 3-7 days) on apoptotic cell death of follicles during oogenesis and reproductive capacity (fecundity) decline. Sources included: 900/1800 MHz mobile phone, 1880-1900 MHz wireless base, wireless handset, mobile phone-handset combination, 2.44 GHz wireless network (Wi-Fi), 2.44 GHz bluetooth, 92.8 MHz FM generator, 27.15 MHz baby monitor, 900 MHz CW RF generator and microwave oven’s 2.44 GHz RF and magnetic field components. All EMF sources used created statistically significant effects regarding fecundity and cell death-apoptosis induction, even at very low intensity levels well below ICNIRP’s guidelines, suggesting that Drosophila oogenesis system is suitable to be used as a biomarker for exploring potential EMF bioactivity.
