METHODS: Standard class V cavities were prepared on the buccal surfaces of 20 non-carious extracted human premolars. The teeth were randomly divided into 2 groups (n = 10). The control group was stored in non-environment. The specimens in the experimental groups were exposed to a radiofrequency radiation emitted from standard Wi Fi devices at 2.4 GHz for 20 min. The distance between the Wi-Fi router and samples was 30 cm and the router was exchanging data with a laptop computer that was placed 20 m away from the router. The concentration of mercury in the artificial saliva in the groups was evaluated by using a cold-vapor atomic absorption Mercury Analyzer System. The independent t test was used to evaluate any significant differences in mercury release between the two groups.
I am suffering such pain from other peoples’ wifi that I have to drive out to a wood at night in order to sleep.The pain is all in the middle of my body,my legs tremble,I feel sick and my heart races.I keep telling everybody but nobody cares because all they want to do is be online,they are all addicted.One day people like me will be the only ones left as everyone else will have died with brain cancer.But why should their stupidity and ignorant selfishness be able to inflict all this misery on me,and also on all the birds,animals insects and plants which will all die out too.All that is good in the world is being destroyed for the sake of people chatting online whenever they just feel like it,are humans really this shallow,because I’m not.I feel like I’m living in a terrible nightmare or ‘The Bodysnatchers’ because nobody will believe what I can feel EMFs are doing to us.
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.”
Wi-Fi transmissions consist of sequences of RF burst signals or pulses ranging in duration depending on the amount of data being carried by a pulse(15). The proportion of time that Wi-Fi transmits RF signals is called the duty cycle. Joseph et al.(14) in measuring Wi-Fi in 176 different urban locations (outdoors, homes, offices) found a median duty cycle of 1.4% over all the measurements. Particularly in schools, Khalid et al.(10) in measuring Wi-Fi in six schools found a mean duty cycle from the access points of 4.8%. In our study duty cycle was measured separately for the 2.45 and 5 GHz transmissions when performing the stationary Wi-Fi measurements in the centre of the classroom. The median duty cycle for 23 schools that were measured in the current study was 6.3 and 2.4% for 2.45 and 5 GHz transmissions, respectively.
✅ PROTECT YOUR HEAD & BODY FROM RADIATION: It is scientifically proven that it’s best to keep your phone away from your body because the radiation exposure often exceeds FCC regulations. That’s why our emf protection cell phone radiation shield will immediately negate symptoms such as headaches, dizziness, memory loss, anxiety, fatigue and much more.
The FCC sets the maximum amount of thermal radiation (heat) that cell phones are permitted to emit.  This limit is measured as the amount of radiation absorbed by a user and is known as the specific absorption rate (SAR). In 1996 the SAR for cell phone radiation was set at a maximum of 1.6 watts of energy absorbed per kilogram of body weight. Manufactures of cell phones must test their products to ensure that they meet this standard. Random tests of phones on the market by FCC scientists further ensure that radiation levels meet FCC guidelines. 
Radiofrequency radiation is a form of electromagnetic radiation. Electromagnetic radiation can be categorized into two types: ionizing (e.g., x-rays, radon, and cosmic rays) and non-ionizing (e.g., radiofrequency and extremely low frequency, or power frequency). Electromagnetic radiation is defined according to its wavelength and frequency, which is the number of cycles of a wave that pass a reference point per second. Electromagnetic frequencies are described in units called hertz (Hz).
Turn Off WiFi Before Bed: This is one of our favorites in our Tech Wellness Top 10 easy ways to make wireless safer: We call it our Wi-Fi Kill-switch so you don't have to get close the Router. It's as important as WiFi Router placement. The simple step of hitting the off switch can lead to a better night’s sleep. Or, try this timer that can shut or kill that nasty Wifi energy any time of day or night. When on, a WiFi signal may interfere with our brains during sleep, so by turning it off we reduce exposure and hopefully rest more deeply.
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.
This study was aimed at investigating the alteration of antibiotic resistance of Klebsiella pneumonia, after exposure to Wi-Fi 2.4 GHz electromagnetic radiofrequency radiation from a Wi-Fi router for 3, 4.5 or 8 hours. The findings of this study show a statistically significant rise in the sensitivity of Klebsiella pneumoniae to different antibiotics after 4.5 hours of exposure to 2.4 GHz Wi-Fi radiation, followed by a fall after 8 hours of exposure. These observations can be interpreted by the concept of non-linearity in the responses of Klebsiella pneumoniae to different antibiotics after exposure to electromagnetic radiofrequency radiation.
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.
Cell phone storage in front pockets has been linked to poor fertility and higher chances of miscarriage and childhood cancer.  According to the Cleveland Clinic Center for Reproductive Medicine, semen quality "tended to decline as daily cell phone use increased."  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. 
Wireless internet (Wi-Fi) providers have become essential in our daily lives, as wireless technology is evolving at a dizzying pace. Although there are different frequency generators, one of the most commonly used Wi-Fi devices are 2.4GHz frequency generators. These devices are heavily used in all areas of life but the effect of radiofrequency (RF) radiation emission on users is generally ignored. Yet, an increasing share of the public expresses concern on this issue. Therefore, this study intends to respond to the growing public concern. The purpose of this study is to reveal whether long term exposure 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.
This is a stupid article. We get electromagnetic radiation from radios, baby monitors, alarm systems, even the Earth itself. And even if we own none of that we still get it from out neighbors. It’s harmless, after all we been exposed to it forever from our planet. Unless you plan on wrapping yourself in foil you will escape it. Not that it matters, it does no harm in these low doses.
Funding friendly research has perhaps been the most important component of this strategy, because it conveys the impression that the scientific community truly is divided. Thus, when studies have linked wireless radiation to cancer or genetic damage—as Carlo’s WTR did in 1999; as the WHO’s Interphone study did in 2010; and as the US National Toxicology Program did in 2016—industry spokespeople can point out, accurately, that other studies disagree. “[T]he overall balance of the evidence” gives no cause for alarm, asserted Jack Rowley, research and sustainability director for the Groupe Special Mobile Association (GSMA), Europe’s wireless trade association, speaking to reporters about the WHO’s findings.22

The HPA also says that due to the mobile phone's adaptive power ability, a DECT cordless phone's radiation could actually exceed the radiation of a mobile phone. The HPA explains that while the DECT cordless phone's radiation has an average output power of 10 mW, it is actually in the form of 100 bursts per second of 250 mW, a strength comparable to some mobile phones.
All values were far below International Commission on Non-Ionizing Radiation Protection’s (ICNIRP) reference values, but most mean levels measured were above the precautionary target level of 3–6 µW/m2 as proposed by the Bioinitiative Report ….however the ICNIRP guidelines are based on short-term heating (thermal) effects, and are therefore not relevant to decide on the appropriateness of long-term exposure.
The aim of this study was to investigate the possible protective role of selenium and L-carnitine on oxidative stress induced by 2.45-GHz radiation (60min/day for 28 days) in heart of rat. Electromagnetic radiation exposure was found to cause oxidative stress in the heart of rats. There is also an apparent protective effect of selenium and L-carnitine by inhibition of free radical formation and support of the antioxidant redox system.
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.
I’ve tried to stop using my laptop PC whose WiFi antennas I think were at the front edge on my lap since a highly skeevy lesion manifested at about my waistline. Same for any other wifi devices; I use a table or desk or bench or another chair to set it on now, not the lap. Testing the lesion naturally as if it might be cancerous, making it go away.
The WHO began to study the health effects of electric- and magnetic-field radiation (EMF) in 1996 under the direction of Michael Repacholi, an Australian biophysicist. Although Repacholi claimed on disclosure forms that he was “independent” of corporate influence, in fact Motorola had funded his research: While Repacholi was director of the WHO’s EMF program, Motorola paid $50,000 a year to his former employer, the Royal Adelaide Hospital, which then transferred the money to the WHO program. When journalists exposed the payments, Repacholi denied that there was anything untoward about them because Motorola had not paid him personally. Eventually, Motorola’s payments were bundled with other industry contributions and funneled through the Mobile and Wireless Forum, a trade association that gave the WHO’s program $150,000 annually. In 1999, Repacholi helped engineer a WHO statement that “EMF exposures below the limits recommended in international guidelines do not appear to have any known consequence on health.”34
Bluetooth allows your phone to communicate with other devices, such as the hands-free option in your car or your printer. If accessed by someone else though, they could misuse it to access your information or intercept your calls. Turn off the Bluetooth on your phone and turn it on only when you need to connect with other device. Many phones also allow users to set passcodes or additional security levels on their Bluetooth as well. Use all available options to increase your privacy.
The Working Group indicated that, although the human studies were susceptible to bias, the findings could not be dismissed as reflecting bias alone, and that a causal interpretation could not be excluded. The Working Group noted that any interpretation of the evidence should also consider that the observed associations could reflect chance, bias, or confounding rather than an underlying causal effect. In addition, the Working Group stated that the investigation of risk of cancer of the brain associated with cell phone use poses complex methodologic challenges in the conduct of the research and in the analysis and interpretation of findings.
Kids are a perceptive lot, and they won’t like it if they’re given a device that doesn’t look the part. Thankfully for them (and for your wallet), the Honor 7X looks the business, for a bargain price. It’s one of the first devices in the budget price range to come with a bezel-less design akin to the Galaxy S8 and iPhone X — at a fraction of the price.
A method of simulating thermal mapping of positioning laptop on laps of an adult man was developed. To tackle this problem, we exploited computer simulation and, to make the simulation close to the actual problem, we created 3D models of an actual laptop (Sony FW 590 Gab), antennas, and human phantom with inhomogeneous body, large number of tissues, and dispersion properties. We employed a commercial laptop Wi-Fi antenna at 2.4 GHz and a dipole antenna at 5 GHz, thermal sources with radiation powers, and human body voxel consisting of 97 tissues which were described previously. In the simulation, maximum SAR in human body was calculated 0.37 × 10−3 and 0.13 × 10−1 (W/kg) at 2.4 and 5 GHz, respectively, which was negligible according to IEEE standards; thus, the major calculated temperature elevation was due to laptop thermal sources. The temperature in glans penis, lap skin, lap muscles, and testes increased up to 37.8, 42.9, 38.8, and 37.2 °C, respectively, which was in line with clinical studies of thermal effect. Hence, the proposed method can be replicated for other scenarios. It is worth noting that the presented result cannot be easily generalized to other devices or human models. However, the whole method is replicable for similar phenomena. The recommended subject for future works can be used with the presented method for determining the effect of laptop and other devices on adult pregnant women and similar cases.
Keep in mind that even if someone doesn’t have access to your phone, it might be possible for them to access your online account. Online accounts can include your wireless carrier account, call logs, your email or social media accounts, your Google Play/Apple AppStore, or iCloud account. Update the passwords and security questions for those accounts to ensure someone else can’t get access.
Members of the public often ask about the cumulative exposure that a child receives when using a Wi-Fi device in a classroom in which a number of children are simultaneously using Wi-Fi. When downloading files, most of the transmissions will be from the access point, not the students’ device. When downloading and uploading only a portion of the maximum capacity of a network would be used even in a classroom filled with children using Wi-Fi. The Wi-Fi network divides RF transmissions among the access points and client devices therefore the individual RF exposure to a child in a classroom that is using a device consists of sequential exposures from all active devices, the majority of which are located at some distance away(15). For the majority of schools (20) the measurements in the current study were conducted in an empty classroom (to avoid lesson disruption) with an access point and one laptop. In three schools, measurements were conducted with students or teachers present and using Wi-Fi devices. A comparison between measurements conducted in empty classrooms and classrooms with multiple students/teachers using Wi-Fi showed no significant difference in the RF levels (p > 0.1 for all); although this may have been due to low numbers (only three schools measured with multiple users in the classroom).
Hardell had already attracted the industry’s displeasure back in 2002, when he began arguing that children shouldn’t use cell phones. Two scientists with industry ties quickly published a report with the Swedish Radiation Authority dismissing Hardell’s research. His detractors were John D. Boice and Joseph K. McLaughlin of the International Epidemiology Institute, a company that provided “Litigation Support” and “Corporate Counseling” to various industries, according to its website. Indeed, at the very time Boice and McLaughlin were denigrating Hardell’s work, the institute was providing expert-witness services to Motorola in a brain-tumor lawsuit against the company.41

If you are concerned about the possible health effects of radio wave radiation emitted by your cell phone, your options are simple and cheap. This kind of radiation is at its highest levels nearest the antenna. Also, not all cell phones are created equal. Sar Shield offers a useful radiation chart for cell phones that provides an accurate "Sar rating" for every cell phone model. It's important to realize that at these low radiation levels, if you keep the cell phone away from your head and body, you are perfectly safe. However, if you'd rather not use a headset, then there are plenty of resources to obtain a radiation shield for your phone.
There was a negative correlation between the cell phone usage duration and the total sperm count (r = −0.064, p = 0.04). Similarly, there was also a negative correlation between the wireless internet usage duration and the total sperm count (r = −0.089, p = 0.019). Otherwise there were no significant correlations among the other four main question branches (cell phone usage time, cell phone carriage habits, wireless internet usage time. and internet connection type) and sperm parameters.
The aim of this study was to investigate the effects of electromagnetic radiation (EMR) on the pancreas tissue of young rats and the ameliorative effect of Gallic acid (GA). Six-week-old, 48 male rats were equally divided into four groups: Sham group, EMR group (2.45 GHz), EMR (2.45 GHz)+GA group (30 mg/kg/daily) orally and GA group (30 mg/kg/daily). After 30 days, serum and pancreatic tissue samples were harvested for biochemical, histopathological and immunohistochemical analysis. Serum amylase, lipase, glucose, and tissue malondialdehyde, total oxidant status and oxidative stress index were increased, whereas total antioxidant status decreased in the EMR group. The histopathological examination of the pancreases indicated slight degenerative changes in some pancreatic endocrine and exocrine cells and slight inflammatory cell infiltrations in the EMR group. At the immunohistochemical examination, marked increase was observed in calcitonin gene related protein and Prostaglandin E2 expressions in pancreatic cells in this group. There were no changes in interleukin-6 expirations. GA ameliorated biochemical and pathological findings in the EMR+GA group. These findings clearly demonstrate that EMR can cause degenerative changes in both endocrine and exocrine pancreas cells in rats during the developmental period and GA has an ameliorative effect.
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 recent report by the International Agency for Research on Cancer (IARC) about the potential connection between cell phone use and cancer is big news to media outposts and the general public. Prior to the report, scientists told us no evidence existed that cell phones were carcinogenic. And now? According to the IARC, research now proves that there is evidence that cell phones might in fact be carcinogenic. The potential villains in this scenario are radiofrequency electromagnetic fields, which are emitted by a cell phone’s antenna, and which the agency says may be linked to two types of brain cancer.
The increasing use of Wi-Fi in schools and other places has given rise to public concern that the radiofrequency (RF) electromagnetic fields from Wi-Fi have the potential to adversely affect children. The current study measured typical and peak RF levels from Wi-Fi and other sources in 23 schools in Australia. All of the RF measurements were much lower than the reference levels recommended by international guidelines for protection against established health effects. The typical and peak RF levels from Wi-Fi in locations occupied by children in the classroom were of the order of 10-4 and 10-2% of the exposure guidelines, respectively. Typical RF levels in the classroom were similar between Wi-Fi and radio but higher than other sources. In the schoolyard typical RF levels were higher for radio, TV and mobile phone base stations compared to Wi-Fi. The results of this study showed that the typical RF exposure of children from Wi-Fi at school is very low and comparable or lower to other sources in the environment.
