In 2011, two small studies were published that examined brain glucose metabolism in people after they had used cell phones. The results were inconsistent; whereas one study showed increased glucose metabolism in the region of the brain close to the antenna compared with tissues on the opposite side of the brain (26), the other study (27) found reduced glucose metabolism on the side of the brain where the phone was used.
BACKGROUND: Dental amalgam is composed of approximately 50% elemental mercury. Despite concerns over the toxicity of mercury, amalgam is still the most widely used restorative material. Wi-Fi is a rapidly using local area wireless computer networking technology. To the best of our knowledge, this is the first study that evaluates the effect of exposure to Wi-Fi signals on mercury release from amalgam restorations.
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?
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.

Suitable for most popular Smart Phones & iPads. Cellsafe’s groundbreaking technology is NOT a shield and will not interfere with transmission signal or with call reception.
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]
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
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.
We’re living in a wireless technology age, but there’s some evidence that exposure to electromagnetic radiation from cell phones and wireless devices could increase your risk of certain cancers and tumors. However, more research is needed. In the meantime, I recommend practicing the precautionary principle. Some great cell phone safety tips include:
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.
"In conclusion, contrary to the assurances implied by Karipidis et al., existing scientific evidence clearly indicates that there are potential health risks for students and staff from microwave RF-EMR exposure levels found at schools from internal and external wireless infrastructure. ARPANSA should immediately recommend that schools use wired Internet instead of WiFi as several responsible government agencies in other parts of the world have already done to reduce exposure of children, a sensitive population that need particular protection."
29. Carry your phone properly when you must carry it close to you. “If you must carry your cellphone on you, keep the keypad position toward your body and the back toward the outside to have the electromagnetic fields move away from you, rather than through you, according to Consumerist.” – Lizette Borreli, Teenage Girl Wakes to Samsung Galaxy S4 Catching Fire Under Pillow: 4 Ways to Make Your Cell Phone Safer, Medical Daily; Twitter: @lizcelineb
In addition, electrical and electronic devices of all kinds emit EM fields around their working circuits, generated by oscillating currents. Humans are in daily contact with computers, video display monitors, television screens, microwave ovens, fluorescent lamps, electric motors of several kinds (such as washing machines, kitchen appliances [like electric can openers, blenders, and mixers], water pumps, etc.) and many others. A study of bedroom exposure in 2009 showed the highest ELF-EF from bedside lights and the highest ELF-MF from transformer devices, while the highest RF-ELF came from DECT cordless phones and outside cellphone base stations; all exposures were well below International Commission on Non-Ionizing Radiation Protection (ICNIRP) guideline levels.[16]
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.
The present study was designed to determine the possible protective effects of melatonin on oxidative stress-dependent testis injury induced by 2.45-GHz electromagnetic radiation exposure (60 min/day for 30 days). Lipid peroxidation levels were shown to be higher in melatonin-supplemented group compared to EMR only and controls, as well as reduced glutathione and glutathione peroxidase levels. Vitamin A and E concentrations decreased in exposure group, and melatonin prevented the decrease in vitamin E levels. In conclusion, wireless (2.45 GHz) EMR caused oxidative damage in testis by increasing the levels of lipid peroxidation and decreasing in vitamin A and E levels. Melatonin supplementation prevented oxidative damage induced by EMR and also supported the antioxidant redox system in the testis.
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."

The possible effects of RF-EMR due to cellular phone and Wi-Fi usage should be investigated by researchers in more detail because the harmful effects should be proven instead of just implying the possible detrimental effects. Our findings display contrast results when we compared them with existing information and beliefs. We have not seen any difference between sperm parameters and cell phone and wireless internet usage. Larger population based studies combined with the laboratory results are needed to reach a definitive conclusion.
