Last May the International Agency for Research on Cancer, an arm of the World Health Organization, made a big splash by classifying mobile phones as possibly carcinogenic to humans, based on an increased risk for glioma, a type of brain tumor. The group’s conclusions were based largely on two studies, including one of a few thousand Swedish adults.
Many scientists reject the notion that cell phones, which produce electromagentic fields, could cause cancer. That’s because the energy in these fields is far too low to damage cells, indeed these photons from cell phones — like those from  microwave ovens, smart meters, and Wi-Fi — all have energies about a million times too low to create mutant strands of DNA. Given this scientific fact what surprised me, in light of the IARC’s widely reported news release last year, was the understated play given to a study published last week in the British Medical Journal (see abstract) on cell phones and glioma.
Raised risks of glioma with mobile phone use, as reported by one (Swedish) study forming the basis of the IARC’s re-evaluation of mobile phone exposure, are not consistent with observed incidence trends in US population data, although the US data could be consistent with the modest excess risks in the Interphone study.
My conclusion is that you should trust in physics, which says the energy produced by cell phone electromagnetic waves is far too low to cause any harm. Plastic and Aluminum are supplied with 4 pre-drilled mounting holes, Vinyl labels do not have holes. Aluminum is one of the most durable material options offered, with excellent resistance to harsh weather conditions.
Polyethylene is a rust free, chip and crack resistant plastic (in white or yellow) treated for digital and screen printing. Polyethylene signs are an economical alternative to aluminum signs, without significant compromise on durability. You may not enter more than 1,000 characters for 'Change the sign text to read however you like, if necessary. There are advantages to cell phones: making emergency calls, catching up with friends, getting business done while on the bus, and so forth. Cell phones are a complex, low powered radiofrequency transmitter. Radiofrequency energy is a form of electromagnetic radiation. While our cell membranes appear to block non-ionizing radiation, we’re not sure how it influences our overall health long term.
The SAR (specific absorption rate) is a measure of radiofrequency energy absorption by the body. The International Agency for Research on Cancer (World Health Organization) has deemed electromagnetic fields from cell phones as possibly carcinogenic (same as lead, chloroform and engine exhaust). For every study that outlines something negative related to cell phones, there is another study showing no effect.
However, even if we don’t yet have solid data, we can make some informed guesses based on what we do know about radiation and the way the body works. When the blood-brain barrier loses integrity, it gets leaky, and microorganisms moving around the body have a better chance of entering the brain space.
Leakage across the blood-brain barrier also appears in the pathophysiology of multiple sclerosis (MS). Another thought is that increased cell phone usage can lead to increased oxidative stress (with concurrent decreases in antioxidant function).
Whatever the mechanism, it seems clear that cell phones may have wide-ranging health effects on several body organs and systems.
When we hold a cell phone by our head, the electromagnetic fields can penetrate up to 6 cm inside the brain. There are some associations between cell phone (and cordless phone) use and brain cancer, with the highest risk in those under the age of 20 years.


Brain glucose metabolism around the area of the cell phone antenna tends to increase while the cell phone is in use (by the head). More cell phone use is correlated to less sperm motility, altered sperm morphology (in other words, funny-looking wigglers) and a decreased sperm count. If pregnant women use cell phones, there seems to be a greater chance that their children will have behaviour problems or hyperactivity. While the exact relationship isn’t clear, it seems that cell phone use might affect sleep patterns and neuroendocrine function.
There are associations between cell phone use and the development of non-Hodgkin’s lymphoma. Young brains continue to develop well into the third decade of life, and of course our brains are at their busiest when we are young.
So, the brains of children and teenagers may be more susceptible to electromagnetic radiation. Modern technology has been implicated as a cause of various skin conditions, often to the hands and face. We think we’re better multi-taskers than we really are, and cell phone use while driving is no exception. Some research suggests that talking on a cell phone while driving is effectively like driving while impaired. As a result, many regions have banned cell phones for drivers outright, or restricted cell phone use to hands-free devices only. Despite the difficulty of producing cell phone materials, we don’t treat our phones as permanent investments. It’s still not clear exactly how risky cell phones are for both us and our environment.
Luckily, we can implement simple, low-cost preventive measures right now to help keep ourselves safe.
When you must discard your cell phone, make sure to recycle it properly or donate it (see resources below).
A major study, known as COSMOS, was launched in 2010 in Europe, tracking cells phone users for 20 years. To learn more about making important improvements to your own nutrition and exercise program, check out the following 5-day video courses. They’re probably better than 90% of the seminars we’ve ever attended on the subjects of exercise and nutrition (and probably better than a few we’ve given ourselves, too). No Cell Phone Usage nameplate includes color choices for both the sign plate and the frame - at no additional charge. I forget about them and instead focus on important stuff, like what I’m going to eat for lunch. With a cell phone in our pocket or by our head, slight temperature increases might disrupt cellular functioning. Rats exposed to 900 MHz radiofrequency (the strength of the old Zack Morris phone) show a leaky brain. Still, observational studies have found little association in humans between cell phone use and the development of MS (though data have indicated that MS symptoms might get worse with cell phone use).
More oxidative stress is associated with a host of problems, such as damage to DNA, enzymes, lipids and proteins. Association between number of cell phone contracts and brain tumor incidence in nineteen U.S.


Data isn’t consistent here and variations might be due to the type of cell phone used. Animal studies have shown decreases in testicular size and sperm cell death with exposure to electromagnetic radiation.

Indeed, many concerned parents and phone-happy kids have reported symptoms related to cell phone use, such as sleep problems, dizziness, fatigue, asthma, behavioral problems, etc. Is this because the phones store things like phone numbers and addresses (which means we don’t have to work to remember them), or because we’re distracted by texting, or some other reason? National Highway Traffic Safety Administration (NHTSA) estimates that of all the traffic accidents caused by distracted drivers, about 20% of those involved cell phone use.
If you can ride the car on the train that prohibits cell phones, you’ll be exposed to less electromagnetic radiation.
Electromagnetic field treatment protects against and reverse cognitive impairment in Alzheimer’s disease mice. Increased protein synthesis by cells exposed to a 1,800-MHz radio-frequency mobile phone electromagnetic field, detected by proteome profiling. Radiofrequency electromagnetic fields (UMTS, 1,950 MHz) induce genotoxic effecs in vitro in human fibroblasts but not in lymphocytes.

Effects of mobile phone electromagnetic fields: Critical evaluation of behavioral and neurophysiological studies. And many studies related to cell phones were funded by organizations that have a vested interest in promoting cell phone use. Some cell phone users have reported blurred vision, difficulty concentrating and tinnitus (ringing in the ears).
Overall, the trend shows no major impact (note: many of the tests used in the studies were very simple). The further the cell phone is away from your body, the less exposure you have to the radiofrequency (another benefit of texting).
As you might imagine, they don’t quite measure up to the radiofrequency safety standards model.
One study in mice found that low amounts of radiation from cell phones might actually help to fight off Alzheimer’s disease (the study has been criticized by experts). Riverbeds must be cleared, toxic waste is generated, and mining zones include areas that are home to gorillas (gorilla populations in Congo have decreased by 90% in the last several years).
