Exposure to ionizing radiation, such as from x-rays, is known to increase the risk of cancer. However, although many studies have examined the potential health effects of non-ionizing radiation from radar, microwave ovens, cell phones, and other sources, there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans (2).
The very next day, a livid Tom Wheeler began publicly trashing Carlo to the media. In a letter he shared with the CEOs, Wheeler told Carlo that the CTIA was “certain that you have never provided CTIA with the studies you mention”—an apparent effort to shield the industry from liability in the lawsuits that had led to Carlo’s hiring in the first place. Wheeler charged further that the studies had not been published in peer-reviewed journals, casting doubt on their validity.10
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.
gamma rays are constantly going through you as we speak as are wifi. that doesn’t mean however that you can create much usable electricity from them. you cannot. because the amount of energy inherent in these is miniscule. actually for somebody making judgements about what other people may or may not be you seem to be very ignorant about basic facts.
40. Set clear rules and guidelines for downloading media and apps. Giving your kids free reign to use all the features on their smartphones can quickly rack up your wireless bill and introduce security risks to their devices. “Downloading new ringtones or games can add unwanted expenses or hidden bugs. Set limits and rules about downloads.” – Amanda Martin, Cell Phone Safety Tips for your Child, Securemama.com; Twitter: @securemama
You are being trolled people. This article is so obviously not correct. All of the examples given are so subjective and there are hints in there that they are having a laugh at you for believing this. “When a group of Danish ninth graders experienced difficulty concentrating after sleeping” Come on, really? It wasn’t because they were playing games or chatting to their friends that their minds were too stimulated to sleep straight away?
Prenatal exposure to radiation from cell phones may increase the risk of ADHD and other behavior problems in children. According to a peer-reviewed Nov. 2008 study in the journal Epidemiology, exposure to cell phone radiation while in the womb "was associated with behavior difficulties such as emotional and hyperactivity problems around the age of school entry."  A Dec. 2010 study replicated those findings.  A peer-reviewed Mar. 15, 2012 study found that mice exposed to cell phone radiation in the womb "were hyperactive and had impaired memory" as adults. 
45. Keep it organized. “Always keep your child’s cell phone charger in the same place. It’s best to find a central location — like maybe the kitchen counter, or a table by the door. Mark the end of the monthly billing cycle on a calendar to remind her how long those dwindling minutes have to last.” – Fayette Woman, 10 Cell Phone Safety Tips for Parents, Fayette Woman; Twitter: @faywoman
There is no clearly-defined safe distance as this new issue has yet been studied enough. While EMF emissions from different routers vary, for most home WiFi routers, a distance of 40 feet (ideally, or 10 feet at a minimum) will help your body and shouldn’t impact your WiFi connection too much. And beware that radiation from WiFi routers can pass through the walls in your home so keep this in mind as you evaluate the safety of your bed's location. Those who are sensitive to EMFs should take extra efforts to reduce EMFs and chronic proximity to the sources.
A 2005 study in the International Journal of Cardiology found that mobile phones may have "adverse effects" on pacemaker functions under certain conditions.  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.  The American Heart Association includes cell phones on its list of "devices that may interfere with pacemakers."
