When it comes to cell phones, scientists have looked at findings from animal research and cells in test tubes exposed to RF radiation in a lab, as well as observational studies in humans. These human studies have tried to see whether heavy users of cell phones have higher rates of brain cancers and other health problems compared with people who use cell phones less often.
If you’re a family that typically opts for Apple devices, you can share your iTunes content and easily keep track of your child’s location. It certainly isn’t the cheapest smartphone you could buy for your child, but it has great specs, terrific software, and it’s a manageable size for smaller hands. If mom and dad have iPhones already, it’s definitely the most convenient choice. Check out our full review for more information.
The present study determined the effects of prenatal and postnatal exposure to 2.45 GHz Wi-Fi-induced electromagnetic radiation (2h/day for 21 days during pregnancy and 21 days during lactation) on tooth and surrounding tissue development as well as the element levels in growing rats. Histological and immunohistochemical examinations between the experimental and control groups showed that exposure to 2.45 GHz EMR for 2 h per day does not interfere with the development of teeth and surrounding tissues. However, there were alterations in the elemental composition of the teeth, especially affecting such oxidative stress-related elements as copper, zinc, and iron, suggesting that short-term exposure to Wi-Fi-induced EMR may cause an imbalance in the oxidative stress condition in the teeth of growing rats.
20. Remember to focus on driving. “Don’t look up phone numbers, don’t take notes or play with your PDA (personal digital assistant) while driving. These activities prohibit you from watching where you are going. Of course, you shouldn’t read the paper, apply eye make-up or write notes while driving either! Driving is serious business.” – How to Hear in a Hands-Free World: Mobile and Cell Phone Safety Tips, AudiologyOnline; Twitter: @audiologyonline
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. 
Ionizing radiation, including x-rays and ultraviolet light, produces molecules called ions that have either too many or too few electrons. Ions are known to damage DNA and cause cancer. Cell phone radiation, like radio, TV, and visible light radiation, is non-ionizing and lacks sufficient energy to add or remove electrons from molecules, and therefore it cannot ionize and cause cancer.  According to the authors of a 2005 peer-reviewed study of 3.7 million Swedish residents, a "biologic mechanism that could explain any possible carcinogenic effect from radiofrequency radiation has not been identified." 
Have you ever felt more awake after using Wi-Fi or even struggled to sleep through the night? Reports of these phenomena have been frequent and even prompted a study in 2007 that evaluated low-frequency modulation from cell phones and its impact on sleep. Participants were exposed to the electromagnetic signals from real phones or no signal from fake phones. Those exposed to the electromagnetic radiation had a significantly more difficult time falling asleep and changes in brainwave patterns were observed.

Studies by five independent research groups regarding cell phones and brain tumors have revealed significantly increased risks of a benign tumour of the cranial nerve supplying the ear. This grows slowly and must be removed in a major operation that can result in permanent facial paralysis. Other risks found were cancer of the glial cells (including neurons) of the nervous system and cancer of the meninges, the membrane covering the brain and spinal cord.
