Moving the meter around the case, we detect readings on the side, back and front of the case. We use the multi-directional TES 593 meter which measures 10 MHz to 8GHz. We use the unit of micro-watts per square centimeter, which looks like this little symbol: μW/cm² and we use it on the max setting which shows the maximum measured value. In non-science speak: the highest level of RF we see, which could be from the back the side or the front.
An Oct. 20, 2011 study of 358,403 Danish citizens – the largest study of its kind to date – concluded that "there was no association between tumors of the central nervous system or brain and long term (10 years +) use of mobile phones."  A July 27, 2011 study found that there was no association between cell phone use and brain tumor risks among children and adolescents.  Numerous other studies published from 2001-2013 have similarly concluded that there is no association between cell phone use and the development of brain tumors.      
It’s been suggested that sleeping near a phone, in a home with Wi-Fi, or in an apartment building with many Wi-Fi signals can create chronic sleep problems as the constant bombardment of Wi-Fi pollution interferes with falling asleep and sleep patterns. For many, sleep deprivation is just the start for larger problems. The development of depression and hypertension have also been linked to inadequate sleep. 
38. Does your child need that phone feature? Parental control apps allow parents to exert greater control over the features and functions their children can access on their smartphones. Making use of these apps and other tools to restrict access to the features you deem safe and appropriate can go a long way in keeping your kids safe while giving you much-needed peace of mind. “Determine what features your child needs based on his age. Does your 10-year-old really need web browsing capabilities?” – Laura Willard, Cell Phone Safety Tips for Kids, Tweens and Teens, SheKnows; Twitter: @SheKnows
Joel Moskowitz (@berkeleyprc) of the University of California, Berkeley School of Public Health, US, says: “This is the largest technological experiment in the history of our species, with potential health risks we still know next to nothing about.” This view is shared by Denis Henshaw, professor of human radiation effects at Bristol University, UK, who said: “Vast numbers of people are using cell phones and this could be a time bomb of health problems.”
