If you’re thinking of buying a phone case with ‘radiation blocking material’ believing it will reduce radiation, you should know this: Phones have automatic power control, such cases act as shields and make the phone work harder, transmitting more power, increasing heat and reducing battery life, The incoming signal to the phone will also be reduced so your phone may not work in areas of poor signal.
“In addition to protecting your phone from scratches and breaks, a basic case can help conceal a distinctive phone’s telltale markings. That’s a detriment if you’re trying to show off your handset’s badass styling, but a benefit for maintaining a lower profile. Note: Even though they look better, a flashy designer case is like sticking a “steal me” marquee on your phone.” – Jessica Dolcourt, Keep Your Phone from Getting Stolen (and What to Do If It Is), CNET; Twitter: @CNET

The 5.93-inch screen is massive, with plenty of room for most games and movies. The Kirin 659 processor is powerful and capable of standing with any other similarly priced phone on the market. The 3,340mAh battery is long-lasting, and kids who like to take snaps (most kids have an Instagram game that’s on point) will appreciate the extremely good dual-sensor camera suite on the back of the phone. The metal unibody is strong and should be fairly durable, and since it’s running Android there are tons of great parental control apps out there. The only real downside is that Honor’s phones do not support Verizon or Sprint, so if you’re on a family plan with either of those two, this isn’t your best choice. Otherwise, the Honor 7X is a fantastic budget smartphone that kids will love.
In subsequent analyses of Interphone data, investigators addressed issues of risk according to specific location of the tumor and estimated exposures. One analysis of data from seven of the countries in the Interphone study found no relationship between brain tumor location and regions of the brain that were exposed to the highest level of radiofrequency radiation from cell phones (9). However, another study, using data from five of the countries, reported suggestions of an increased risk of glioma and, to a lesser extent, of meningioma developing in areas of the brain experiencing the highest exposure (10).
In response to public concern, the WHO established the International EMF Project in 1996 to assess the scientific evidence of possible health effects of EMF in the frequency range from 0 to 300 GHz. They have stated that although extensive research has been conducted into possible health effects of exposure to many parts of the frequency spectrum, all reviews conducted so far have indicated that, as long as exposures are below the limits recommended in the ICNIRP (1998) EMF guidelines, which cover the full frequency range from 0–300 GHz, such exposures do not produce any known adverse health effect. Stronger or more frequent exposures to EMF can be unhealthy, and in fact serve as the basis for electromagnetic weaponry.
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.

When Carlo arrived, he was met by two seriously muscled men in plain clothes; the larger of the two let drop that he had recently left the Secret Service. The security men steered Carlo into a holding room, where they insisted he remain until his presentation. When summoned, Carlo found roughly 70 of the industry’s top executives waiting for him in silence. Carlo had spoken a mere 10 minutes when Wheeler abruptly stood, extended a hand, and said, “Thank you, George.” The two muscle men then ushered the scientist to a curbside taxi and waited until it pulled away.13
The Federal Communications Commission (FCC),  US Government Accountability Office (GAO),  and the US Food and Drug Administration (FDA),  have all concluded that there is no evidence in the scientific literature proving that cell phones cause brain tumors or other health problems. According to the FDA, "attempts to replicate and confirm the few studies that did show a connection [between cell phone radiation and head tumors] have failed."

Enter: Radiation. Lots of radiation. According to some research studies, there’s enough EMF radiation emitted by our cell phones to penetrate two inches into the adult brain, and all cell phones hazardously heat our biological tissue, wreaking havoc on many parts of our body. Which leads to serious health issues like fatigue, headaches, brain tumors, DNA alteration, impaired immune system, damaged brain activity and a variety of cancers. At least, that’s what we know now.
It is useful to be aware of new health research regarding cell phone usage and cell phone radiation. The first cell phone call was made in 1985 and that phone cost $5,000 and weighed about 9 pounds. The change in size, weight and cost of devices today has probably led to over 50% of the human race owning a mobile device, the fastest growing technology on the planet.
