We couldn't find one legit EMF expert online or anywhere else that would recommend a radiation blocking case or anti-radiation case. Not the Environmental Health Trust or Magda Havas, or Joel Moskowitz, in fact his site, safeEMR cautions against scams and claims for radiation protection.  So if a so-called "EMF expert" is recommending any kind of anti-radiation case, they probably aren't that much of an expert. 
Cellsafe have developed revolutionary NEW Smart Radi-Chip technology, giving you the freedom to use any protective phone / iPad case or to enjoy your device without a case while reducing radiation absorption by up to 95%* (* refer to test results page for individual results according to phone make & frequency band). This product is micro-thin (0.35mm) adhesive chip which attaches to the back of the phone / iPad and can be used with any mobile phone / iPad case fitted over the top. Suitable for most popular Smart Phones & iPads. Cellsafe’s groundbreaking technology is NOT a shield and will not interfere with transmission signal or with call reception.
Also, every inch you put between yourself and your Wi-Fi router significantly lowers the strength of the radiation your body encounters. “Put it this way,” Foster says. “During a call, your mobile phone is transmitting steadily at a strength maybe 100 times more powerful than Wi-Fi, and you’re holding the phone right against your head, and we still don’t find any health issues with that level of exposure.”
W. Kim Johnson, a retired physicist and past president of the New Mexico Academy of Science, reviewed the Aires web site for Discovery News and described the material as gibberish, saying that the authors "of the technical description of the ‘Aires' device reads like a random selection of technical terminology. The working description for this device is made up of jargon that, in the end, really says nothing."

The FCC provides information about the specific absorption rate (SAR) of cell phones produced and marketed within the last 1 to 2 years. The SAR corresponds with the relative amount of radiofrequency radiation absorbed by the head of a cell phone user (47). Consumers can access this information using the phone’s FCC ID number, which is usually located on the case of the phone, and the FCC’s ID search form.
Repeated Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload. Each of these effects are also caused by exposures to other microwave frequency EMFs, with each such effect being documented in from 10 to 16 reviews. Therefore, each of these seven EMF effects are established effects of Wi-Fi and of other microwave frequency EMFs. Each of these seven is also produced by downstream effects of the main action of such EMFs, voltage-gated calcium channel (VGCC) activation. While VGCC activation via EMF interaction with the VGCC voltage sensor seems to be the predominant mechanism of action of EMFs, other mechanisms appear to have minor roles. Minor roles include activation of other voltage-gated ion channels, calcium cyclotron resonance and the geomagnetic magnetoreception mechanism. 
You can actually get a completely mechanical timer on Amazon for super cheap. Then all you have to do is plug your router into it, and set a time period, say from midnight to 7 am, and it will automatically turn your router off and then back on again. Depending on your sensitivity to EMF radiation, you could quickly notice better and more restful sleep.

TRPV1 cation channels are the possible molecular pathways responsible for changes in the hormone, oxidative stress, and body temperature levels in the uterus of maternal rats following a year-long exposure to electromagnetic radiation exposure from mobile phones and Wi-Fi devices. It is likely that TRPV1-mediated Ca2+ entry in the uterus of pregnant rats involves accumulation of oxidative stress and opening of mitochondrial membrane pores that consequently leads to mitochondrial dysfunction, substantial swelling of the mitochondria with rupture of the outer membrane and release of oxidants such as superoxide (O2 −) and hydrogen peroxide (H2O2). The superoxide radical is converted to H2O2 by superoxide dismutase (SOD) enzyme. Glutathione peroxidase (GSH-Px) is an important antioxidant enzyme for removing lipid hydroperoxides and hydrogen peroxide and it catalyzes the reduction of H2O2 to water.
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
Depends on if you have other sources present in your home as well. Cordless home phone+base station, Smart Meter, Non-eco Wifi-Router (Eco will reduce the 10 pulses to 1 pulse per second on your Router, even when it has no connected devices.) An ethernetcable will work great, but make sure to disable the active wifi connection on your Laptop or Pc.
The objective of this study was to evaluate the effects of radiofrequency radiation emitted from an internet-connected laptop via Wi-Fi for 4 hours on human sperm motility, viability, and DNA fragmentation. Donor sperm samples, mostly normozoospermic, exposed to a wireless internet-connected laptop showed a significant decrease in progressive sperm motility and an increase in sperm DNA fragmentation. We speculate that keeping a laptop connected wirelessly to the internet on the lap near the testes may result in decreased male fertility.
This argument implies that the safest legislation totally bans use of cell phones in cars. This platform faces steep opposition from telecommunications lobbyists and auto manufacturers. If everyone on the road right now were unable to dial into his or her cell phones, life would be vastly different. Business transactions would slow and wireless providers would lose millions of dollars. But maybe, just maybe, auto accidents would drop drastically.
The wireless communications industry is rushing to blanket the nation with next-generation networks whose health effects are unknown. Despite studies linking radiation from existing networks to cancer in lab animals, the Federal Communications Commission and state legislators are bowing to industry lobbyists and clearing the way for the new networks.  
ShieldMe  On the ShieldMe site is a message from Wireless Connection CEO Rose Vitale addressing issues with the cellphone industry and she makes some good points.  As far as how ShieldMe works she states, " Our ShieldMe cases help deflect up to 99% of the harmful EMF, RF or microwave radiation emitted from a cellphone while carrying around or when on a call." The demonstration of the SheildMe case shows levels that like the "EMF protection cellphone cases" is many many times higher than levels EMF expert Larry Gust follows as a certified building biologist.

But this was not the message that media coverage of the NTP study conveyed, as the industry blanketed reporters with its usual “more research is needed” spin. “Seriously, stop with the irresponsible reporting on cell phones and cancer,” demanded a Vox headline. “Don’t Believe the Hype,” urged The Washington Post. Newsweek, for its part, stated the NTP’s findings in a single paragraph, then devoted the rest of the article to an argument for why they should be ignored.49
But meanwhile know for certain that research is confirming that exposure to ICRW or Information Carrying Radio Waves, also called   wireless energy, can do all kinds of things from compromising immunity and causing the body to react by forming tumors to creating symptoms like headaches, trouble sleeping, anxiety and ringing in the ears. Other common sources of this same type of "non-ionizing radiation" include: cell phones, baby monitors, and computers and Smart Meters. Studies of symptoms from exposure to RF microwave(yes this EMF energy goes by many titles!) include heart racing, tingling sensations, numbness, dizziness, and fatigue. 
METHODS: Standard class V cavities were prepared on the buccal surfaces of 20 non-carious extracted human premolars. The teeth were randomly divided into 2 groups (n = 10). The control group was stored in non-environment. The specimens in the experimental groups were exposed to a radiofrequency radiation emitted from standard Wi Fi devices at 2.4 GHz for 20 min. The distance between the Wi-Fi router and samples was 30 cm and the router was exchanging data with a laptop computer that was placed 20 m away from the router. The concentration of mercury in the artificial saliva in the groups was evaluated by using a cold-vapor atomic absorption Mercury Analyzer System. The independent t test was used to evaluate any significant differences in mercury release between the two groups.
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
“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
