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. 
The purpose of this study was to investigate the effects of low level electromagnetic field (low level-EMF) exposure, as frequently encountered in daily life (2.45 GHz, 2h/day for 21 days), on the normal adult male rat cornea using histological and stereological method. There was no statistically significant difference in mean corneal thicknesses between the groups (p > 0.05), however there were statistically differences between the groups with regard to the thickness of anterior epithelium (p < 0.05). Results of this preliminary study show that exposure to MW radiation might cause alterations in the rat cornea.
Microwave irradiation resulted in thinner cell walls, smaller chloroplasts and mitochondria, and enhanced emissions of volatile compounds, in particular, monoterpenes and green leaf volatiles (GLV). These effects were stronger for WLAN-frequency microwaves. Essential oil content was enhanced by GSM-frequency microwaves, but the effect of WLAN-frequency microwaves was inhibitory. There was a direct relationship between microwave-induced structural and chemical modifications of the three plant species studied.
There are theoretical considerations as to why the possible risk should be investigated separately in children. Their nervous systems are still developing and, therefore, more vulnerable to factors that may cause cancer. Their heads are smaller than those of adults and consequently have a greater proportional exposure to the field of radiofrequency radiation that is emitted by cell phones. And, children have the potential of accumulating more years of cell phone exposure than adults do.

Many wireless routers automatically kick wifi back on when there is a firmware update, or the device gets restarted. When our internet is running slow or not working, the first thing our internet provider will tell us to do is power cycle the router and modem (basically just turning them both off and back on). Make sure that when your router comes back on it doesn’t automatically turn the wifi back on.
Consider parental-control tools. There are actually two major types of parental controls. The first is family rules or guidelines that you establish with your children, and the second is technology tools provided by cellphone companies, smartphone makers and app developers. If you do use technology to monitor or limit your child’s phone activities, in most cases it’s a good idea to be up front with them and revisit it every now and then as they mature.

We’ve rounded up 50 valuable tips from experts on mobile devices, wireless, safe Internet usage, and more to help you get the most from your cell phone. Play it safe by using your device when it’s safe to do so, avoiding calls and texts from anonymous numbers to steer clear of phishing and other scams, learn strategies for monitoring your kids’ cell phone use to stay on top of potential problems, and teach your kids about smart mobile usage.
Numerous peer-reviewed studies have shown an association between cell phone use and the development of brain tumors. According to a Mar. 2008 meta-analysis of cell phone studies there is a "consistent pattern" connecting cell phone use and an increased risk of developing glioma, a type of brain tumor. [12] A Mar. 31, 2009 study found that long term cell phone use (10 years +) "approximately doubles the risk" of being diagnosed with glioma on the same side of the head where the cell phone is held. [51] In Apr. 2013 another study of Swedish cell phone users also found an association between cell phone use and the development of glioma and acoustic neuroma - a benign tumor formation on the nerve near the ear. [52] That study’s conclusions were confirmed by a different study in Apr. 2014. [84] Other studies published from 2005-2013 have similarly concluded that there is an association between cell phone use and increased risk of developing brain and head tumors. [13] [53] [54] [55]
I think it might be part of the problem with all these kids losing it in the last decade and a half. Just something to think about. Maybe they should start building “wifi free”restaurants and buildings. They have been warning people since before they even started using it on a commercial bases that wifi was going to have serious effects on the human body. There’s just so much of a “hey as long as it doesn’t bother me I don’t care” attitude. I mean think about it. Now I’m not saying this in a negative way but look at the turnaround in public opinion about gay marriage. I mean it went from a hotly debated topic to “ah well they ain’t hurting anybody so let them do what they want. Except in the red states and if you notice a lot of those states are lacking saturated wifi signals. Just something to think about
Changing technology and methods of use. Older studies evaluated radiofrequency radiation exposure from analog cell phones. Today, cell phones use digital technology, which operates at a different frequency and a lower power level than analog phones. Digital cell phones have been in use for more than two decades in the United States, and cellular technology continues to change (3). Texting and other applications, for example, are common uses of cell phones that do not require bringing the phone close to the head. Furthermore, the use of hands-free technology, such as wired and wireless headsets, is increasing and may reduce exposure by distancing the phone from the body (36, 37).
Dr. Carlo, wrote a  Medical Alert ten years ago. He cautioned people with EMF sensitivity against relying upon widely-available EMR Protection Products to prevent the effects of EMF exposure. He noted that EMF sensitive individuals were reporting the opposite effect: people found their symptoms and/or sensitivity worsened. Specifically, severe “symptom relapses.” Dr. Carlo noted:
The present study aimed to investigate the effects of chronic low-intensity microwave exposure (900, 1800 or 2450 MHz for 180 days) on cognitive function, heat shock protein 70 (HSP70), and DNA damage in the rat brain. The results showed declined cognitive function, elevated HSP70 level, and DNA damage in the brain of microwave-exposed animals. The results indicated that, chronic low-intensity microwave exposure in the frequency range of 900 to 2450 MHz may cause hazardous effects on the brain.
Since they're hybrids of the two accessories you generally carry, there's obviously less room for your stuff. However, most guys — when push comes to shove — can get by with just a few frequently used credit cards and IDs. We're sharing seven of our favorite wallet cases for you to take a look at, below. If space is too big of a compromise here, but you still want something that's on the slim side, there are always card cases to consider.
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.”
