The present study investigated the influence of 2.4GHz electromagnetic fields, similar to that emitted by Wi-Fi system, on human brain activity. The presence of radiation had no effect on the energies of alpha and beta band of male subjects, while it reduced these energies of female subjects, resulting in significantly lower energies, as compared to those of males. Delta and theta band energies did not experience any noteworthy effect from gender, radiation condition and their interaction. Conversely, there was a significant interaction effect (gender x radiation) on the energies of alpha and beta rhythms. The present data support the idea that Wi-Fi signal may influence normal physiology through changes in gender related cortical excitability, as reflected by alpha and beta EEG frequencies.
The International Agency for Research on Cancer (IARC) has classified cell phone radiation as a possible carcinogen. On May 31, 2011, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) issued a press release announcing it had added cell phone radiation to its list of physical agents that are "possibly carcinogenic to humans" (group 2B agents).  The classification was made after a working group of 31 scientists completed a review of previously published studies and found "limited evidence of carcinogenicity" from the radiofrequency electromagnetic fields emitted by wireless phones, radio, television, and radar. 
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.
This study investigated the effect of 2.45 GHz microwave radiation (2 h/day for 45 days) on biomarkers within Wistar rats. A significant decrease (P < 0.05) was recorded in the level of pineal melatonin of exposed group as compared with sham exposed, while a significant increase (P < 0.05) in creatine kinase, caspase 3, and calcium ion concentration was observed in whole brain of exposed group of animals as compared to sham exposed. The study concludes that a reduction in melatonin or an increase in caspase-3, creatine kinase, and calcium ion may cause significant damage in brain due to chronic exposure of these radiations. These biomarkers clearly indicate possible health implications of such exposures.

43. Search for the unknown callers. Discovering unknown or anonymous numbers on your child’s phone can be alarming, but a bit of detective work can lead you to answers. “Now that you know who your kid chats with, you can see if there are any messages that make you suspicious. If you spot a phone number you don’t recognize, do a reverse phone lookup to discover exactly who they are talking to. By searching any domestic number, you may discover the texter’s name, carrier, and address.
While that’s all scary as heck, I think it’s everything we don’t know about EMF exposure that scares me the most. That, and how seldom EMFs are discussed. If it hadn’t been for my dear friend August Brice, a Tech Wellness Advocate, I don’t think I would have ever considered the safety hazards associated with everyday cell phone use. Or had any knowledge of the subject whatsoever. Let’s be real, this topic has certainly never appeared in the trending tab on Twitter, and I’ve yet to see it spark a viral video.
Of course they’re not. But they are banning wireless communication in nursery schools, because that’s new and parents aren’t entirely sure about what makes it work. Parents are, quite rightly, very worried about how any new thing will affect their children. Some things, like the effect of texting using proper grammar or how more screen time affects attention spans, are difficult to measure and we don’t really know how people will be when they grow up. But Wi-Fi as a cause of cancer or even headaches? We can test for that. We have tested for that. It’s fine.
46. Tape your home number on your phone (or a parent’s cell phone number). “Imagine your child’s phone (or your own) is lost. Even if the person who finds it wants to return it, they have to go through your private information to find a number to dial. Make it easy. Tape your home number (or whatever number is suitable) to the back of the phone, along with information about a reward, if you like. That way, even with a password locking the keypad or screen, a do-gooder can get you your phone back!” – marianmerritt, Cell Phone Safety Tips for Kids, Norton Community by Symantec; Twitter: @NortonSupport
The scientific evidence that cell phones and wireless technologies in general can cause cancer and genetic damage is not definitive, but it is abundant and has been increasing over time. Contrary to the impression that most news coverage has given the public, 90 percent of the 200 existing studies included in the National Institutes of Health’s PubMed database on the oxidative effects of wireless radiation—its tendency to cause cells to shed electrons, which can lead to cancer and other diseases—have found a significant impact, according to a survey of the scientific literature conducted by Henry Lai. Seventy-two percent of neurological studies and 64 percent of DNA studies have also found effects.52

2. The power, or heating effect, of the phone is only one of many possible factors impacting cell phone ‘safety.’ Certainly it is useful to know if your phone has a high SAR value, but exposures to the radiation from the cell phone at non-heating levels have been linked to many serious biological effects, and the SAR value is not capturing anything about these harmful non-thermal exposures.
35. Check your child’s cell phone records. “Review cell phone records for any unknown numbers and late night phone calls and texts.” While it may feel as though you’re snooping on your kids, reviewing their calling and texting records can help you identify warning signs such as strange calling patterns or unfamiliar numbers that could indicate that your child is communicating with someone they shouldn’t be such as a potential predator. – Help children use cell phones safely, NetSmartz Workshop; Twitter: @NetSmartz
To be sure, the industry could not have been pleased with some of the Interphone study’s conclusions. The study found that the heaviest cell-phone users were 80 percent more likely to develop glioma. (The initial finding of 40 percent was increased to 80 to correct for selection bias.) The Interphone study also concluded that individuals who had owned a cell phone for 10 years or longer saw their risk of glioma increase by nearly 120 percent. However, the study did not find any increased risk for individuals who used their cell phones less frequently; nor was there evidence of any connection with meningioma.36
Since the development of communication devices and expansion of their applications, there have been concerns about their harmful health effects. The main aim of this study was to investigate laptop thermal effects caused by exposure to electromagnetic fields and thermal sources simultaneously; propose a nondestructive, replicable process that is less expensive than clinical measurements; and to study the effects of positioning any new device near the human body in steady state conditions to ensure safety by U.S. and European standard thresholds. A computer simulation was designed to obtain laptop heat flux from SolidWorks flow simulation. Increase in body temperature due to heat flux was calculated, and antenna radiation was calculated using Computer Simulation Technology (CST) Microwave Studio software. Steady state temperature and specific absorption rate (SAR) distribution in user's body, and heat flux beneath the laptop, were obtained from simulations. The laptop in its high performance mode caused 420 (W/m2 ) peak two-dimensional heat flux beneath it. The cumulative effect of laptop in high performance mode and 1 W antenna radiation resulted in temperatures of 42.9, 38.1, and 37.2 °C in lap skin, scrotum, and testis, that is, 5.6, 2.1, and 1.4 °C increase in temperature, respectively. Also, 1 W antenna radiation caused 0.37 × 10-3 and 0.13 × 10-1.
Since we have this subconscious, ever-present fear of death, we employ magical thinking to give us a false sense of power over it. When we create artificial threats to our survival in our imagination, and then avoid practicing behaviors that make us vulnerable to those threats, we feel we have some power over whether we live or die. These are also known as superstitions.
No, it isn’t. It is true that International Agency for Research on Cancer (part of the World Health Organisation) has classified radiofrequency electromagnetic fields, including radiofrequency electromagnetic fields from wireless phones as ‘2b’ in its monographs on the evaluation of carcinogenic risks to humans. But that’s by no means proof of danger. You see 2b is ‘possibly carcinogenic’ and as well as Wi-Fi, the category includes coffee, carpentry and pickled vegetables. Some evidence has to be present (except when insufficient evidence is accepted) but the case does not have to be proven.
No scientist can say with certainty how many wireless-technology users are likely to contract cancer, but that is precisely the point: We simply don’t know. Nevertheless, we are proceeding as if we do know the risk, and that the risk is vanishingly small. Meanwhile, more and more people around the world, including countless children and adolescents, are getting addicted to cell phones every day, and the shift to radiation-heavy 5G technology is regarded as a fait accompli. Which is just how Big Wireless likes it.55
Wifi does affect your health and well being. I put up a wifi router nearby a couple of bee hives in different places. The bees left the hives. I removed the wifi router, the bees gradually returned; I see how arrogant and stupid the population has turned. Cattle, simple cattle. as Osiah in old testmanent states ” Father, my people lack knowledge”…. this applies today to all subjects
Based on our results, it can be concluded that the bacterial strains used in this study respond differently to EMFs. These bacteria were capable of responding to environmental stresses that act by activating some specific systems such as ion channels, change via the membrane, DNA repair system, and probably ion efflux pumps in the membrane as well as interactions of molecules and antibacterial agents. There are some ambiguities that need further investigations regarding answering questions such as which cellular mechanism is responsible for adaptation? Which factors are involved in alterations of antibacterial sensitivity? And subsequently, what are the differences in the response to radiation in gram-negative and gram-positive bacteria? Moreover, experiments on different bacterial strains with various electromagnetic fields should be performed in the future to better clarify these uncertainties.
