Anti-radiation or radiation blocking or phone shield cases. Do they Work? SafeSleeve, DefenderShield, Vest, Alara, Pong, Reach and ShieldMe  and other EMF protection phone cases claim to block the radiation from your cellphone or smartphone. Anti-radiation cellphone case brands make enticing claims like this: ". . .eliminate up to 99% of the harmful radiation coming from the phone!"
We’re living in a wireless technology age, but there’s some evidence that exposure to electromagnetic radiation from cell phones and wireless devices could increase your risk of certain cancers and tumors. However, more research is needed. In the meantime, I recommend practicing the precautionary principle. Some great cell phone safety tips include:
you really are stuck with “electricity”. How much electricity do gamma rays produce in human body yet so damaging to human and animal tissues because of their high level of energy. it seems any discussion with you is a waste of time considering your demonstrably shaky fundamentals of physics. you appear to be a very good technician rather than physicist of any kind.
Merely injecting us with vaccines and their toxic metals is one thing. Then EMF out there is another. However, putting the two together, what do we have? Now let’s look at the push to increased the saturation in the environment with cell towers in and around school grounds with mandatory vaccinations for kids. Makes you wonder. The general population is encourage to get vaccines while SmartMeters, the ubiquity of WiFi and cell phones surround us.
This study aimed to examine the therapeutic effects of a 100 Hz pulsed electromagnetic field (2 h/day for 60 days) on the reproductive systems of male Wistar rats (70 days old).The results showed significant increases in caspase and creatine kinase and significant decreases in testosterone and melatonin in the exposed groups. This finding emphasizes that reactive oxygen species (a potential inducer of cancer) are the primary cause of DNA damage. However, pulsed electromagnetic field exposure relieves the effect of microwave exposure by inducing Faraday currents.
These experimental findings raise new questions as to the potential for radiofrequency radiation to result in cellular changes and offer potential avenues for further laboratory studies. Cancers in the heart are extremely rare in humans, where the primary outcomes of potential concern with respect to radiofrequency radiation exposure from cell phones are tumors in the brain and central nervous system. Schwann cells of the heart in rodents are similar to the kind of cells in humans that give rise to acoustic neuromas (also known as vestibular schwannomas), which some studies have suggested are increased in people who reported the heaviest use of cell phones. The NTP has stated that they will continue to study this exposure in animal models to further advance our understanding of the biological underpinnings of the effects reported above.
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
The revolving-door syndrome that characterizes so many industries and federal agencies reinforces the close relationship between the wireless industry and the FCC. Just as Tom Wheeler went from running the CTIA (1992– 2004) to chairing the FCC (2013–2017), Meredith Atwell Baker went from FCC commissioner (2009–2011) to the presidency of the CTIA (2014 through today). To ensure its access on Capitol Hill, the wireless industry made $26 million in campaign contributions in 2016, according to the Center for Responsive Politics, and spent $87 million on lobbying in 2017.32
Turn Off WiFi Before Bed: This is one of our favorites in our Tech Wellness Top 10 easy ways to make wireless safer: We call it our Wi-Fi Kill-switch so you don't have to get close the Router. It's as important as WiFi Router placement. The simple step of hitting the off switch can lead to a better night’s sleep. Or, try this timer that can shut or kill that nasty Wifi energy any time of day or night. When on, a WiFi signal may interfere with our brains during sleep, so by turning it off we reduce exposure and hopefully rest more deeply.
Outside critics soon came to suspect that Carlo would be the front man for an industry whitewash. They cited his dispute with Henry Lai, a professor of biochemistry at the University of Washington, over a study that Lai had conducted examining whether cell-phone radiation could damage DNA. In 1999, Carlo and the WTR’s general counsel sent a letter to the university’s president urging that Lai be fired for his alleged violation of research protocols. Lai accused the WTR of tampering with his experiment’s results. Both Carlo and Lai deny the other’s accusations.5
AAP also advocates for more research into the human health impacts of cell phone radiation, particularly when it comes to children. One current problem? Federal Communications Commission tests used to determine cell phone radiation is based on the devices’ possible effect on large adults — not kids. Children’s skulls are thinner and can absorb more radiation (4)
We investigated the long-term effects of radiofrequency radiation (RFR) emitted from Wi-Fi systems on hearing. Sixteen Wistar albino rats were divided equally into two groups: sham control and exposure groups. The rats in the experimental group were exposed to 2.4 GHz RFR emitted from a Wi-Fi generator for 24 h/day for one year. The same procedure was applied to the rats in the sham group, except that the Wi-Fi generator was turned off. All groups were kept in Faraday cages during the 12 months to eliminate external electromagnetic fields. The distance between the Wi-Fi generator antenna and the exposure cages was 50 cm. Pre-exposure distortion product otoacoustic emissions (DPOAE) of all rats were measured at the beginning, 6th and 12th months of the study. The DPOAE values of the sham, baseline and exposure groups were compared statistically. For the 6000 Hz hearing frequency, the DPOAE values in the exposure group were lower than those in the sham group (p < 0.05). Similarly, the 6000 Hz hearing frequency values obtained at the end of the 12th month were also lower than the baseline and 6-month values in the exposure group (p < 0.05). In contrast, the DPOAE values at the 6th and 12th months of exposure for the 2000 Hz hearing frequency were higher than the baseline value (p < 0.05). These results indicated that 12 months of RFR (24 h/day) at 50 cm from a 2.4 GHz Wi-Fi source can affect hearing. However, further studies are necessary.

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
“There are 25,000 brain tumor cases in India’s Andhra Pradesh and Telangana states, and most of them are attributed to excessive use of cell phones, as per a recent medical survey”. Girish Kumar said that World Health Organization warned of increasing risk of cell phone brain tumor and cancer cases caused by the use of cell phones and location of cell towers in residential areas.
