We really do not recommend any kind of chip, guard, anti-radiation "filters" or incomplete shielding case because honestly, how could they NOT provide a false sense of security? Folks could believe these products make them “invincible” against radiation so they are comfortable holding the case right up to their heads-and the radiation seeping from the back and the side of the phone case is in very close proximity to their precious brains. Oh no!

Exposure to non-thermal radio frequency radiation from Wi-Fi and cellular phones can disrupt normal cellular development, especially fetal development. A 2004 animal study linked exposure to delayed kidney development. [4] These findings were supported by a 2009 Austrian study. In fact, the disruption of protein synthesis is so severe that authors specifically noted, “this cell property is especially pronounced in growing tissues, that is, in children and youth. Consequently, these population groups would be more susceptible than average to the described effects.” [5] In short, bathing the developmentally young in Wi-Fi increases their risk of developmental issues.

There is no clearly-defined safe distance as this new issue has yet been studied enough. While EMF emissions from different routers vary, for most home WiFi routers, a distance of 40 feet (ideally, or 10 feet at a minimum) will help your body and shouldn’t impact your WiFi connection too much. And beware that radiation from WiFi routers can pass through the walls in your home so keep this in mind as you evaluate the safety of your bed's location. Those who are sensitive to EMFs should take extra efforts to reduce EMFs and chronic proximity to the sources.
In the years to come, the WTR’s cautionary findings would be replicated by numerous other scientists in the United States and around the world, leading the World Health Organization in 2011 to classify cell-phone radiation as a “possible” human carcinogen and the governments of Great Britain, France, and Israel to issue strong warnings on cell-phone use by children. But as the taxi carried Carlo to Louis Armstrong International Airport, the scientist wondered whether his relationship with the industry might have turned out differently if cell phones had been safety-tested before being allowed onto the consumer market, before profit took precedence over science. But it was too late: Wheeler and his fellow executives had made it clear, Carlo told The Nation, that “they would do what they had to do to protect their industry, but they were not of a mind to protect consumers or public health.”14

I really want to caution you to be careful of any "expert" or EMF blogger recommending anti-radiation filtering cases, stickers that attach to the phone or necklaces to "ward off" EMF.  I get it, when I first realized 25 years ago that I was sensitive to electromagnetic energy and then later, when I understood that without a doubt, man made electromagnetic radiation has a biological effect on my body, I wanted an easy fix.  I tried the shielding materials and cases and I just did not feel any better.  Then I bought meters to see if the energy changed and I actually noticed what the California Department of Health now says and it's what the FTC and FCC post warnings about:  "Some shielding materials can make exposures worse". So please, be careful and read on for what you can do to avoid electromagnetic radiation exposure.
The easiest thing for you to do is to put a passcode on your phone. Having a passcode will make it harder for someone to pick up your phone to scroll through, access your accounts, or install something malicious. In the event that your phone gets stolen or you lose it, it’ll make it a bit harder for others to get into your phone. Most phones just ask for a 4-digit passcode, but some phones will allow you to use a more complex passcode.
According to a peer-reviewed Dec. 2006 study of 420,095 cell phone users in Denmark, the results showed a "reduced brain tumor risk" among long-term subscribers. [1] Two other peer-reviewed studies also found that cell phone users had a slightly decreased risk of developing brain tumors. A July 20, 2005 Danish study [41] found a "decreased risk for high-grade glioma," a malignant brain tumor, and a 2005 Swedish study [42] also found a "decreased odds ratio" for developing glioma as well as meningioma, another type of brain tumor.
If you’re one of the millions who missed the WHO’s news then it’s likely you also missed the fine print in Apple’s official iPhone User Guide. The part that states cell phones should be kept “5mm away from your body to ensure exposure levels remain at or below” Standard Absorption Rate (SAR). In plain language, cell phones should be at least 5mm away from you at all times, dammit.
Acute exposure of rabbits to WIFI increased heart frequency (+22%) and arterial blood pressure (+14%). Moreover, analysis of ECG revealed that WIFI induced a combined increase of PR and QT intervals. By contrast, the same exposure failed to alter maximum amplitude and P waves. After intravenously injection of dopamine (0.50 ml/kg) and epinephrine (0.50 ml/kg) under acute exposure to RF we found that, WIFI alter catecholamines (dopamine, epinephrine) action on heart variability and blood pressure compared to control. 
…Because we’ve known for a long time that the heat generated by laptops kills sperm. Well, now it turns out that heat isn’t the only threat to a man’s virility. Research has found exposure to Wi-Fi frequencies reduce sperm movement and cause DNA fragmentation. [9] Both human and animal testing has confirmed that exposure negatively affects sperm. [10] [11]
"Love it...it's ok...This iphone case is worth buying.Leather case with slot for your cards.i drop my phone accidentally and it really protect my phone and nothing even a scratch on the casing.when I bought this casing theres a coupon inside for worth $25....I'm an adult male whom has always purchased my wallets based on how many cards and what I could stuff in ... In my years of travel , I've finally realized to carry a shoulder bag for the reason I can get a Iphone case that's manufactured well & more importantly for me I'm finally limited on wallet card holders ."
Watching the rememberance programme on BBC 1 tonight it made me wonder how our prime minister could attend a remembering service in honour of those who gave their lives to keep our nation free whilst betraying our nation who democratically voted to leave the corrupt and dictitorial EU. If current roumours are true and she is plotting to keep us tied to the EU through the backdoor may she forever rue that betrayal.
The study was conducted on 16 adult male Wistar-Albino rats. The rats in the experimental group (n=8) were exposed to 2.4GHz frequency radiation for over a year. The rats in the sham control group (n=8) were subjected to the same experimental conditions except the Wi-Fi generator was turned off. After the exposure period was complete the possible DNA damage on the rat's brain, liver, kidney, skin, and testicular tissues was detected through the single cell gel electrophoresis assay (comet) method. The amount of DNA damage was measured as percentage tail DNA value.
A method of simulating thermal mapping of positioning laptop on laps of an adult man was developed. To tackle this problem, we exploited computer simulation and, to make the simulation close to the actual problem, we created 3D models of an actual laptop (Sony FW 590 Gab), antennas, and human phantom with inhomogeneous body, large number of tissues, and dispersion properties. We employed a commercial laptop Wi-Fi antenna at 2.4 GHz and a dipole antenna at 5 GHz, thermal sources with radiation powers, and human body voxel consisting of 97 tissues which were described previously. In the simulation, maximum SAR in human body was calculated 0.37 × 10−3 and 0.13 × 10−1 (W/kg) at 2.4 and 5 GHz, respectively, which was negligible according to IEEE standards; thus, the major calculated temperature elevation was due to laptop thermal sources. The temperature in glans penis, lap skin, lap muscles, and testes increased up to 37.8, 42.9, 38.8, and 37.2 °C, respectively, which was in line with clinical studies of thermal effect. Hence, the proposed method can be replicated for other scenarios. It is worth noting that the presented result cannot be easily generalized to other devices or human models. However, the whole method is replicable for similar phenomena. The recommended subject for future works can be used with the presented method for determining the effect of laptop and other devices on adult pregnant women and similar cases.
The present study determined the effects of prenatal and postnatal exposure to 2.45 GHz Wi-Fi-induced electromagnetic radiation (2h/day for 21 days during pregnancy and 21 days during lactation) on tooth and surrounding tissue development as well as the element levels in growing rats. Histological and immunohistochemical examinations between the experimental and control groups showed that exposure to 2.45 GHz EMR for 2 h per day does not interfere with the development of teeth and surrounding tissues. However, there were alterations in the elemental composition of the teeth, especially affecting such oxidative stress-related elements as copper, zinc, and iron, suggesting that short-term exposure to Wi-Fi-induced EMR may cause an imbalance in the oxidative stress condition in the teeth of growing rats.
And David Carpenter, M.D., director of the Institute for Health and the Environment at the University at Albany, says that while exposure from a single router in your home may be small, the risks could be greater in places that have dozens of laptops and routers working at the same time—such as school classrooms. Phillips notes that children’s developing bodies may be more vulnerable to all forms of radiation from devices.
MATERIAL AND METHODS: 70 male Wistar rats weighing 200-250 g were randomly divided into 7 groups (10 rats in each group).The first stage one-day test: Group A (received vitamin C 250 mg/kg/day orally together with 8- hour/day Wi-Fi exposure). Group B (exposed to Wi-Fi radiation). Group C (received vitamin C). Group D or Control (was neither exposed to radiation of Wi-Fi modem nor did receive vitamin C). The second phase of experiment had done for five consecutive days. It involved Group E (received vitamin C), Group F (exposed to Wi-Fi radiation), Group G (received vitamin C together with Wi-Fi radiation). The distance between animals' restrainers was 20 cm away from the router antenna. Finally, blood samples were collected and assayed the level of hepatic enzymes including alkaline phosphatase (ALP), alanine amino transferase (ALT) aspartate amino transferase (ASL), gamma glutamyl transferase (GGT) and the concentration of Blood Glucose, Cholesterol, Triglyceride (TG), High density lipoprotein (HDL) and low density lipoprotein (LDL).
The present study aimed to investigate the protective effects of melatonin against oxidative stress-mediated testicular impairment due to long-term exposure (2 h/day for 45 days) of 2.45 GHz Microwave Radiation. Result shows that melatonin prevented oxidative damage biochemically by significant increase (p < 0.001) in the levels of testicular LDH-X, decreased (p < 0.001) levels of MDA and ROS in testis (p < 0.01). Meanwhile, it reversed the effects of MWs on XO, protein carbonyl content, sperm count, testosterone level and DNA fragmentation in testicular cells. These results concluded that the melatonin has strong antioxidative potential against MW induced oxidative stress mediated DNA damage in testicular cells.
I’ve tried to stop using my laptop PC whose WiFi antennas I think were at the front edge on my lap since a highly skeevy lesion manifested at about my waistline. Same for any other wifi devices; I use a table or desk or bench or another chair to set it on now, not the lap. Testing the lesion naturally as if it might be cancerous, making it go away.
Wireless devices run on radio waves. Antennas emit varying levels of radio frequencies (RFs) that at some point are absorbed into the human body. The measurement of absorption, the Specific Absorption Rate (SAR), is an indicator of this absorption. What’s the SAR of a cell phone? The FCC requires that all models of cell phones sold in the U.S. fall below 1.6 watts per kilogram. If you’re confused by the complex science, you’re not alone.

48. Encourage your children to talk to you about their conversations with friends and experiences online. Make them feel comfortable talking to you if they are made to feel uncomfortable by anyone through any service while using their device. “Tell an adult you trust if you receive anything on your phone—a call, a text message, an email, a picture, or voicemail message—that makes you uncomfortable.” – Cell Phone Savvy, National Crime Prevention Council; Twitter: @McGruffatNCPC
Carlo sent letters to each of the industry’s chieftains on October 7, 1999, reiterating that the WTR’s research had found the following: “The risk of rare neuro-epithelial tumors on the outside of the brain was more than doubled…in cell phone users”; there was an apparent “correlation between brain tumors occurring on the right side of the head and the use of the phone on the right side of the head”; and “the ability of radiation from a phone’s antenna to cause functional genetic damage [was] definitely positive….”8
In the low dose, in the low intensity range we are dealing with biological effects which are clearly not linear to the SAR value, they are not linear to the energy transmitted and measured and communicated by the SAR value. So for the low intensity experiments, or the so called ‘athermal’ effects, we are very suspicious whether the SAR value is valid at all.”
Although mainstream outlets may ignore the proven dangers, especially in the US and Canada, researchers have identified several methods that can offer a level of defense. First off, reduced melatonin seems to correspond with exposure. Thus, increasing melatonin through supplementation may help offset some of the effects. [16] [17] [18] In animal tests, L-Carnitine provides antioxidant support for nutrients negatively affected by 2.4 GHz radiation. [19] [20]

With that in mind, several school districts in the U.S. and other countries have tried to reduce exposure in the classroom to RF radiation from devices. The Maryland State Department of Education, for example, recommended in 2016 that school districts use wired networks instead of WiFi whenever possible, turn off routers when not being used, and keep routers as far away from students as possible. In France, WiFi is banned from nursery schools.
Many modems provided by internet service providers are also routers pushing wifi. So even if you bought your own router and use it for your internet, you’re modem may also be pushing wifi into your home. I just ran into this personally. I was helping my mother in law set up internet in her new home. She had a router that she wanted me to set up, but when doing so I found out the modem her internet company gave her was already pushing out a wifi. Obviously, I disabled that and set up a few ethernet cables in her home.
"In conclusion, contrary to the assurances implied by Karipidis et al., existing scientific evidence clearly indicates that there are potential health risks for students and staff from microwave RF-EMR exposure levels found at schools from internal and external wireless infrastructure. ARPANSA should immediately recommend that schools use wired Internet instead of WiFi as several responsible government agencies in other parts of the world have already done to reduce exposure of children, a sensitive population that need particular protection."
