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.
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.
And yet, a lot of people do use these, including people I know and respect. I see people on the subway playing Candy Crush, the cover of their folio-style wallet case folded back, all of their cards just flapping in the wind. And don’t just take my word for it: The Silk iPhone wallet case has nearly 2,000 reviews on Amazon with an average score of 4.5 stars. People not only use these cases—they love them!
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 analyzed cellular stress levels in rat thymus after exposure to a 2.45 GHz radio frequency (RF) using an experimental diathermic model in a Gigahertz Transverse Electromagnetic (GTEM) chamber. The thymus tissue presented several morphological changes, including increased distribution of blood vessels along with the appearance of red blood cells and hemorrhagic reticuloepithelial cells, while the glucocorticoid receptors presented greater immunomarking on the thymic cortex in exposed animals. These results indicate that non-ionizing sub-thermal radiation causes changes in the endothelial permeability and vascularization of the thymus, and is a tissue-modulating agent for Hsp90 and GR.

Exposure to electromagnetic radiation (EMR) is rapidly increasing in everyday environment, consequently conferring potential health effects. Oxidative stress is emerging as a mechanism implicated in pathophysiology and progression of various diseases. To our knowledge, no report has been made on the status of antioxidant redox systems after continuous exposure to radiofrequency radiation emitted from a Wi-Fi access point in animal model so far. Therefore, we aimed to continuously subject rats in the experimental group to radiofrequency (RF) radiation emitted from a commercially available Wi-Fi device. Male Wister rats were exposed to 2.45 GHz RF radiation emitted from a Wi-Fi for 24 h/day for 10 consecutive weeks. In order to assess the change in antioxidant redox system of plasma after continuous exposure to a Wi-Fi device, the total antioxidant capacity of plasma, level of thiobarbituric acid reactive substances, concentration of reduced glutathione (GSH), and activity of different enzymatic antioxidants, e.g., superoxide dismutase [SOD], catalase [CAT], glutathione peroxidase [GSH-Px], and glutathione S-transferase [GST], were measured. In the Wi-Fi exposed group, a significant decrease was detected in total antioxidant capacity of plasma and the activities of several antioxidant enzymes, including CAT, GSH-Px, and SOD (P < 0.05). Meanwhile, the GST activity was significantly increased in this group (P < 0.05). However, no significant changes were found in GSH and TBARS levels following exposure to RF radiation. According to the results, oxidative defense system in rats exposed to Wi-Fi signal was significantly affected compared to the control group. Further studies are needed to better understand the possible biological mechanisms of EMR emitted from Wi-Fi device and relevant outcomes.
RESULTS: The results revealed that long-term exposure of 2.4 GHz Wi-Fi radiation can alter expression of some of the miRNAs such as miR-106b-5p (adj p* = 0.010) and miR-107 (adj p* = 0.005). We observed that mir 107 expression is 3.3 times and miR- 106b-5p expression is 3.65 times lower in the exposure group than in the control group. However, miR-9-5p, miR-29a-3p and miR-125a-3p levels in brain were not altered.

If you are concerned about the possible health effects of radio wave radiation emitted by your cell phone, your options are simple and cheap. This kind of radiation is at its highest levels nearest the antenna. Also, not all cell phones are created equal. Sar Shield offers a useful radiation chart for cell phones that provides an accurate "Sar rating" for every cell phone model. It's important to realize that at these low radiation levels, if you keep the cell phone away from your head and body, you are perfectly safe. However, if you'd rather not use a headset, then there are plenty of resources to obtain a radiation shield for your phone.
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!
On the opposite side of things, we have non-ionizing radiation. This radiation does not have enough energy to ionize atoms, and includes everything else on the radiation spectrum including infrared radiation, visible light, and radio waves  — including everything from the kind of low-energy radio waves we use for walkie-talkies to higher energy radio waves like those in the microwave portion of the spectrum.

The study was an attempt to draw attention towards the adverse effects of non-ionizing electromagnetic radiations (NI-EMR) in the frequency that is used widely in the field of telecommunication. Many studies have captured the impact of the 900 MHz and 1800 MHz frequencies, however the frequency of radiation in Wi-Fi range has not been much explored. Along with the use of cell phones there is a growing concern with the use of Wi-Fi devices which continuously emit radiations in the frequency of 2.4 GHz. Hence we thought it prudent to investigate the impact of radiation of the frequency of 2.45 GHz. It can be concluded that the exposure to non-ionizing radiation of 2.45 GHz caused detrimental changes in rat brain leading to learning and memory decline and expression of anxiety behavior along with fall in brain antioxidants. The exposure triggered the gene expression of caspase 3 which plays a major role in the apoptotic pathway. The chronic impact of non-ionizing radiation needs to be thoroughly evaluated in humans so that combative steps can be taken.
In today's world, 2.45-GHz radio-frequency radiation (RFR) from industrial, scientific, medical, military and domestic applications is the main part of indoor-outdoor electromagnetic field exposure. Long-term effects of 2.45-GHz Wi-Fi radiation on male reproductive system was not known completely. Therefore, this study aimed to investigate the major cause of male infertility during short- and long-term exposure of Wi-Fi radiation.
So for example, if you have a Samsung Galaxy S 5 you could turn it off completely (briefly pulling the battery if you need to) push the power button to turn the phone back on until you see the Samsung Galaxy S5 logo screen, release the power button and then immediately press and hold the Volume Down key until the phone booted up with Safe Mode activated displaying “Safe mode” in the bottom left hand corner of the phones display.
Like cell phones, routers use radio frequency (RF) energy—a form of electromagnetic radiation—to bring wireless internet to your computer, TV, and other devices. Bluetooth headphones and speakers also rely on RF signals to play music. Smartwatches use RF to connect to your phone. And any WiFi-connected smart devices in your home also receive and transmit data using this type of energy. Do you need to worry about any of that?
“If you’re experiencing eye discomfort, make your phone’s font size bigger. Mark Rosenfield, O.D., Ph.D., told Men’s Health that phone users should try to hold their phones at least 16 inches away from their faces. Every few minutes look up from your screen at something far away for short breaks, and don’t forget to blink.” – Amanda Hawkins, 5 Seriously Bad Side Effects of Your Smartphone Addiction, Good Housekeeping; Twitter: @goodhousemag
But researchers can make some judgments about the potential for harm based on how WiFi and similar technologies work, as well as on how people tend to use their devices. Those factors do provide some reasons to think that WiFi and Bluetooth devices may be less of a concern, says Leeka Kheifets, Ph.D., a professor of epidemiology at the UCLA School of Public Health who has studied the potential health effects of low-level radiation.
A few years ago, the science regarding links between cell phone radiation and various health ailments was a very emergent science. Even today, most scientists disagree about many of the findings. However, the fact that so many new studies are discovering effects that cell phone radiation can have on human biology, it makes sense to play it safe. If there are no negative health effects, then you're only out a few bucks. But if it turns out there really are serious health issues related to cell phone radiation, then by protecting yourself early, you can protect your health and potentially save your life by getting a cell phone anti-radiation shield.

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

The cell phone pocket shield allows you to use your earbuds or headphones during a call but at the same time, safely place your cell phone in your pocket, purse, etc. This means you are protected both when the phone is connected on a call or sitting idle. The shield will not interfere with your cellular signal and will not negatively affect battery life.
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.
You can search for the most popular cell phone cases and covers, browse cases and covers by brand, and even refine your search by need. Cell phone cases provide a variety of protection. Some people put a large emphasis on military-grade protection, to ensure that all angles of their case are secure, no matter the terrain. Others may desire cases that give easy access to headphone ports or charging outlets, to have access to home speakers or audio cables. The engineering of cases can become even more specific—right down to the beveled edges that raise your screen protectively above a flat surface or the grip finish smoothly designed onto the back of your phone to ensure maximum ease in typing. Whatever your need, Amazon is sure to carry the brand, features, and colors you care about. Check the Deals page regularly to even see some of your favorite cases on discount. Amazon is sure to carry the widest selection of cases; you just worry about carrying yours.
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. 
Most wireless LAN equipment is designed to work within predefined standards. Wireless access points are also often close to humans, but the drop off in power over distance is fast, following the inverse-square law.[9] However, wireless laptops are typically used close to humans. WiFi had been anecdotally linked to electromagnetic hypersensitivity[10] but research into electromagnetic hypersensitivity has found no systematic evidence supporting claims made by sufferers.[11][12]
The king is dead — long live the king. If you’re looking for a smartphone that doesn’t break the bank and won’t sting too much if it’s lost, but still offers good performance, then Motorola’s G-range is usually where you’d start. This year, the Moto G6 has upped the ante, delivering a glass-and-metal design that your sprog won’t be ashamed to be seen with. A protective case is included in the package, but you might want to pick from our range of the best Moto G6 cases, since glass is prone to breaking.
Most of the research is attributed to "SPSU," which is presumably St. Petersburg State Polytechnic University, and some of the research, it is suggested, was conducted at the Kirov Military Medical Academy, though it's unclear why a military academy would conduct clinical research on civilian cell phone radiation. The names of the scientists who conducted these studies are conspicuously absent, as are any published results.
37. Be careful when sharing your phone number. Teenagers may be so excited to finally have their own cell phone or smartphone that they immediately give out their number to everyone they know – or worse, publish it online on their social media profiles. “Only give out your phone number to people you know for sure you can trust.” – Sameer Hinduja, Ph.D. and Justin W. Patchin, Ph.D., Cell Phone Safety Ten Tips for Teens, Cyberbullying Research Center; Twitter: @onlinebullying
Electrocardiogram and arterial pressure measurements were studied under acute exposures to WIFI (2.45GHz) during one hour in adult male rabbits. 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, but failed to alter maximum amplitude and P waves. After intravenously injection of dopamine (0.50ml/kg) and epinephrine (0.50ml/kg) under acute exposure to RF we found that, WIFI alter catecholamines (dopamine, epinephrine) action on heart variability and blood pressure compared to control. These results suggest for the first time, as far as we know, that exposure to WIFI affect heart rhythm, blood pressure, and catecholamines efficacy on cardiovascular system; indicating that radiofrequency can act directly and/or indirectly on cardiovascular system.
Whether you call them cell phones, smart phones or mobile devices, it seems like everyone has one. According to the wireless telecommunications industry, the U.S. now has an estimated 300 million mobile subscribers, compared to 110 million subscribers a decade ago. The increase in cell phone use has generated concern about possible health risks related to radiofrequency electromagnetic fields from this technology, and a market for shields as possible protection against the radio waves the phones emit. The Federal Trade Commission (FTC), the nation's consumer protection agency, has some practical tips to help you avoid scams and limit your exposure to electromagnetic emissions from your cell phone.
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.
It’s worth remembering that Wi-Fi occupies the same part of the spectrum as microwaves, which sounds terribly alarming. If it can boil water, surely it’s bad for us too? Well, no. Not at such low power. This is also the frequency of the cosmic background radiation, the echoes of the big bang that fill the sky. There is literally nowhere in the universe that does not have microwaves pinging around in it.

The advent of Wi-Fi connected high technology devices in executing day-to-day activities is fast evolving especially in developing countries of the world and hence the need to assess its safety among others. The present study was conducted to investigate the injurious effect of radiofrequency emissions from installed Wi-Fi devices in brains of young male rats. Animals were divided into four equal groups; group 1 served as control while groups 2, 3, and 4 were exposed to 2.5 Ghz at intervals of 30, 45, and 60 consecutive days with free access to food and water ad libitum. Alterations in harvested brain tissues were confirmed by histopathological analyses which showed vascular congestion and DNA damage in the brain was assayed using agarose gel electrophoresis. Histomorphometry analyses of their brain tissues showed perivascular congestion and tissue damage as well.

In today's world, 2.45-GHz radio-frequency radiation (RFR) from industrial, scientific, medical, military and domestic applications is the main part of indoor-outdoor electromagnetic field exposure. Long-term effects of 2.45-GHz Wi-Fi radiation on male reproductive system was not known completely. Therefore, this study aimed to investigate the major cause of male infertility during short- and long-term exposure of Wi-Fi radiation.
RESULTS: Our analysis demonstrates that the data from a substantial amount of the studies on RF-EMFs from mobile phones show physiological and/or morphological effects (89.9%, p < 0.001). Additionally, our analysis of the results from these reported studies demonstrates that the maize, roselle, pea, fenugreek, duckweeds, tomato, onions and mungbean plants seem to be very sensitive to RF-EMFs. Our findings also suggest that plants seem to be more responsive to certain frequencies, especially the frequencies between (i) 800 and 1500 MHz (p < 0.0001), (ii) 1500 and 2400 MHz (p < 0.0001) and (iii) 3500 and 8000 MHz (p = 0.0161).
The environmental exposure to RF radiation in some schools is higher than reported levels for non-thermal biological effects. In order to reduce children’s exposure to RF radiation, schools should prefer wired network connections, allow laptop, tablets, and mobile phone usage only in flight mode and deactivate Wi-Fi access points when internet is not needed for learning purposes.
But researchers can make some judgments about the potential for harm based on how WiFi and similar technologies work, as well as on how people tend to use their devices.

And, it’s not just sperm. The results of an animal study suggest that some wireless frequencies may prevent egg implantation. During the study, mice exposed 2 hours a day for 45 days had significantly increased oxidative stress levels. The cellular damage and impact on DNA structure from exposure suggest a strong possibility of abnormal pregnancy or failure of the egg to implant. [12]
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.
In those cases, however, there are two important things to note. The person exposed to the non-ionizing microwave radiation would be exposed to a very high power dose at a very close range. The magnetron in your average consumer microwave produces about 700 watts of microwave energy, and that microwave discharge is safely contained within the body of the microwave thanks to proper shielding. Even if the microwave was malfunctioning and the shielding was beginning to fail, you wouldn’t even feel anything standing in the same room as the device.

Cooper's prototype arrived on the market a decade later at the staggering price of $3,995. Designed by Rudy Krolopp, it was known as the Motorola DynaTAC 8000X, or simply "the brick.” Featuring 20 large buttons and a long rubber antenna, it measured about 11 inches high, weighed almost 2 pounds, provided one hour of battery life and could store 30 phone numbers.
We did not simply measure energy coming from the front of the case which is the area of the case where the phone would be "shielded" from radiation. If we had taken readings with a directional meter, specifically measuring energy coming from only the front or flap cover where the shielding material is, we assume as the manufacturers claim, that we would have seen a drop in the radiation readings.
This overview shows that effects of 2.45 GHz radiation have been found by different research teams, repeatedly, in different study objects, and at different exposure levels. A broad spectrum of issues has been investigated such as the effects of 2.45 GHz radiation emitted by a Wi-Fi router on the release of mercury from amalgam fillings. The mercury levels were significantly increased (Paknahad et al. 2016).

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!"

Niels Kuster, a Swiss engineer, initially filed a conflict-of-interest statement affirming only that his research group had taken money from “various governments, scientific institutions and corporations.” But after Kuster co-authored a summary of the WHO’s findings in The Lancet Oncology, the medical journal issued a correction expanding on Kuster’s conflict-of-interest statement, noting payments from the Mobile Manufacturers Forum, Motorola, Ericsson, Nokia, Samsung, Sony, GSMA, and Deutsche Telekom. Nevertheless, Kuster participated in the entire 10 days of deliberations.39


This study investigated the long-term effects of low-level 2.45GHz MW irradiation (2h/day for 30 days)  on the reproductive function of male mice and its mechanism of action. Researchers observed that MW irradiation induced a significant decrease in sperm count and sperm viability along with the decrease in seminiferous tubule diameter, degeneration of seminiferous tubules, reduction in testicular 3β HSD activity and reduction in plasma testosterone levels. Increased expression of testicular i-NOS was observed in the MW-irradiated group of mice. These adverse reproductive effects suggest that chronic exposure to nonionizing MW radiation may lead to infertility via free radical species-mediated pathway.
In April, the city of Berkeley, Calif., won a major decision in a federal appeals court, allowing the city to go forward with its ordinance requiring cellphone retailers to provide consumers with information about safe cellphone use. The court denied a request by the the mobile phone industry's lobby, CTIA-The Wireless Association, which had fought the city’s attempts to educate its citizens.

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]


In this study, the effect of Wi-Fi radiation exposure as a threat to brain health was studied using genomic analysis and histopathological study which showed the high risk of its genotoxicity especially in prolonged exposure spectrum through the findings from this study. The genomic analysis confirmed DNA damage due to Wi-Fi radiation toxicity and DNA damage effect which was seen through the RAPD profiles of animals from the exposed groups. The histopathological analyses also confirmed significant deleterious alterations in the brain tissues of Wi-Fi-exposed animals. Hence, the need to exhibit caution in handling smart devices that are used from day to day is fast becoming a threat to human health and wellness.
Cell phone radiation levels are tested and certified to remain within levels deemed safe by the Federal Communications Commission (FCC). The FCC sets the maximum amount of thermal radiation (heat) that cell phones are permitted to emit. [3] This limit is measured as the amount of radiation absorbed by a user and is known as the specific absorption rate (SAR). In 1996 the SAR for cell phone radiation was set at a maximum of 1.6 watts of energy absorbed per kilogram of body weight. Manufactures of cell phones must test their products to ensure that they meet this standard. Random tests of phones on the market by FCC scientists further ensure that radiation levels meet FCC guidelines. [48] 

Keep in mind that even if someone doesn’t have access to your phone, it might be possible for them to access your online account. Online accounts can include your wireless carrier account, call logs, your email or social media accounts, your Google Play/Apple AppStore, or iCloud account. Update the passwords and security questions for those accounts to ensure someone else can’t get access.

The most critical concept when it comes to talking about radiation is the distinction between ionizing and non-ionizing radiation. Ionizing radiation is the dangerous stuff and includes x-ray radiation, gamma radiation, and some amount of ultra-violet light on the high end of the ultra-violet spectrum. The key element here is the wavelength of the radiation type.

Nevertheless, Kuster participated in the entire 10 days of deliberations.39
Members of the public often ask about the cumulative exposure that a child receives when using a Wi-Fi device in a classroom in which a number of children are simultaneously using Wi-Fi. When downloading files, most of the transmissions will be from the access point, not the students’ device. When downloading and uploading only a portion of the maximum capacity of a network would be used even in a classroom filled with children using Wi-Fi. The Wi-Fi network divides RF transmissions among the access points and client devices therefore the individual RF exposure to a child in a classroom that is using a device consists of sequential exposures from all active devices, the majority of which are located at some distance away(15). For the majority of schools (20) the measurements in the current study were conducted in an empty classroom (to avoid lesson disruption) with an access point and one laptop. In three schools, measurements were conducted with students or teachers present and using Wi-Fi devices. A comparison between measurements conducted in empty classrooms and classrooms with multiple students/teachers using Wi-Fi showed no significant difference in the RF levels (p > 0.1 for all); although this may have been due to low numbers (only three schools measured with multiple users in the classroom).
42. Limit your child’s time on the phone. There’s much discussion about how much screen time is good for kids and teens today, and today’s wireless devices provide access to all the games, chatting features, web browsers, media, and apps they could possibly consume in a lifetime. Setting clear limits on smartphone usage will help you keep screen time within reasonable limits. “Half an hour of screen time is recommended for children 4-5 years old; an hour for ages 5-10; and two hours for high school aged kids.” – Melanie Medina, Growing up Digital – Cell Phone Safety for Kids, Identity Force; Twitter: @IdentityForce
