It contains all the necessary heat and radiation shielding to keep you safe from iPad radiation, including protection from:
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.

This study aimed to investigate the effect of 2.4 GHz Wi-Fi radiation (12 h/day for 30 days) on multisensory integration in male rats. Results demonstrated that rats in Wi-Fi exposure groups could not discriminate significantly between the novel and familiar objects in any of the standard SOR, tactile SOR, visual SOR, and CMOR tests and the expression of M1 receptors increased following Wi-Fi exposure. In conclusion, results of this study showed that chronic exposure to Wi-Fi electromagnetic waves might impair both unimodal and cross-modal encoding of information.
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.
Our recommendation is to reduce your exposure from wireless sources. We advocate what’s referred to as the Precautionary Principle. Basically, this means that because there’s research, lots of it actually, saying the energy that powers our cellphones (RF radiation) could be causing health concerns like tumors and cancer. We ought to take care when using our cell phones and all devices that emit RF, using them mindfully.
We have a safe search tools for kids. It is more of a phone friendly version of our site that automatically ensures safe search is on at http://www.safesearchkids.com/app.html or enter “Safe Search Kids” in your phones app store to get the links. Having your tweens and teens agree to use this version of search will automatically ensure safe filtering is always on. That said, you still need to set up guidelines that allow you to view history on their phone when needed, as well has having them promise to not delete their history knowing you may look at it.
the Environmental Working Group is suspending publication of the EWG guide to cell phones until the FCC makes the responsible decision to require cell phone makers to generate and disclose data about device and network emissions under real-world conditions. We strongly believe that as cell phones become more powerful and ubiquitous, it is critical that people have a right to know how much radiation they can expect their cell phones to generate. As things now stand, the FCC’s cell phone safety rules are as obsolete as the StarTac.
This is a 2 pieces of plastic sandwiched together by glue. Don't believe me? Take it apart. This item works no better than the existing case on your phone. If you are that concerned with cellphone radiation, you should be equally concerned about the cheap plastic and toxic glue that this is comprised of. Also know the fact that they've stolen $25 from your wallet when you purchase this hokey product...Technology at it's finest.
Our studies point that WIFI is not completely safe at home near the animal or human body because it employ harmful radio waves. But it is safer compared to cellphone that it is close to our brain during communications. WIFI signals are everywhere. If you switched off your WiFi at night, you are still exposed to the WIFI signals coming in from neighbors but we have a significant reduction of the bioeffects of WIFI with distance from the router. Future investigations will focus on the long term bioeffects of WIFI placed at an important distance from the animal or the human.
This is true…. i feltmore awake after using wi fi& even struggled to sleep through d night .it was like something very hard holding my consuntration power of mind…i was addicted of using wi fi.conditions r stable & im well now……this is nothing but just a future danger that will not allow u to consuntrate on ur own mind &body…wifi is bloddy monster addiction but i m out of it though the blessings of spiritual lord….I LOVE U WAHEGURU JI
The NTP studied radiofrequency radiation (2G and 3G frequencies) in rats and mice (33, 34). This large project was conducted in highly specialized labs that specified and controlled sources of radiation and measured their effects. The rodents experienced whole-body exposures of 3, 6, or 9 watts per kilogram of body weight for 5 or 7 days per week for 18 hours per day in cycles of 10 minutes on, 10 minutes off. A research overview of the rodent studies, with links to the peer-review summary, is available on NTP website. The primary outcomes observed were a small number of cancers of Schwann cells in the heart and non-cancerous changes (hyperplasia) in the same tissues for male rats, but not female rats, nor in mice overall.
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).
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.    In animal tests, L-Carnitine provides antioxidant support for nutrients negatively affected by 2.4 GHz radiation.  
Although uterine lipid peroxidation increased in the EMR groups, uterine glutathione peroxidase activity (4th and 5th weeks) and plasma prolactin levels (6th week) in developing rats decreased in these groups. In the maternal rats, the plasma prolactin, estrogen, and progesterone levels decreased in the EMR groups, while the plasma total oxidant status, and body temperatures increased. There were no changes in the levels of reduced glutathione, total antioxidants, or vitamins A, C, and E in the uterine and plasma samples of maternal rats.
36. Teach your kids to ignore anonymous calls or texts. It’s one thing for adults to choose to answer anonymous calls or text messages, but kids may not always know how to detect a scammer and may unknowingly reveal personal information that could be used in malicious ways. “An anonymous call could be someone trying to extract personal information. An anonymous text could be phishing.” – Rob Zidar, 13 Cell Phone Safety Tips for Teens, Pre-Teens and Their Parents, Lawrenceville Patch; Twitter: @LawvilleNJPatch
One thing I am totally shocked by is the resistance that people seem to have to believing that something that promotes “Convenience” for them, could be dangerous. I am Electromagnetic Hypersensitive and I am involved with numerous groups of people worldwide who are suffering from the detrimental effects of wireless radiation. These groups are growing substantially as people become more and more aware that their health issues can be traced back to consistent exposure to microwave radiation that has NO proven record or research to prove its safety. From my own experience, placed in a Wi-Fi field, every muscle in my body contracts like I’m being electrocuted, lumps begin to form from the effect of blood thickening, I get massive headaches, chest pain (the heart struggling due to sticky red blood cells), and eventually total paralysis from the severe fatigue that even makes it hard to breath. So many people are suffering from illnesses they haven’t even traced back to Wi-Fi but if they succeed at globalizing it, I’m sure you’ll all find out eventually as you accumulate the effects. Thank you Dr Edward Group for posting this invaluable information.
The very next day, a livid Tom Wheeler began publicly trashing Carlo to the media. In a letter he shared with the CEOs, Wheeler told Carlo that the CTIA was “certain that you have never provided CTIA with the studies you mention”—an apparent effort to shield the industry from liability in the lawsuits that had led to Carlo’s hiring in the first place. Wheeler charged further that the studies had not been published in peer-reviewed journals, casting doubt on their validity.10
Industry-funded scientists had been pressuring their colleagues for a decade by then, according to Leszczynski, another member of the Lyon working group. Leszczynski was an assistant professor at Harvard Medical School when he first experienced such pressure, in 1999. He had wanted to investigate the effects of radiation levels higher than the SAR levels permitted by government, hypothesizing that this might better conform to real-world practices. But when he proposed the idea at scientific meetings, Leszczynski said, it was shouted down by Mays Swicord, Joe Elder, and C.K. Chou—scientists who worked for Motorola. As Leszczynski recalled, “It was a normal occurrence at scientific meetings—and I attended really a lot of them—that whenever [a] scientist reported biological effects at SAR over [government-approved levels], the above-mentioned industry scientists, singularly or as a group, jumped up to the microphone to condemn and to discredit the results.”44
“When symptoms are not addressed comprehensively– for example, using symptom amelioration without simultaneous elimination of exposure – cell membrane adverse reaction and damage continue to occur while the patient is assuming the cause of the problem has been eliminated. This lulls patients into a false sense of security, causing them to aggravate their exposures through the increased use of their wireless devices. When the damage reaches a critically harmful level, even the symptom amelioration can no longer be sustained by the damaged cells.”
26. Learn about the potential effects of radiation on reproductive health. “I would recommend that [Consumer Reports] forewarn its readers not to keep their cell phones near their genitals. We have substantial evidence that cell phone radiation damages sperm in males and some evidence of reproductive health effects (i.e., neurological disorders) in human offspring as well as mice for females exposed to cell phone radiation during pregnancy. We also have preliminary evidence of increased breast cancer risk for women who kept cell phones in their bras.” – Dr. Joel M. Moskowitz, The 4 Cell Phone Safety Tips Offered By Consumer Reports Isn’t Enough, RFSafe; Twitter: @rfsafe
You probably can’t get away from the effects of Wi-Fi. Even if you disconnect your own router – which probably would be very disruptive to your life – you are exposed to Wi-Fi at work, where you shop and in your neighborhood. You can protect yourself, though, with a range of effective and affordable products from SafeSpace. For more information, click here.
Purpose: This article is a systematic review of studies on the effects of non-ionizing radiation at the microwave (MW) frequency of 2.45 GHz (2450 MHz), which is predominantly used in WLAN/Wi-Fi applications (wireless local area network) and microwave ovens. Newer WLAN standards also use the frequency ranges of 5 GHz, 6 GHz, and 60 GHz. WLAN, referred to generically in this review also as Wi-Fi, has become the technology of choice for many wireless applications because providers do not require a license, making the service free to users. To meet users’ desire to be online all the time, more and more WLAN antennas (access points, femtocells, routers) emitting pulsed 2.45 GHz radiation are being installed at libraries, hospitals, hotels, airports, railway stations, shopping malls, public places, and in buses, subways, and passenger trains. Wi-Fi consoles are used to play games. Office and household appliances are also fitted with Wi-Fi antennas. Residential routers often contain two Wi-Fi transmitters. As part of its digital learning initiative, the German Conference of Ministers of Education has decided to provide all schools with Wi-Fi networks. The extensive body of research on the health risks of Wi-Fi radiation is generally not considered by policy-makers or in the public debate.

Bluetooth allows your phone to communicate with other devices, such as the hands-free option in your car or your printer. If accessed by someone else though, they could misuse it to access your information or intercept your calls. Turn off the Bluetooth on your phone and turn it on only when you need to connect with other device. Many phones also allow users to set passcodes or additional security levels on their Bluetooth as well. Use all available options to increase your privacy.

So of course now that we understand that the cases are not tested and just the material--it makes sense! We measured power density levels all around the case-the shielding material most likely isn't used "all over" because then the phone couldn't receive signal and wouldn't be able to engage in a call. That's why we did not see even close to a 99% reduction when some cases were on the phone. In fact, watch the video and you'll see some readings are more than 20% higher with a case on vs the naked phone.
In recent years there has been a tremendous increase in use of Wi-Fi devices along with mobile phones, globally. Wi-Fi devices make use of 2.4 GHz frequency. The present study evaluated the impact of 2.45 GHz radiation exposure for 4h/day for 45 days on behavioral and oxidative stress parameters in female Sprague Dawley rats. Behavioral tests of anxiety, learning and memory were started from day 38. Oxidative stress parameters were estimated in brain homogenates after sacrificing the rats on day 45. In morris water maze, elevated plus maze and light dark box test, the 2.45 GHz radiation exposed rats elicited memory decline and anxiety behavior. Exposure decreased activities of super oxide dismutase, catalase and reduced glutathione levels whereas increased levels of brain lipid peroxidation was encountered in the radiation exposed rats, showing compromised anti-oxidant defense. Expression of caspase 3 gene in brain samples were quantified which unraveled notable increase in the apoptotic marker caspase 3 in 2.45 GHz radiation exposed group as compared to sham exposed group. No significant changes were observed in histopathological examinations and brain levels of TNF-α. Analysis of dendritic arborization of neurons showcased reduction in number of dendritic branching and intersections which corresponds to alteration in dendritic structure of neurons, affecting neuronal signaling. The study clearly indicates that exposure of rats to microwave radiation of 2.45GHz leads to detrimental changes in brain leading to lowering of learning and memory and expression of anxiety behavior in rats along with fall in brain antioxidant enzyme systems.
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
This study was an in-vitro pilot study which established the effect of radiofrequency radiation from 2.4 GHz laptop antenna on human semen. A test of significance between results of semen parameters using Mann-Whitney U- test at 0.05 level of significance showed a significant effect of RFR exposure on sperm concentration, motility and morphology grading.
I thought I was getting Alzheimers until I read this study. I also had insomnia. I couldn’t focus, concentrate or remember anything. My energy levels were tanked. I felt like I was turning into a vegetable. I was ready to leave the planet, I was getting So depressed… I immediately disabled the wifi and put 2 laptops on an ether net and EVERY SINGLE SYMPTOM CLEARED UP!!!
Thank you for this information. I will be looking in to all of this. We have shut off our wifi and have hardwired our house. A cell tower was put in to our neighborhood .08 mile away 5 years ago and we’re just now looking in to the implications of living so close to one. We have a 3 1/2 year old and a 9 month old. My 3 1/2 year old is always complaining of her eyes hurting or a headache. I’m thinking it’s time to sell and move. Thank you again! I appreciate you getting back with me.
Wireless internet using durations: When we compare the wireless internet users regarding the duration of internet usage, there were a significant decrease of total motile sperm count and progressive motile sperm count (p = 0.032 and p = 0.033; respectively; Table 3) ... there were no significance among the semen parameters regarding the wired internet group (p = 0.128).
Also of note, in a study by Henrietta Nittby et al (2009), the lowest exposure SARs were worse than the higher SAR exposures. Some scientists consider blood brain barrier effects at these very low levels of radiation exposure (i.e. 30-45x lower than the ‘Top 10’ lowest SAR phones ranked by the Environmental Working Group) to be of equal or even greater concern for the population than the increase in brain tumors from cell phone use that is expected.
The aim of this study was to investigate the possible protective role of selenium and L-carnitine on oxidative stress induced by 2.45-GHz radiation (60min/day for 28 days) in heart of rat. Electromagnetic radiation exposure was found to cause oxidative stress in the heart of rats. There is also an apparent protective effect of selenium and L-carnitine by inhibition of free radical formation and support of the antioxidant redox system.
Exposure to ionizing radiation, such as from x-rays, is known to increase the risk of cancer. However, although many studies have examined the potential health effects of non-ionizing radiation from radar, microwave ovens, cell phones, and other sources, there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans (2).
Released in 1993 as a joint creation of IBM and BellSouth, this was the first smartphone. A fax machine, a PDA, a pager and a mobile phone, the IBM Simon featured no physical keys, but used a touchscreen and optional stylus. Amazingly, it included applications such as games, email, a notepad, calculator, world clock, address book and a calendar. It only sold in the United States, for $899.
Increasingly, more people are reporting symptoms associated with WiFi radiation, or non-ionizing radiation, such as headaches, nausea, dizziness, and loss of concentration. Some governments and public bodies are choosing to take precautionary measures, as this topic continues to be studied, by banning or regulating WiFi in public places and schools.
For example, the latency period for radiation induced malignancies is, on the average, say 20 years, but epidemiologic studies of large groups of people (that only require a few thousand patients to reach statistical significance) exposed to ionizing radiation start showing an increase above baseline by seven years. So conservatively, there should be at least a few excess cases of glioma caused by cellular (or WiFi) electromagnetic radiation by now.
After years of warnings, we are fairly used to ensuring we have anti-spyware, anti-malware, and anti-virus programs on our computers. This software should also be used on our smartphones as well. Search for programs in the app stores and discuss them with your wireless provider. Some phones come with built-in software that you won’t want to override.
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.
The HPA also says that due to the mobile phone's adaptive power ability, a DECT cordless phone's radiation could actually exceed the radiation of a mobile phone. The HPA explains that while the DECT cordless phone's radiation has an average output power of 10 mW, it is actually in the form of 100 bursts per second of 250 mW, a strength comparable to some mobile phones.
According to an anonymous questionnaire, daily active cell phone usage was divided into three groups as following: Group A, < 30 min/d; Group B, from 30 min/d to 2 h/d; and Group C, > 2 h/d. Habits of carrying a mobile phone was recorded as (A) in the pocket of trousers, (B) in a handbag, or (C) in the pocket of jackets. Wireless internet usage was divided in to three groups, Group A: < 30 min/d; Group B, from 30 min/d to 2 h/d; and Group C, > 2 h/d. Internet usage types recorded as wireless or not.
ShieldMe On the ShieldMe site is a message from Wireless Connection CEO Rose Vitale addressing issues with the cellphone industry and she makes some good points. As far as how ShieldMe works she states, " Our ShieldMe cases help deflect up to 99% of the harmful EMF, RF or microwave radiation emitted from a cellphone while carrying around or when on a call." The demonstration of the SheildMe case shows levels that like the "EMF protection cellphone cases" is many many times higher than levels EMF expert Larry Gust follows as a certified building biologist.
The RF signals from cell phones, as well as Bluetooth and WiFi, are considered nonionizing forms of radiation. That means unlike ionizing radiation—from, say, ultraviolet light from the sun, medical tests such as CT scans or X-rays, or nuclear explosions—they don’t carry enough energy to directly break or alter your DNA, which is one way cancer can occur.
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
TEXT MORE THAN TALK! Moving a cell phone even a 1/4 inch from the body can greatly reduce radiation exposure, at one inch the intensity is 16 fold less than 1/4 inch. Signal strength falls off as the square of the distance from the source. This means that if you double the distance to the source, RF intensity is four times less since two squared is four.
The aim of this study was to investigate the long-term effects of 2.4 GHz radiofrequency radiation (24h/day for 12 months) emitted from a Wireless Fidelity (Wi-Fi) system on some of the miRNA in brain tissue in male rats. The results revealed that long-term exposure of RFR radiation can alter expression of some of the miRNAs, indicating that this type of exposure may lead to adverse effects such as neurodegenerative diseases originated from the alteration of some miRNA expression and more studies should be devoted to the effects of RF radiation on miRNA expression levels.
Five properties of non-thermal EMF effects are discussed. These are that pulsed EMFs are, in most cases, more active than are non-pulsed EMFs; artificial EMFs are polarized and such polarized EMFs are much more active than non-polarized EMFs; dose-response curves are non-linear and non-monotone; EMF effects are often cumulative; and EMFs may impact young people more than adults.
MATERIALS AND METHODS: The study was carried out on 16 Wistar Albino adult male rats by dividing them into two groups such as sham (n = 8) and exposure (n = 8). Rats in the exposure group were exposed to 2.4 GHz radiofrequency (RF) radiation for 24 hours a day for 12 months (one year). The same procedure was applied to the rats in the sham group except the Wi-Fi system was turned off. Immediately after the last exposure, rats were sacrificed and their brains were removed. miR-9-5p, miR-29a-3p, miR-106b-5p, miR-107, miR-125a-3p in brain were investigated in detail.

This study used Drosophila as model organisms to assess the effects of various EMF sources (short time daily for 3-7 days) on apoptotic cell death of follicles during oogenesis and reproductive capacity (fecundity) decline. Sources included: 900/1800 MHz mobile phone, 1880-1900 MHz wireless base, wireless handset, mobile phone-handset combination, 2.44 GHz wireless network (Wi-Fi), 2.44 GHz bluetooth, 92.8 MHz FM generator, 27.15 MHz baby monitor, 900 MHz CW RF generator and microwave oven’s 2.44 GHz RF and magnetic field components. All EMF sources used created statistically significant effects regarding fecundity and cell death-apoptosis induction, even at very low intensity levels well below ICNIRP’s guidelines, suggesting that Drosophila oogenesis system is suitable to be used as a biomarker for exploring potential EMF bioactivity.

Consumers need -- now more than ever -- real-world, relevant data on how much radiation their phones emit under various circumstances. The FCC does not require the cell phone industry to disclose these data. One important study showing that certain networks could expose consumers to 30 to 300 times more radiation than other networks was hidden from the public until the information was dated to the point of irrelevancy.
Wi-Fi transmissions consist of sequences of RF burst signals or pulses ranging in duration depending on the amount of data being carried by a pulse(15). The proportion of time that Wi-Fi transmits RF signals is called the duty cycle. Joseph et al.(14) in measuring Wi-Fi in 176 different urban locations (outdoors, homes, offices) found a median duty cycle of 1.4% over all the measurements. Particularly in schools, Khalid et al.(10) in measuring Wi-Fi in six schools found a mean duty cycle from the access points of 4.8%. In our study duty cycle was measured separately for the 2.45 and 5 GHz transmissions when performing the stationary Wi-Fi measurements in the centre of the classroom. The median duty cycle for 23 schools that were measured in the current study was 6.3 and 2.4% for 2.45 and 5 GHz transmissions, respectively.
Most phones have a GPS that can pinpoint your general or exact location. With this capability, many applications may collect and share your location information. However, many smartphones give you the option of managing your location sharing under the “settings.” You can pick and choose which applications may access your location or you can opt to turn off the location setting altogether. Minimizing the location access can also help increase the battery life on your phone. If your phone doesn’t offer specific location-sharing settings, choose carefully when downloading new apps so you’re not sharing your location unknowingly.
