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.
This investigation concerns with the effect of low intensity microwave (2.45 and 16.5 GHz, SAR 1.0 and 2.01 W/kg, respectively) radiation on developing rat brain when exposed for 35 days. Results showed that the chronic exposure to these radiations caused statistically significant (p<0.001) increase in DNA single strand breaks in brain cells of rat.
In subsequent analyses of Interphone data, investigators addressed issues of risk according to specific location of the tumor and estimated exposures. One analysis of data from seven of the countries in the Interphone study found no relationship between brain tumor location and regions of the brain that were exposed to the highest level of radiofrequency radiation from cell phones (9). However, another study, using data from five of the countries, reported suggestions of an increased risk of glioma and, to a lesser extent, of meningioma developing in areas of the brain experiencing the highest exposure (10).
"Love it...S8 Good...Dropped it a few times no cracks with rhis case so far, cool leds tell time or do a little dance of music whenever you do close it, it saves my battery as well because ir prevenrs the screen from turning on when rhe case is on which prevents always on display...It's a great case, the led notifications and functions are handy, it protects the phone really well; the problem is that we bought Dex and having to remove the case to be able to use Dex with my phone is a bummer; if not this will be a 5 stars review."
METHODS: Standard class V cavities were prepared on the buccal surfaces of 20 non-carious extracted human premolars. The teeth were randomly divided into 2 groups (n = 10). The control group was stored in non-environment. The specimens in the experimental groups were exposed to a radiofrequency radiation emitted from standard Wi Fi devices at 2.4 GHz for 20 min. The distance between the Wi-Fi router and samples was 30 cm and the router was exchanging data with a laptop computer that was placed 20 m away from the router. The concentration of mercury in the artificial saliva in the groups was evaluated by using a cold-vapor atomic absorption Mercury Analyzer System. The independent t test was used to evaluate any significant differences in mercury release between the two groups.
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.

The aim of this study was to investigate long-term effects of 2.4 GHz radiofrequency radiation (24 h/day for 1 year) emitted from a Wireless Fidelity (Wi-Fi) system on the testes of male rats. Results showed that sperm head defects increased in the exposure group (p < 0.05) while weight of the epididymis and seminal vesicles, seminiferous tubules diameter and tunica albuginea thickness were decreased in the exposure group (p < 0.01, p < 0.001, p < 0.0001). However, other alterations of other parameters were not found significant (p > 0.05). We suggest Wi-Fi users to avoid long-term exposure of RF emissions from Wi-Fi equipment.
The use of Wi-fi has increased rapidly in recent years. Through the use of this technology, electronic devices are connected to a computer network wirelessly using radio waves, or radiofrequency (RF) electromagnetic energy (EME), thereby eliminating or reducing the need for network cables. A common example is a laptop connected to the internet using a wi-fi modem at home. Wi-fi access points can also be found in schools and many public areas. People in a wi-fi enabled environment will be exposed to low level RF EME from time to time when using the network on computers and also from the access points. There is some public concern about potential health effects associated with RF EME emissions from wi-fi in homes, schools and other places.
Unfortunately, the current state of cell phone radiation research is similar to the early days of tobacco research. It wasn't until 1999 when the U.S. Department of Justice finally filed a racketeering lawsuit against the major tobacco companies for engaging in a "50 year scheme" to counteract any scientific evidence that showed that cigarettes are harmful to a person's health. Is the potential cell phone cancer link the same sort of scenario? Are cell phone companies funding and promoting research that "proves" no link from cell phone radio radiation in an effort to discredit those studies that are uncovering problems?
By comparison, even a very powerful high-end Wi-Fi router only produces around 1 watt of microwave energy and, unlike the magnetron in a microwave oven, a Wi-Fi router radiates that minuscule 1 watt of power in a bubble-like-cloud around the router. In other words, if you wanted to heat up even a milliliter of water above room temperature using this energy, you’d be waiting…well, forever.
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.
This study examined the possible ability of 2.45 GHz microwave radiation exposure (30 min) to modify the expression of genes that codify heat shock proteins (HSP) in the thyroid gland. Ninety minutes after radiation, HSP-90 and HSP-70 had decreased significantly (P<0.01); Twenty-four hours after radiation, HSP-90 had partially recovered and HSP-70 had recovered completely. There were few indications of lesions in the glandular structure and signs of apoptosis were negative in all radiated animals. The results suggest that acute sub-thermal radiation at 2.45 GHz may alter levels of cellular stress in rat thyroid gland without initially altering their anti-apoptotic capacity.

The objective of this study was to investigate effects of 2.437 GHz radiofrequency radiation (24h/day for 20 weeks) emitted from indoor Wi-Fi Internet access devices on rat testes using histological and immunohistochemical methods. Researchers observed significant increases in serum 8-hydroxy-2′-deoxyguanosine levels and 8-hydroxyguanosine staining in the testes of the experimental group indicating DNA damage due to exposure (p < 0.05) as well as decreased levels of catalase and glutathione peroxidase activity in the experimental group, which may have been due to radiofrequency effects on enzyme activity (p < 0.05). These findings raise questions about the safety of radiofrequency exposure from Wi-Fi Internet access devices for growing organisms of reproductive age, with a potential effect on both fertility and the integrity of germ cells.
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.
*The ability to browse the internet (for tweens and teens that have access to the internet on their cell phone) opens up an entirely new area of safety concerns. Not only can kids search the web more discreetly, most parents do not view this activity as of much of a risk as they do allowing their kids to search on a regular computer. The fact is, the dangers are just as real and even worse when you consider that with a smart phone, kids can search the internet outside of the watchful eye of parents while using their cell phone in school.
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.
I used to have an iPhone (see Why I Got Rid of My Smartphone) and discovered that no case kept the radiation from emitting. I tried the Pong Case, the Otterbox, and an RF Safe Pouch. The pouch by far was the most effective. The Pong Case was better than the Otterbox, but still showed higher levels than I would like to see. You’ll see the various levels in the video below.
The present study tested the effects of Wi-Fi (2.45 GHz for 1h) exposure on Ca(2+) influx, oxidative stress and apoptosis through TRPV1 channel in the murine dorsal root ganglion (DRG) and hippocampus of pentylentetrazol (PTZ)-induced epileptic rats. The cytosolic free Ca(2+), reactive oxygen species production, apoptosis, mitochondrial membrane depolarization, caspase-3 and -9 values in hippocampus were higher in the PTZ group than in the control although cell viability values decreased. The Wi-Fi exposure induced additional effects on the cytosolic Ca(2+) increase. However, pretreatment of the neurons with CPZ, results in a protection against epilepsy-induced Ca(2+) influx, apoptosis and oxidative damages. In conclusion, epilepsy and Wi-Fi in our experimental model is involved in Ca(2+) influx and oxidative stress-induced hippocampal and DRG death through activation of TRPV1 channels, and negative modulation of this channel activity by CPZ pretreatment may account for the neuroprotective activity against oxidative stress.

5. “Claw” your fingers around your phone. “This tight grip will make it harder for anyone to snatch your phone out of your hands. Not sure how to master the claw? No worries! CNET gives a great explanation: ‘Grip the phone securely in your hand, fanning out your fingers so that you’ve formed a protective cage or claw around the phone.’ For even more claw-like protection, you can weave your fingers around the device.” – Kyle Therese Cranston, 4 Tips for Keeping Your Cell Safe on Public Transportation, Edenred Commuter Benefit Solutions; Twitter: @CommuterBenefit
