"S8 Good...Love it...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."
The aim of the present study was to investigate the effect of 2.45-GHz electromagnetic radiation (60min/day for 4 weeks) on the oxidant and antioxidant status of skin and to examine the possible protective effects of β-glucans (50 mg/kg/day before each EMR exposure) against the oxidative injury in male rats. EMR exposure caused a significant increase in malondialdehyde levels and catalase activity, while the activities of superoxide dismutase and glutathione peroxidase decreased in skin tissues. Systemic β-glucan significantly reversed the elevation of MDA levels and the reduction of SOD activities. β-glucan treatment also slightly enhanced the activity of CAT and prevented the depletion of GSH-Px activity caused by EMR, but not statistically significantly. The present study demonstrated the role of oxidative mechanisms in EMR-induced skin tissue damages and that β-glucan could ameliorate oxidative skin injury via its antioxidant properties.
Users of wireless devices are typically exposed for much longer periods than for mobile phones and the strength of wireless devices is not significantly less. Whereas a Universal Mobile Telecommunications System (UMTS) mobile phone can range from 21 dBm (125 mW) for Power Class 4 to 33 dBm (2W) for Power class 1, a wireless router can range from a typical 15 dBm (30 mW) strength to 27 dBm (500 mW) on the high end.[6]
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.
A closer look reveals the industry’s sleight of hand. When Henry Lai, the professor whom Carlo tried to get fired, analyzed 326 safety-related studies completed between 1990 and 2005, he learned that 56 percent found a biological effect from cell-phone radiation and 44 percent did not; the scientific community apparently was split. But when Lai recategorized the studies according to their funding sources, a different picture emerged: 67 percent of the independently funded studies found a biological effect, while a mere 28 percent of the industry-funded studies did. Lai’s findings were replicated by a 2007 analysis in Environmental Health Perspectives that concluded industry-funded studies were two and a half times less likely than independent studies to find a health effect.23
No, it isn’t. It is true that International Agency for Research on Cancer (part of the World Health Organisation) has classified radiofrequency electromagnetic fields, including radiofrequency electromagnetic fields from wireless phones as ‘2b’ in its monographs on the evaluation of carcinogenic risks to humans. But that’s by no means proof of danger. You see 2b is ‘possibly carcinogenic’ and as well as Wi-Fi, the category includes coffee, carpentry and pickled vegetables. Some evidence has to be present (except when insufficient evidence is accepted) but the case does not have to be proven.

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.

Performance is good, delivered by the Snapdragon 450, though it might struggle a little bit with multitasking. We found swapping between demanding apps caused the phone to slow down a bit — but it also handled simple games fairly well, and provided solid enough performance most of the time. There are plenty of storage options too, with 32GB available as a base option, and the ability to add a MicroSD card for extra room.
BACKGROUND: The use of devices emitted microwave radiation such as mobile phones, wireless fidelity (Wi-Fi) routers, etc. is increased rapidly. It has caused a great concern; the researchers should identify its effects on people's health. We evaluated the protective role of Vitamin C on the metabolic and enzymatic activities of the liver after exposure to Wi-Fi routers.

Cell phone storage in front pockets has been linked to poor fertility and higher chances of miscarriage and childhood cancer. [18] According to the Cleveland Clinic Center for Reproductive Medicine, semen quality "tended to decline as daily cell phone use increased." [19] According to a May-June 2012 meta-study in the Journal of Andrology, "men using mobile phones have decreased sperm concentration" in addition to "decreased viability" of their sperm. [64]
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.
SUBJECT AND METHODS: In this study, we performed an analysis of the data extracted from the 45 peer-reviewed scientific publications (1996-2016) describing 169 experimental observations to detect the physiological and morphological changes in plants due to the non-thermal RF-EMF effects from mobile phone radiation. Twenty-nine different species of plants were considered in this work.
Within a relatively short time, WiFi has increased its presence in homes, offices, public spaces, coffee shops, various modes of transportation, schools, hospitals, and throughout the world. WiFi is an integral part of our lives, and it has provided unimaginable convenience: We can get information instantly, and work from most anywhere with a laptop. 
In conclusion, although EMR exposure decreased the prolactin, estrogen, and progesterone levels in the plasma of maternal rats and their offspring, EMR-induced oxidative stress in the uteri of maternal rats increased during the development of offspring. Mobile phone- and Wi-Fi-induced EMR may be one cause of increased oxidative uterine injury in growing rats and decreased hormone levels in maternal rats. TRPV1 cation channels are the possible molecular pathways responsible for changes in the hormone, oxidative stress, and body temperature levels in the uterus of maternal rats following a year-long exposure to electromagnetic radiation exposure from mobile phones and Wi-Fi devices. It is likely that TRPV1-mediated Ca2+ entry in the uterus of pregnant rats involves accumulation of oxidative stress and opening of mitochondrial membrane pores that consequently leads to mitochondrial dysfunction, substantial swelling of the mitochondria with rupture of the outer membrane and release of oxidants such as superoxide (O2 -) and hydrogen peroxide (H2O2). The superoxide radical is converted to H2O2 by superoxide dismutase (SOD) enzyme. Glutathione peroxidase (GSH-Px) is an important antioxidant enzyme for removing lipid hydroperoxides and hydrogen peroxide and it catalyzes the reduction of H2O2 to water.

Intrinsically Safe Cell Phones and Intrinsically Safe Smartphones are starting to replace dedicated camera units. If you are wanting to consolidate devices and combine an Intrinsically Safe Camera with an Intrinsically Safe Cell Phone you now can. However, there still is a need for our clients in Oil & Gas, Manufacturing, Field Services, etc. that need that extra edge in their Hazardous Areas.
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.

We can’t stop people from misleading others for profit, but we can respond to their nonsense. We’ve received more than a few letters here at How-To Geek from concerned readers asking if they should turn off their wireless equipment when not in use, or get rid of it altogether. So we’ve decided to add a reasonable voice to the conversation so, hopefully, people will find this and breathe a much deserved sigh of relief.
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)
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]
Last night unfortunately I had to sleep part of the night near a wifi router, and I felt I was being fried… as if been cooked in a microwave oven (though I never experienced that). I could hardly sleep at all until I moved (into the garden). I felt like my ovaries were directly being damaged, and felt that cyst or tumour growth would start if under longer exposure.
The HPA's position is that “...radio frequency (RF) exposures from WiFi are likely to be lower than those from mobile phones.” It also saw “...no reason why schools and others should not use WiFi equipment.”[4] In October 2007, the HPA launched a new “systematic” study into the effects of WiFi networks on behalf of the UK government, in order to calm fears that had appeared in the media in a recent period up to that time".[13] Dr Michael Clark, of the HPA, says published research on mobile phones and masts does not add up to an indictment of WiFi.[14][15]

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.
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.

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.

Anything you can do to keep the phone away from your head will help. (Even cell phone manufacturers warn consumers about this. See the previous post Cell Phone Manual Warnings for examples of warnings from Samsung, Apple and more.) If you hold the phone 2 inches away, the signal is about one-fourth the original strength. At four inches away, it’s about 1/16th as strong. Even better is a hands-free kit with a wireless air tube nearest the earpiece. (A regular wired headset can act as an antenna and make matters worse.)

“The absence of absolute proof does not mean the absence of risk,” Annie Sasco, the former director of epidemiology for cancer prevention at France’s National Institute of Health and Medical Research, told the attendees of the 2012 Childhood Cancer conference. “The younger one starts using cell phones, the higher the risk,” Sasco continued, urging a public-education effort to inform parents, politicians, and the press about children’s exceptional susceptibility.28
Two wireless trade associations contributed $4.7 million to the Interphone study launched by the WHO’s International Agency for Cancer Research in 2000. That $4.7 million represented 20 percent of the $24 million budget for the Interphone study, which convened 21 scientists from 13 countries to explore possible links between cell phones and two common types of brain tumor: glioma and meningioma. The money was channeled through a “firewall” mechanism intended to prevent corporate influence on the IACR’s findings, but whether such firewalls work is debatable. “Industry sponsors know [which scientists] receive funding; sponsored scientists know who provides funding,” Dariusz Leszczynski, an adjunct professor of biochemistry at the University of Helsinki, has explained.35
The highest typical daily exposure, according to a study of 2009, came from cellphone base stations, cellphones and DECT cordless phones, with the highest exposure locations in trains, airports and buses.[17] The typical background power of electromagnetic fields in the home can vary from zero to 5 milliwatts per meter squared.[citation needed] Long-term effects of these electromagnetic fields on human and animal health are still unknown.
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.[8]
In September 2014, Californian oncologists reported four similar case histories of young women who had developed breast cancer in precisely the areas where they normally carried their smartphones. What shocked the doctors was that these women were aged 21 to 39 and had no family history or other risk factors relating to cancer. All their cancers “had striking similarity, all tumours were hormone positive… (with) an extensive intraductal component and… near-identical morphology.” (CaseRepMed., 2013).
