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.

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]
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.
On the basis of current scientific information, ARPANSA sees no reason why wi-fi should not continue to be used in schools and in other places. However, ARPANSA recognises that exposure to RF EME from wi-fi and other wireless devices can be of concern to some parents. ARPANSA will continue to review the research into potential health effects of RF EME emissions from wi-fi and other devices in order to provide accurate and up‑to‑date advice.
According to American Academy of Pediatrics President Dr. Robert Block, when cell phones are used by children, "the average RF energy deposition is two times higher in the brain and 10 times higher in the bone marrow of the skull," than for adults. [68] A July 2008 peer-reviewed study shows that children under the age of eight absorb twice the amount of radiation into their brain tissue as adults due to their lower skull thickness. [17]
It’s also packing a decent camera, so your kid can share selfies without worrying about the quality. It’s not perfect, and the battery life might not last as long as you’d like — but Motorola’s TurboPower charging means 15 minutes of charging can give six hours of battery life. Sit your kid down to dinner and plug their phone in, and it should be more than ready to see them through to bedtime. All in all, the Moto G6 is an extremely solid phone that should serve your child well.
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.
What the study showed: Most published analyses from this study have shown no statistically significant increases in brain or central nervous system cancers related to higher amounts of cell phone use. One analysis showed a statistically significant, although modest, increase in the risk of glioma among the small proportion of study participants who spent the most total time on cell phone calls. However, the researchers considered this finding inconclusive because they felt that the amount of use reported by some respondents was unlikely and because the participants who reported lower levels of use appeared to have a slightly reduced risk of brain cancer compared with people who did not use cell phones regularly (4–6).
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.
To shed a bit more light on it – powerline electromagnetic fields have different (though not necessarily better) biological effects. 50/60Hz powerline fields alter ion transport across intra- and inter-cellular membranes, accelerating or inhibiting chemical reactions, depending on the reaction. Also within the reception range of bulk brainwave action. So not the greatest thing for physical and mental health. As you go higher in freq range, the effects become more just thermal and neurostimulative at high enough field strength. From 400MHz on up the issue becomes field-excitation of mechanical shaking of DNA strands resulting in sequence breakage and translocations – not great for cancer risk… for those really bored and curious, read the studies bibliography of IEEE C95.1-2005. I found C95 and its underlying studies to be the most helpful body of work when setting the safety standards for inductive wireless charging.
It will fit any iPad that is approximately 9.5″ x 7.3″. This includes 1st, 2nd, 3rd, and 4th generation iPads and iPad Airs. You simply insert your iPad directly into this case. With superior heat and radiation shielding, this is the only iPad case you’ll need. The leather is very thick and strong, so it will also protect your iPad from physical damage.

Just take a moment and think about how much you’re using your phone every single day. Answering calls, discussing plans, talking about your day with friends, playing games, watching videos and using apps, only scratch the surface of how much you’re actually using your phone. You might even have it by your bedside or on your nightstand when you go to bed at night. It’s time you stopped exposing yourself to dangerous EMF radiation and protected yourself from the dire consequences of using an unshielded smartphone or tablet.
It should be noted that the given values of SAR were normalized to 1 W peak antenna power output, while typically a WLAN antenna radiates about 10 mW; therefore, for a real world operating system, maximum SAR of 0.37 × 10−3 and 0.18 × 10−3 (W/kg) is expected for 2 and 1 active antennas, respectively, which are 104 times lower than the European safety limit (2 W/kg) [IEEE Standard for Safety Levels with Respect to Humans, 2005].
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’ve bought a computer any time in the last 5 years, there is almost a certainty that it has wifi built in. We’re far past the days of getting separate wifi cards or adapters for our computers. The problem is, Wifi does emit RF radiation, a type of EMF radiation that is very harmful. Whether you have a desktop computer or a laptop that you use, it likely uses Wifi, so let’s take care of that.
Joel Moskowitz (@berkeleyprc) of the University of California, Berkeley School of Public Health, US, says: “This is the largest technological experiment in the history of our species, with potential health risks we still know next to nothing about.” This view is shared by Denis Henshaw, professor of human radiation effects at Bristol University, UK, who said: “Vast numbers of people are using cell phones and this could be a time bomb of health problems.”
