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).
The best things you can do are to dramatically lower the EMF radiation in your home by using less wifi, using ethernet instead, and a ton of other steps. Check out my posts “11 Ways To Reduce Computer EMF Exposure,” “11 Ways To Reduce EMF Exposure,” and “How To Eliminate EMFs In The Bedroom” for a whole wealth of helpful tips at lowering your exposure to EMF radiation.
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.
CONCLUSION: The available literature on the effect of RF-EMFs on plants to date observed the significant trend of radiofrequency radiation influence on plants. Hence, this study provides new evidence supporting our hypothesis. Nonetheless, this endorses the need for more experiments to observe the effects of RF-EMFs, especially for the longer exposure durations, using the whole organisms. The above observation agrees with our earlier study, in that it supported that it is not a well-grounded method to characterize biological effects without considering the exposure duration. Nevertheless, none of these findings can be directly associated with human; however, on the other hand, this cannot be excluded, as it can impact the human welfare and health, either directly or indirectly, due to their complexity and varied effects (calcium metabolism, stress proteins, etc.). This study should be useful as a reference for researchers conducting epidemiological studies and the long-term experiments, using whole organisms, to observe the effects of RF-EMFs.
Research on glioma brain tumors shows the average latency period is 20-30 years.  Although cell phones were introduced in 1983, it was not until 2003 that over 50% of the US population had a wireless subscription, so the 20 year mark for mass cell phone use has not yet been reached.   The May 17, 2010 INTERPHONE study, the largest study ever to examine possible links between cell phones and brain tumors, concluded that overall there was "no increase in risk" for glioma or meningioma brain tumors,  but the average user in the study had less than eight years of cell phone exposure.  In his review of the INTERPHONE study results, Dr. Rodolfo Saracci stated that "none of today’s established carcinogens, including tobacco, could have been firmly identified as increasing risk in the first 10 years or so since first exposure." 
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.
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.
when i bring my hand very close to a tuned-in radio transistor, the volume drops to almost zero and i can no longer hear the music or news unless i take my hand away from the transistor radio set. if that is the effect of em radiations from a human body on the audible signal of an electronic device reducing its audio signal to almost zero then the long-term effect of powerful em radiation of 1- 2GH frequency from a wi-fi router or a celphone must be dramatically traumatic for the human health. this has to be so because human body almost entirely functions on signals generated by ions and molecules in the body cells which are likely to be severely disrupted in the presence of such strong em radiation fields emitted by man-made external sources such as wi-fi routers and mobile phones.
In response to public concern, the WHO established the International EMF Project in 1996 to assess the scientific evidence of possible health effects of EMF in the frequency range from 0 to 300 GHz. They have stated that although extensive research has been conducted into possible health effects of exposure to many parts of the frequency spectrum, all reviews conducted so far have indicated that, as long as exposures are below the limits recommended in the ICNIRP (1998) EMF guidelines, which cover the full frequency range from 0–300 GHz, such exposures do not produce any known adverse health effect. Stronger or more frequent exposures to EMF can be unhealthy, and in fact serve as the basis for electromagnetic weaponry.
I’ve started to shut off my WIFI from midnight until about sundown the next day. The results have been astounding. I’ve been having serious joint aches and I’m not THAT old. Enough that it was hampering my quality of life. So I did an experiment. I turned off my WIFI router and took out the battery. Been doing this now for 2 days and I’m telling you I’m a new woman. I’m a little stiff getting out of bed in the morning but nothing like I was.
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!
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.
Cell phone accessories like cases serve the dual purpose of protection and showing off your sense of style. Although there have been great strides made in making cell phones and other mobile devices durable, it's still an excellent idea to protect your technology as much as you can. You also want to be able to enjoy your devices and use them as much as possible, so ensuring that your phone remains charged affords you that opportunity. No matter what kind of cell phone accessory you need, we have it for you. Save money when you buy from us thanks to the fact that we offer Every Day Low Prices.
