Radiofrequency radiation is a form of electromagnetic radiation. Electromagnetic radiation can be categorized into two types: ionizing (e.g., x-rays, radon, and cosmic rays) and non-ionizing (e.g., radiofrequency and extremely low frequency, or power frequency). Electromagnetic radiation is defined according to its wavelength and frequency, which is the number of cycles of a wave that pass a reference point per second. Electromagnetic frequencies are described in units called hertz (Hz).
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
Result: More than 100 studies on 2.45 GHz radiation were analyzed, most of which found changes compared to the control groups at levels below the safety guidelines of the International Commission on Non-Ionizing Radiation Protection (ICNIRP) (issued as exposure limits of the 26th Federal Pollution Control Ordinance (BImSchV) in Germany). The available studies document damage to the reproductive system, impacts on the EEG and brain functions, as well as effects on the heart, liver, thyroid, gene expression, cell cycle, cell membranes, bacteria, and plants. As a mechanism of action, many studies identify oxidative stress. Adverse effects on learning, memory, attention, and behavior are the result of cytotoxic effects.
The agency is finally moving to meet the realities of the 21st century and the Information Age. On June 15, FCC chairman Julius Genachowski circulated a proposal to his four fellow commissioners calling for formal review of the 1996 regulations. To advance, his plan must be approved by a majority of the commissioners. If they agree, the FCC could take the long overdue step of modernizing its safety standards. But the pace is likely to be glacial.
The animals were exposed to an access point (AP) from WIFI device (D-Link DWL-3200 AP with 802.11 g mode and WPA2 network protection) as previously described in Salah et al. (2013). WIFI integrated two omnidirectional antennas that were setup for internet broadcast via wireless at 2.45 GHz. The sham control rabbits were placed under the same condition without applying RF (0 Hz). Antennas of WIFI were placed at 25 cm at the right side near the heart (animal in dorsal decubitus).
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." 
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
The iPad case is made of real leather, a natural and organic material, and allows you or your children to use an iPad safely, without having to worry about radiation pouring from the pad as you read, write, watch TV's or movies, or play your favorite games. It contains all the necessary heat and radiation shielding to keep you safe from iPad radiation, including protection from:
Cell phone safety is a top priority for people all over the world—especially those with children. There are many tips for ensuring that both you and your kids are using your cell phone or smartphone safely—from being careful when you cross the road, to learning the driving laws in your area, which way to carry your phone for radiation reduction, and monitoring and limiting the amount of time your child or teen spends using their device.
