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
Lloyd is correct. I’ve worked in wireless equipment design for over 30 years, from 30kHz to 3GHz, milliwatts to many-watts. In the late 2000’s I personally set the safety standards for wireless charging (WPC’s “Qi” format) after lengthy research. Starting at 400MHz and above, DNA strands can be broken or inflicted with sequence translocation when the applied fields excite mechanical shake, twist, and compression resonances of the helixes. Those would be cancer-provoking damage. Below 300MHz I’m not aware of significant non-thermal biological effects, which explain how we’ve been “lucky” with AM/FM radio, walkie talkies, CB’s, shortwave, and VHF TV not harming people en masse.
Radiofrequency radiation from cell phones is non-ionizing and is not powerful enough to cause cancer. Ionizing radiation, including x-rays and ultraviolet light, produces molecules called ions that have either too many or too few electrons. Ions are known to damage DNA and cause cancer. Cell phone radiation, like radio, TV, and visible light radiation, is non-ionizing and lacks sufficient energy to add or remove electrons from molecules, and therefore it cannot ionize and cause cancer.  According to the authors of a 2005 peer-reviewed study of 3.7 million Swedish residents, a "biologic mechanism that could explain any possible carcinogenic effect from radiofrequency radiation has not been identified." 
What a dishonest shit article. There is no evidence that Wi-Fi does anything mentioned here. I read one of your “citations” about its link to insomnia and the study you link doesn’t even come close to mentioning WiFi. Your vague “link to cancer” citation is a local news piece. This kind of shit just reinforces people’s pseudoscientific nonsense beliefs.
Studies conducted by numerous scientific teams in several nations have raised troubling questions about possible associations between heavy cell phone use and serious health dangers. The World Health Organization has declared that cell phone radiation may be linked to brain cancer. Ten studies connect cell phone radiation to diminished sperm count and sperm damage. Others raise health concerns such as altered brain metabolism, sleep disturbance and behavioral changes in children.
Most of the research is attributed to "SPSU," which is presumably St. Petersburg State Polytechnic University, and some of the research, it is suggested, was conducted at the Kirov Military Medical Academy, though it's unclear why a military academy would conduct clinical research on civilian cell phone radiation. The names of the scientists who conducted these studies are conspicuously absent, as are any published results.
My son likes to listen to music when he sleeps. He subscribes to Spotify, and has his playlists downloaded to his phone. He now uses airplane mode at night & uses Spotify this way–but of course he sleeps w/ his phone. (He also sleeps in a basement.) Is this still dangerous? If so, what do you suggest he do to be able to listen to continuous music safely at night? He is 21 and resistant to put down the phone… but he does listen, esp. if others (esp non-Mom others!), particularly “professionals” give solid researched reasons. I am going to print this article and share it with him. (My other 3 teenagers don’t have an issue and several don’t even have a phone… but he’s my firstborn, and more into the phone…)
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.”
