With that in mind, several school districts in the U.S. and other countries have tried to reduce exposure in the classroom to RF radiation from devices. The Maryland State Department of Education, for example, recommended in 2016 that school districts use wired networks instead of WiFi whenever possible, turn off routers when not being used, and keep routers as far away from students as possible. In France, WiFi is banned from nursery schools.
RF radiation, which includes both radio waves, and microwaves, is at the far end of the electromagnetic spectrum and is a low energy wave. This makes RF and microwave radiation a form of “non-ionizing radiation” which just means that there is enough energy to move the atoms in a molecule around and cause friction, but not enough energy to actually remove a charged particle (ionizing).
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." 
Finally, if my phone is NOT in airplane mode… and I turn it off, are the RF signals still going?? I was thinking that turning the phone off is not enough.. you must have it in airplane mode (when phone is off or on) for the RF signals to stop. But #5 says “Make it a habit to either switch to flight mode or turn it off altogether when not in use.” Thanks for clarifying this; I am not a techie, so I just don’t know…

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.
Of course, trying to avoid radio wave exposure is more or less impossible if you live in modern society. Moskowitz advises keeping wireless devices away from your body and turning off wireless networks when they’re not in use. While any health risks are still theoretical, “I think trying to minimize exposure is the best advice at this point,” Moskowitz adds.
Responsibility for driver cell phone safety is the part of so many distinct factions. Consumer safety advocates oppose telecommunications lobbyists, and state lawmakers seem to avoid the larger issue of driver distractions. But without all participants it’s likely that the cell phone safety debate would lose the thrust required to effect real change. And there will be change.
We have essentially no control over whether we live or die -- except that we should avoid dangerous behaviors like smoking, becoming obese, not wearing seat belts, texting while driving, etc. Otherwise, over a trillion cells carry on countless biochemical processes that we have no control over. One out of four people will get cancer. Beyond avoiding foolish behavior, we can't influence that risk.
This study was an in-vitro pilot study which established the effect of radiofrequency radiation from 2.4 GHz laptop antenna on human semen. A test of significance between results of semen parameters using Mann-Whitney U- test at 0.05 level of significance showed a significant effect of RFR exposure on sperm concentration, motility and morphology grading.
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.
