There is a catch, though: The Internet of Things will require augmenting today’s 4G technology with 5G, thus “massively increasing” the general population’s exposure to radiation, according to a petition signed by 236 scientists worldwide who have published more than 2,000 peer-reviewed studies and represent “a significant portion of the credentialed scientists in the radiation research field,” according to Joel Moskowitz, the director of the Center for Family and Community Health at the University of California, Berkeley, who helped circulate the petition. Nevertheless, like cell phones, 5G technology is on the verge of being introduced without pre-market safety testing.26
Last year, 15-year-old English schoolgirl Jenny Fry was found hanged in woodland near her home. According to her parents she suffered from electrical sensitivity, making it impossible for her to sit in WiFi classrooms and have WiFi at home. The school refused to remove the WiFi. Speaking at the inquest her mother said, “I believe that WiFi killed my daughter.”
There is an alternative approach, rooted in what some scientists and ethicists call the “precautionary principle,” which holds that society doesn’t need absolute proof of hazard to place limits on a given technology. If the evidence is sufficiently solid and the risks sufficiently great, the precautionary principle calls for delaying the deployment of that technology until further research clarifies its impacts. The scientists’ petition discussed earlier urges government regulators to apply the precautionary principle to 5G technology. Current safety guidelines “protect industry—not health,” contends the petition, which “recommend[s] a moratorium on the roll-out of [5G]…until potential hazards for human health and the environment have been fully investigated by scientists independent from industry.”54
Cell phone storage in front pockets has been linked to poor fertility and higher chances of miscarriage and childhood cancer.  According to the Cleveland Clinic Center for Reproductive Medicine, semen quality "tended to decline as daily cell phone use increased."  According to a May-June 2012 meta-study in the Journal of Andrology, "men using mobile phones have decreased sperm concentration" in addition to "decreased viability" of their sperm. 
There is only one legitimate method of measuring cell phone radiation recognized by every major health authority and government in the world as well as by the cell phone industry itself, referred to as "SAR". SAR testing measures the "Specific Absorption Rate" of radiation at multiple depths and locations on the head and body in order to quantify how much radiation is actually penetrating it with and without certain safety devices. You can see a SAR test of the R2L device by watching the video below.
Radiation from cell phones can damage sperm. Cell phone storage in front pockets has been linked to poor fertility and higher chances of miscarriage and childhood cancer.  According to the Cleveland Clinic Center for Reproductive Medicine, semen quality "tended to decline as daily cell phone use increased."  According to a May-June 2012 meta-study in the Journal of Andrology, "men using mobile phones have decreased sperm concentration" in addition to "decreased viability" of their sperm. 
This study aimed to assess the potential harmful effects of radiofrequency-electromagnetic radiation on sperm parameters. There was no significant difference between sperm counts and sperm morphology excluding sperm motility, due to mobile phone usage period, however total motile sperm count and the progressive motile sperm count decreased due to the increase of internet usage and progressive motile sperm count also decreased with wireless Internet usage compared with the wired Internet connection usage.
In the spirit of adventure, I tried the snazzy TwelveSouth case pictured in this post, and I admit, there were some things I liked. I got very used to not carrying around a bulk in my back pocket. I even put my keycard for the office in it, and it felt very futuristic to unlock the office door by holding my phone up to the fob sensor. But in the end, I took the case off before a trip. It just seemed too foolish to risk losing everything at once.
Bluetooth allows your phone to communicate with other devices, such as the hands-free option in your car or your printer. If accessed by someone else though, they could misuse it to access your information or intercept your calls. Turn off the Bluetooth on your phone and turn it on only when you need to connect with other device. Many phones also allow users to set passcodes or additional security levels on their Bluetooth as well. Use all available options to increase your privacy.
In response, we would state that all wireless frequencies currently used by the public are categorized as radiofrequency radiation. People have not been using Wi-Fi for as long as they have been using cell phones, so the research that has looked at long term use of cell phones is very important in considering the long term health risks from wireless and Wi-Fi specifically.
I have treated patients with cancer for over thirty years as a board-certified radiation oncologist and I am familiar with every carcinogenic agent known to man. I'll tell you with absolute certainty that radio waves cannot harm you (unless perhaps you were in the path of a multi-megawatt microwave beam, in which case they might cook you. But as far as I know, there is no likelihood that this danger even exists).
Low frequency sound wave? what? They are HIGH frequency microwaves, AS IN THE SAME FREQUENCY YOUR MICROWAVE USES THAT HEATS UP FOOD! Please don’t be that guy that has no idea about this and tries to “debunk” something that is literally destroying people’s lives. – And it just simply BAFFLES me how you don’t even read the research done on the matter and boldly claim it has no effect! How ignorant and completely oblivious can one person be?!
Many modems provided by internet service providers are also routers pushing wifi. So even if you bought your own router and use it for your internet, you’re modem may also be pushing wifi into your home. I just ran into this personally. I was helping my mother in law set up internet in her new home. She had a router that she wanted me to set up, but when doing so I found out the modem her internet company gave her was already pushing out a wifi. Obviously, I disabled that and set up a few ethernet cables in her home.
The U.S. Food and Drug Administration (FDA) notes that studies reporting biological changes associated with radiofrequency radiation have failed to be replicated and that the majority of human epidemiologic studies have failed to show a relationship between exposure to radiofrequency radiation from cell phones and health problems. The FDA, which originally nominated this exposure for review by the NTP in 1999, issued a statement on the draft NTP reports released in February 2018, saying “based on this current information, we believe the current safety limits for cell phones are acceptable for protecting the public health.” FDA and the Federal Communications Commission share responsibility for regulating cell phone technologies.
We did not simply measure energy coming from the front of the case which is the area of the case where the phone would be "shielded" from radiation. If we had taken readings with a directional meter, specifically measuring energy coming from only the front or flap cover where the shielding material is, we assume as the manufacturers claim, that we would have seen a drop in the radiation readings.
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].
Non-ionizing radiation at 2.45 GHz may modify the morphology and expression of genes that codify heat shock proteins (HSP) in the thyroid gland. The present study used a diathermy model – the therapeutic application of non-ionizing radiation – on laboratory rats subjected to maximum exposure non-ionizing radiation (30 min, 10 times in two weeks) in the left front leg, in order to study the effects of radiation on the nearby thyroid tissue.Ninety minutes after radiation with the highest SAR, the central and peripheral follicles presented increased size and the thickness of the peripheral septa had decreased. Twenty-four hours after radiation, only peripheral follicles radiated at 12 W were found to be smaller. Morphological changes in the thyroid tissue may indicate a glandular response to acute or repeated stress from radiation in the hypothalamic-pituitary-thyroid axis.
Say someone found a potential association between carrying coins in your pocket and the risk of a particular type of tumor. It would set off a frenzy of activity among a group of people who were convinced that this association was real. They would lobby for a law requiring that warning signs be placed on change machines. The effect would snowball until some people would demand that the government stop minting coins.
“So what can you do? Straighten up, first of all, says Kenneth Hansraj, M.D., an orthopedic surgeon in Poughkeepsie, New York. And carry device at chest height with head up, chest open and shoulder blades back. Move just your eyes downward. And then, take a break. Your neck is not supposed to stay stuck in one position for a long period. If you’re reading on a tablet or phone, stop every so often to swivel and tilt your head — up and down, then side to side.” – 3 Dumb Things We Do with Smartphones, Good Housekeeping; Twitter: @goodhousemag
