With all the talk about 5G and what not, I figured I would write up a post about realistic radio wave risks and mitigation.

Distance is your friend. Radio waves, unless specifically aimed using a phased array antenna or other targeting tech, disperse from their source with respect to distance squared. This means being 4 feet away from the source will result in 1/4 the radiation as being 2 feet away. The further away, the better.

I have a TRIFIELD TF2 and a GQ EMF 390 (EMF / ELF / RF meters), and i've measured the energy levels from various devices under various circumstances at various ranges, in order to get a better understanding of what kind of energy levels we are dealing with on a day-to-day basis.

Most notable findings:

1. If you activate Siri on an iPhone (press and hold home button on an SE or iPhone 8), the gigahertz range radiation will be in the 8 milliamps per meter squared range for the duration of the interaction.
2. Your Wi-Fi router pulses in the multiple milliamps per meter squared range 5-10 times per second (constantly).
3. Your phone will randomly (even when not apparently using data according to the little icons on the top) go into the multiple milliamps per meter squared range for minutes at a time for no apparent reason.
4. Your Bluetooth headphones will broadcast well in the danger zone directly into your brain the entire time they are in your ear, especially while actively using them.
5. If you use a Fitbit or other wearable, including an Apple Watch or other "smart watch", it will constantly broadcast radiation directly into your arm and also into your body from close range. The Fitbit will pulse well into the danger zone multiple times per second.
6. If there is a 5G or LTE tower anywhere near your home (5G within 100 yards, LTE within perhaps a half mile), then I would recommend purchasing one of the meters that I mentioned above, so that you could take measurements from various points on your property and make sure there are no hot zones. It's probably a good idea to do this anyway, unless you live somewhere in the country and there are no towers nearby.

Tips:

1. Do not place your router within 10 feet of where you plan to be sitting or lying on a regular basis, and if you don't need Wi-Fi and can get away with just cat-5 connection, then get rid of a wireless router all together; it is by far the most powerful projector of radiation in your house.
2. Purchase a radiation shield that is meant for putting under your laptop (they are expensive, like $100), and put it in front of your router, if your router is in your living room (i.e., you're sitting in front of it). It won't block enough signal to affect your connection, but it will block a significant amount of the energy reaching you while you're sitting on your sofa watching homosexual propaganda on Netflix.
3. Do not keep your phone on your nightstand next to your head. If anything, use your charging cable as a tether to keep your phone on the floor nearby, so that you can grab the cable and pull your phone up if you need it, while otherwise leaving it on the floor overnight so that it's at least 4 feet away from you. Ideally, keep your phone 6 or more feet away from you. I know most of us here probably read stuff like this at night, so throwing your phone like a frisbee 10 feet away across the room when you're done is not realistic.
4. If you do live right near a tower, move. There's no way around this. You could spend a lot of money to shield your house from the radiation, or you could line the insides of all your walls with aluminum foil (little to no effect on direct close source radiation), but neither of these options is even remotely ideal. Just get out of there.
5. As loony as it may sound, purchase a few rolls of aluminum foil to keep in your house, because a cheap way to produce a Faraday cage is by simply lining your walls with aluminum foil as mentioned above, and in the event of some kind of actual radio wave attack (not suggesting that this is going to happen, but I am suspicious of the fact that these multinational corporations want to place dangerous radio towers on every block in America). I feel like spending 10 or 15 bucks on insuring the ability to turn your living room into a Faraday cage, if needed, would not be a bad waste of money. Again, I realize this is a little bit out there, but this stuff is real and there are real risks and nobody knows the full extent of those risks. Better prepared than unprepared, in the event that they turn these towers on "permanent headache mode" or "everyone gets diabetes this week mode".
6. Because you can use aluminum foil to create a faraday cage, you might assume that it follows that you could also use aluminum foil to block radiation sources (like your router). This is not the case. You need a thick piece of steel or lead for this. I did try to put five or six layers of aluminum foil in front of my router as an experiment, but it didn't seem to have any effect whatsoever on the amount of energy received by the meters. Faraday cages act kind of like an antenna, not like a shield. So for direct source blocking / protection, you need a shield. Two shields is better than one, three is better than two, etc. I have two of these laptop shields, and I decided to place both of them in front of our router. One of them has a decent effect at limiting the amount of energy to safe levels when I am about four or 5 feet away. When I place both of them in front of it the levels drop well below safe levels even from 2 feet away. If you can afford some kind of industrial grade/commercial shield of some kind, rather than just a consumer laptop shield, this would be ideal for any kind of dangerous source (like a smart meter on the outside of your woodframe house). I don't know if we have a smart meter, but our meters are all the way on the opposite end of our house from where we ever are, and our house is concrete, so I'm not concerned, but these smart meters pulse much higher energy levels than even a router.
7. Once again, distance is your friend. If you have something in your house that you need that broadcasts gigahertz radiation, keep that as far away from your resting places as possible (so far, bed, etc. As long as it is at least 20 feet away from anywhere that you will be sitting regularly, you will likely be OK, even without a shield. I was not able to measure any dangerous levels of energy beyond 20 feet from our router. The one exception to this distance rule would be smart meters as I mentioned above. If you have a smart meter, I would recommend testing the levels inside your house nearby, especially if you have like a kids room right against that wall or something. If there's a smart meter on the other side of the wall from your babies crib, that baby is going to develop permanent problems because of this. I guarantee it.
