    We are all sitting in a giant radiation field. Cell phones, radio and TV stations, GPS and TV satellites, 2 way radios, wifi routers, and all the other electronic devices that emit signals.
    Some of it is very harmful and some of it supposedly isn't. Every cell phone is constantly transmitting to stay connected to the towers so if 5G does turn out to be harmful we are all in a lot of trouble because we will be radiated whether we have a 5G phone or not. The cell companies will roll out the technology regardless of what people want because the profit will be too much for them to ignore. Maybe after they kill of a few thousand people something will be done. Probably not until there is something to replace 5G.
    Years ago there was no manmade radiation but today it's constant. Cancer rates are increasing so maybe there is a correlation.
    I have a microwave leakage detector so I can check my microwave oven for radiation leaks. It had no leak so I'm good with using it. If it showed a leak it would be in the trash immediately.

    Let's not get rid of that one since it keeps us all alive. :)

    It would be interesting to see if anyone has done any kind of spot check studies around a city or town measuring signal frequency and strength and noting any potentially harmful EM radiation. It wouldn't surprise me if 5G could be used safely (though from what I've read, the number of repeaters/transmitters would have to be increased substantially in a fixed area to get the same reliable coverage as lesser incarnations that require fewer transmitters, which could pose a health risk), but it also wouldn't surprise me if we've been swimming in a sea of radiation that could be a health risk and is arguably unnecessary for decades. I'm not too thrilled about "smart" meters, thermostats and countless other IoT devices that constantly broadcast and receive 2gigahertz/5gigahertz signals, and they're everywhere we go. One weak signal is harmless. Are several dozen weak signals all at the same time all the time also harmless? Maybe. Maybe not. And if you can't get away from them based on where you live and work, that's a problem.

    To treat nuclear radiation you need iodine tablets. Cheap, effective and they store for decades.
    We need to separate out electromagnetic radiation from nuclear radiation: (Gamma ray, Alpha particles, Beta particles). They are very different than electromagnetic radiation.
    Sure, sticking your head in a microwave oven will expose it to lethal amounts of electromagnetic radiation.
    But that doesn't happen. As I said in an earlier post, with electromagnetic radiation, power and distance make it safe.

    Let's say you have a microwave oven that has a 1,000-watt transmitter and it warms up a sandwich 1-foot away from the transmitter.
    Given the inverse-square law, how much power would the transmitter need to warm up a sandwich 10-feet away?


    A. 4,000 watts.
    B. 10,000 watts.
    C. 50,000 watts.
    D. 100,000 watts:eek:.
    E. 256,000 watts.



    (I can still hear my math teacher screaming SHOW YOUR WORK!!!)

    Using the inverse-square law of the distance it comes out like this:
    1-foot 1,000w, 2-feet-4,000w, 3-feet 9,000w, 4-feet 16,000w, 5-feet 25,000w, 6-feet 36,000w, 7-feet 49,000w, 8-feet 64,000w, 9-feet 128,000w, 10-feet 256,000w.
    That's right, over 1/4 of a million watts. And at 20 feet it would be totally ineffective.
    It becomes obvious really fast why a 5-watt transmitter isn't going to harm you:rolleyes:.

    If you want something to worry about: gamma-rays from the sun in sunlight.
    I know at least 6 guys that spent their working lives outdoors and are getting melanomas cut off of the top of their heads.
    I'll probably join them soon:(.

    I am thoroughly uneducated on 5G, even having watched a good part of the original posted video. But what I do know is when it comes to science and technology throughout history the people are always assured by scientists (and the gov't) that whatever is safe, then way too often they later admit that it isn't or wasn't safe after all. So I will always be leery of such things.

    The list of things that were deemed safe by science or the government then turned out to be deadly is long.

    That's a little different.
    Companies have gotten into selling "software options".
    They can get hundreds or thousand$ for just a handful of 'ones and zeros'.
    Like a car on the car-lot with a bunch of expensive options that equal half the price of the car.
    It gets crazy. I've uploaded "upgrades" to machines that were only 20kilobytes (the size of 2 pages of text) for $250.
    And it's so easy to slide more and more functionality from the 'standard' column to the 'optional' column and make megabucks off of them. Boeing did.
    The buyers of the planes picked the 'economy' version without the software 'option' to make the warning light work.
    The fully-featured plane the FAA certified was perfectly safe.

    No I don't believe it's different. Feds set the requirements for a new aircraft to take to the skies.

    Indeed they do.
    The other problem is the plane was so advanced that some pilots had only flown it on autopilot.
    When the angle-of-attack sensor failed and the autopilot put the plane into a nose-dive, they wouldn't turn off the autopilot because they didn't know how to fly the plane manually.

    Back to 5G.
    It is a giant sales gimmick by phone makers and service providers to bilk customer out of $.
    Because of it's incredibly short range unless someone lives in a megalopolis like NYC or LA, it will be nothing more than a very expensive logo on your new phone to show off.
    For 5G to work, a tower will have to be within 1000 yards (within eyesight)
    99% of owners will never see a 5G connection unless they go to the 'concrete jungle'.
    Yet the phone makers know yuppies will gleefully toss their 'old' $800 phones and quickly spend $1,000+ for a 'new' 5G one:D.
    And all of the service providers (Verizon, ET-al) will be more than happy to up-charge users 20% for non-existent high-speed "compatible" service:D.
    It's a sham unless you live in the big city and there will be a line around the block everywhere of people waiting to drink the "Kool-Aid".

    5G a health hazard? No.
    Drinking the Kool-Aid, can lead to wallet damage though:rolleyes:.

    I made an upgrade to an X-Ray machine. It cost the customer $50,000. The upgrade was moving a small jumper on the motherboard. I made sure nobody was around when I made the change and it took me a whole day.

    I grew up with electronics as a hobby, especially during my teen years, I always figured there may be issues with the EMF that I was so close to but at least they weren't in the microwave frequency range that so much of modern communications operates. I knew about how microwave can cook your insides from stories that a Navy radar tech had told me. I know that cell phones run on very low power but because they are held so close to the body, it does concern me and tests have shown that where they are held against the side of the head the brain lights up. Personally, my wife and I have a Nokia Net Ten that we use for mostly emergency uses and it is turned off until we need it, it sits deep in my wife' purse. I'm not one that needs to be talking to someone while out shopping, in fact, I've kidded people that were constantly on cell phones that they probably spent more money than they should have because they weren't paying attention to what they were putting into their carts because of being distracted by their cell phones.

    Shame!
    You should have pretended to hook up a cable and laptop and played a game while you did the 'software upgrade'........like the rest of us:rolleyes:. assspank.gif

    It was in 1983, not many laptops around back then and about the only game would have been pong.
    I was still in the installation phase and I had plenty of work so it would have been hard to tell I wasn't doing a big upgrade.

    Meerkat, It all depends on the type of radiation. RF radiation can effect the body but only at certain frequencies and above certain power levels. Radiation in the form of radioactive isotopes requires a certain kind of radiation, called ionizing radiation to harm you and at levels much higher than our normal background. You can be exposed to tritium anytime you are in the ocean but some people spend a great deal of their lives in the water without harm. There are many radioactive isotopes used in medicine to provide better contrast in x-rays and MRI diagnostics. You are constantly exposed to low levels of thorium most anywhere on the planet. Your smoke, CO and CO2 detectors in your home all contain radioactive isotopes that are dangerous in large quantities but at the levels in use they cause no harm.

    The key here is to know first is it ionizing radiation or RF radiation or high energy particles. Once you know that you can determine what levels are safe.
    Your body reacts to low radiation just as it does to cuts, scrapes and broke bones. It heals the wound and makes that part stronger. You are surrounded by RF radiation no matter where you go. Raio, television, cell phones, radar and satellite signals surround us all the time. Is it safe? it seems to be based on the 100 year lifetimes that we have on earth. UV radiation and ionizing radiation at abnormal levels can cause cancer but the body usually fights them off. Not always, as in my wife's case but not everyone exposed to the same levels will get cancer.

    So, if it is going to be FASTER, does that mean I'll get tomorrow's messages yesterday...or yesterday's messages last week? Does this mean we'll be thinking faster?

    And some are "hotter" than others.
    I won't have another 'nuclear' stress test.:mad:
    I don't know of anything that would be more dangerous or more apt to cause cancer than injecting a strong ionizing-radioactive compound into someone's bloodstream.
    They do this to people every day.
    How 'hot' is it?
    (I couldn't get within 4-feet of my meter on the lowest scale without pegging the needle out. The meter is set on the highest scale in the video.)

    And people want to get paranoid about 5G:LOL:
    BTW, I (me the person) was so radioactive it was not safe (going by federal exposure limits) for a person to be within 3 feet of me.
    Be paranoid of that:rolleyes:.

    We have to notify folks at work if anyone has a nuclear stress test. It throws all the dosimeters off and will set off certain detectors when we walk by them. Those particular isotopes are pretty short half-lives, but they are HOT to start with. I'll never have another one.
