Is 5G healthy?

Nuclei in different positions in the molecule would have slightly different resonant frequencies, so you could identify the different types of bonds.

Later someone had the brilliant idea of using a computer to transform these signals into light or dark pixels in an image, so that you could use it as a scanning technique on living bodies. Bodies after all are full of water and therefore full of hydrogen atoms. But nobody wanted to be put into a "Nuclear Magnetic Resonance" machine because they feared it would make them radioactive.

So they took out the word "Nuclear" and called it Magnetic Resonance Imaging or MRI and no one is afraid any more.

Let's not forget the IV with...ahem...
"contrast" they recommend.
It's the same group that recommends paracetamol or acetaminophen for pain and tell you NOOOO . It isn't Tylenol......because they know many of you have heard that Tylenol can be bad. LOL

5G is certainly not healthy. You need to check the wave/Energy (lambda...).

have fun

More food for thought regarding 5G -- New 5G protocol vulnerabilities allow location tracking

This is an excellent example of the cybersecurity community doing its proper job. There are always vulnerabilities in new technology. The sooner they are discovered, the quicker they can be fixed. The real security scandals are vulnerabilities that hang around for years without anyone noticing them, like spectre and meltdown.

That kind of toxic situation is most likely to develop when people become afraid to report bugs because other people are liable to pounce on them for propaganda purposes.

On MRI machines, power output is only a fraction of power consumption (≤33% generally). The smartphone is 1 watt power output.

I feel every company is going to have done that analysis to avoid class action suits. Nevertheless there are sensitive people / hypochondriacs who feel harmed. If they wanted to put a mobile station in my back yard, I would refuse, but I wouldn't be worried about a phone.

The funny thing is, there was an early review of things here, and the big message was: 5G isn't there. The huge bandwidth promised is only available over very short distances, and the danger of it being available in rural parts is 0%. Cities are hostile places for line of sight transmissions and most of are stuck with 4g most of the time. Get used to it.

I'm not concerned about it. Holding the phone up directly to your ear might in the worst case be a slight issue, but that's why the speaker function was invented.

Interesting to note that somewhere (Slashdot?) reported on a device to harvest power from 5G signals, implying a higher power might be used in some places.

Interesting to note the frequencies used. they start at 410Mhz (not far above VHF) and go through UHF & EHF.

It's worth explaining that low frequencies e.g. BBC 4's 'Long wave' @198Khz basically stays low and with sufficient power will travel far. As frequencies go up, broadcasting waves are reflected down by successively higher atmospheric layers, and then pass through the atmosphere into space. To avoid losing most of the signal into space, directional aerials will have to be used. Here's an image of a directional UHF aerial. https://www.olcsobbat.hu/termek/tria...99f796e00c1ec/
The ones used in Ireland had a double row design with a gain of 13db in reception. The other option is dishes.

Presuming the phone in your pocket doesn't get any bigger, 5G is going to be primarily a line of sight thing in the bandwidth-capable frequencies. Already I'm thinking it's a service I don't want. The weak point will be uploads; I can see 5G coming in, but rarely going back.
