Also being high frequency the signal travels short distances hence the need for transmitters to be located quite closely. I read somewhere that in some instances as little as 80m apart.
"I've looked into myself. You mention gamma rays as non-ionizing: they don't directly knock electrons from atoms, but I wouldn't want everyday exposure to them!"
Numbers you misread what i said, i actually said microwaves are non ionising, Gamma and X rays are high energy penetrative particles that are ionising. Alpha and Beta particles are also ionising, but not as penetrative, for example beta particles will be stopped by a sheet of plastic and Alpha particles are even less penetrative as they will be stopped within 200mm of air.

"In principle, RF levels decrease rapidly when a
person moves further away from the source, e.g.,
a transmitting antenna. For each antenna, the RF level
can be calculated based on its electrical characteristics
or measured. The distance at which the RF level is
always below the RF limit is called the compliance
distance. The compliance distance may be based on the
reference levels or an SAR evaluation, in either case
it incorporates a substantial safety margin. The figure
shows an example of a sign used to inform about
the compliance distance for RF workers."
Fleccy, there seems to be so much negative news around 5G right now. This is another negative that the telecomms companies will need to deal with - more so VOD than BT. I'm a physicist but specialized in physical electronics and semiconductor technology when I graduated in the late 80s. I've worked on the optical and (wired) access parts of telecom networks, but never been involved with wireless. I've seen a few Youtube videos mentioning the evils of 5G during this lockdown period, but it isn't something I've looked into myself. You mention gamma rays as non-ionizing: they don't directly knock electrons from atoms, but I wouldn't want everyday exposure to them!
" I don't know if it was fake news or not but I'm going to look into 5G a bit more to see what energy the 5G streetlights emit and at what frequency to determine if it poses a genuine health risk or if the people are just scaremongering"
Numbers, 5G uses a band of frequencies in the Super High Frequency, Extremely High Frequency and there's research going on to see if they can utilise Far Infrared for very High Bandwidth line of sight services within enclosed areas, such as shopping centres, Football stadiums , etc. Microwaves, unlike Gamma and X rays are non ionizing, which basically means that the don't knock electrons out of orbit and alter atoms/molecules resulting in DNA damage. What Microwaves can do is vibrate water molecules and heat water, think microwave oven. To protect telecoms workers, such as riggers, who work on masts close to the transmitters, there are safety limits that must be adhered to, but the microwave field strength reduces in power logarithmically as soon as it leaves the antenna, so is within safe limits at short distance from the transmitter.
Personally I don't see any more risk from 5G as there was from 4G, 3G, 2G, or using a walkie talkie.
I believe the US have experimented with Far Infrared for crowd control purposes, utilising high power directed beam transmission, causing a heating effect within the Human body, scaring the pants off the offending rioters. These directed beam crowd control emitters transmit far higher powers than cell sites and are also considered safe. Personally I don't see 5G as posing a health risk.
I know that this 5G COVID conspiracy theory is crazy.
It does seem that 5G may be an unnecessary step too far though. Telecomms companies are always wanting to drive innovation and each time the network gets bigger, better, faster more. IMO the 4G speeds are more than sufficient for video streaming to smartphones. The majority of people will just be using wireless with their smartphones, as they will have a fibre connection to their homes.
Why spend all the extra upgrading to 5G right now? Also with 5G the frequencies used seem to be getting closer and closer to microwave radiation. More 5G basestations are required to ensure a "decent" signal to all the urban areas. A decent signal at near microwave radiation means the 5G basestations could be cooking us more than the 4G signals. It's not something I've studied in detail myself, but I've seen people warning that energy emitted for 5G is significantly higher than 3G and 4G. People dislike cellphone basestations and the telcos are planning to get around this by incorporating mini 5G transmitters into streetlights so there won't be the need for additional masts with lots of unsightly aerials. I saw something about telcos doing a 5G trial somewhere in the NE of England and they removed all the trees growing in the pavement as these would interfere with the 5G signal from the streetlamps. There was also a photo of a tree that was allegedly next to a 5G streetlight and the nearest half of the tree to the 5G transmitter has withered and died. I don't know if it was fake news or not but I'm going to look into 5G a bit more to see what energy the 5G streetlights emit and at what frequency to determine if it poses a genuine health risk or if the people are just scaremongering.
I'll have plenty of time to do it as I live in South Africa and the technology here is a few years behind the UK. We got fibre run in our neighbourhood last year and our phones are still using 3G here.
Telecoms engineers are facing verbal and physical threats during the lockdown, as baseless conspiracy theories linking coronavirus to the roll-out of 5G technology spread by celebrities such as Amanda Holden prompt members of the public to abuse those maintaining vital mobile phone and broadband networks.
Video footage of a 70-foot telephone mast on fire in Birmingham this week has also circulated widely alongside claims it was targeted by anti-5G protesters. Network operator EE told the Guardian that its engineers were still on site assessing the cause of the fire but it “looks likely at this time” that it was an arson attack.
The problem has become so bad that engineers working for BT Openreach, which provides home broadband services, have also taken to posting public pleas on anti-5G Facebook groups asking to be spared the on-street abuse as they are not involved in maintaining mobile networks
