ELI5: Why 5G towers and remotely read electricity meters and the EMF they emit are NOT dangerous.

I don't believe they are, but I'm after a convincing argument to use with those who do, that isn't condescending and they might consider. 

I work for a power company and get a lot people complaining that they don't want one of those remotely-read (via cell network) electricity meters so close to their kids' bedroom because of "the harmful EMF from the meter".... (while calling from a mobile phone, in their home, which surely also has wifi and a microwave oven). 

Correct me if I'm wrong, but this is tinfoil hat shit, right? I know about ionising vs non-ionising radiation, and my understanding is that therefore the EMF these people complain about is harmless and their claims that their kids "have a condition that makes them vulnerable to EMF" are bullshit.

I need to know how to explain this kindly, and hopefully turn a few conspiracy theorists and technophobes.

Googling it just gives me questionable articles that suggest maybe there is some danger. I need cold, hard, truth about why your precious kiddos aren't in any danger from you installing a smart meter.

There's two types of electromagnetic radiation (EMF): Ionizing and non-ionizing. 

Ionizing waves have high energy and a short wavelength. Since their wavelength is so short, they can interact with matter on the molecular level. A photon, a packet of light energy, will sometimes collide with an electron and knock it off its atom. This results in the atom having a net positive electrical charge. This slightly changes its chemical properties and can cause DNA molecules not to replicate properly, increasing the odds of cell going cancerous. The immune system is pretty good at dealing with a few cells that mutate like this, but enough exposure overtime will increase the likelihood of developing a tumor. The high energy of the photons can also cause burns. 

Ionizing electromagnetic radiation includes ultraviolet light, x-rays, and gamma rays.

Non-ionizing radiation is exactly what it sounds like. They have low energy and long wavelengths. Too long and too low to knock the electrons off their atoms. Though it can cause regular old burns if concentrated in one spot, by say a laser or microwave oven. 

Non-ionizing radiation includes radio waves, microwaves, infrared radiation, and visible light. 

5G operates in the microwave band, close to the frequencies used by WiFi routers. These devices use relatively low energy that's spread out over a wide area. So where as a laser focuses it in one spot, these are more like a light bulb. There is no known health risk associated with it. Any claims otherwise is strictly psudo-science. 

It's also worth mentioning that you are constantly surrounded by both natural and man made magnetic fields. The Earth generates a pretty darn big one. High energy particles also continuously bombard us from space. Any time you run current through a wire, you also generate a magnetic field. 

The more legitimate concerns over 5G are security related. Much of the infrastructure is being manufactured by Huawei, a company that has direct ties to the Chinese Communist Party. So there's worries it could be used to bug the telecom systems of rival states. But that's more a geopolitical concern than one that's going to affect the average users. At least in direct terms.
