Per the article these are hidden and used to secretly scan guests, so if there is any adverse effects you have no way of knowing what caused it, reporting it, and seeking corrective measures.
We also have to consider edge cases (pace makers, sensitive electronics, children, etc), and how they'll detect & correct when these devices malfunction.
Ultimately this is a medical device used in a non-medical way with non-medical oversight.
People have studied EM radiation for a very long time, and we know what‘s dangerous. Xray is dangerous, UV at high intensity is also dangerous, radio frequncy/micro wave is harmless (unless you go to really high intensities, but then you’d fry all electronics nearby)
Maybe check a physics textbook before you get all worked up.
Edit: Also, this technology is completely different and has absolutely nothing in common with millimeter wave scanners.
Radio frequency and microwave band emissions are strictly regulated, so if they want to sell these devices, they need to keep emissions below a limit, just like Wifi routers and Microwave ovens.
Do you have a source? It's described as using an antenna and a receiver, which is exactly how the naked scanners at the airport work: https://en.wikipedia.org/wiki/Millimeter_wave_scanner#Techni...
They may use different frequencies (airport scanners are in 24–30 GHz band) but it's the same technology.
That‘s why the devices in this article, unlike millimeter wave scanners, can‘t create an image of the scanned subjects. (and it’s also the reason why why millimeter wave scanners make very blurry images).
Instead, these detectors look for resonances in the emmitted spectrum.
The article was a bit light on details, but this description sounds very much like an old school metal detector, rather than an imaging device.
Yes, yes they can.
What do you think they then do to your much thinner skin?
This isn't rocket science.
You're right, this isn't rocket science - it's a blend of electrical engineering and biology.
- re viewing your naked body: this only gives blurry black and white reconstructions. Frankly, nothing to make a fuss about. I doubt anyone would even be recognizable on those images.
- re safety: this may be a valid concern, but if there is a health effect, it will be tiny, because we are already bathed in microwaves all day long.

Not exactly sure what you're trying to say. If you work in a liberal city, your opinion likely has a bias. If you are at a certain educational level, your opinion likely has a bias. If you are male/female, your opinion likely has a bias. If you were raised in a poor/rich family, your opinion likely has a bias. All your life experiences contribute to your opinion having a bias.
I’m not sure I’d ever willingly enter a place known to be using that technology.

So don't go. It's not public property. Nobody is forcing you to gamble.
I never go through those scanners for a reason.
Personally, if this is the cost of keeping guns out of a hotel I'm staying at, I'm all for it. If this is a deal breaker for you, can't you just stay somewhere else?
Gladly. I opt out of the scanners at the airport. However the scanners in the hotel are secret and hidden. How do I opt out now?
