This is terrifying to me, because the technology here is the same as the millimeter wave "naked scanners" used at the airport. I'm not convinced of their safety, they can easily be hidden behind a wall, and god knows who could be viewing your naked body at any time.

Plus the consent issues are even worse here than the TSA.

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.

EM Radiation with a frequency of 500MHz to 5Ghz has wavelengths in the tens of centimeters. It is completely harmless and utterly unusable for „viewing naked bodies“.

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.

>this technology is completely different and has absolutely nothing in common with millimeter wave scanners

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.

Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by jakobegger on Tuesday December 12, 2017 @06:20PM (#15910452)
Microwave radiation just isn‘t suitable for imaging people. Google for „diffraction limit“ to learn why.

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.

What about pacemakers?
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by jakobegger on Wednesday December 13, 2017 @03:24AM (#15912868)
Depends on the intensity of the radiation.

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.

Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by 09bjb on Tuesday December 12, 2017 @02:01PM (#15908377)
Agreed. My deep dive (reading the academic papers, etc.) trying to confirm that the TSA millimeter wave scanners are harmless came up with more questions than answers. If this tech uses the same spectrum then I'm giving casinos a +1 for potential cancer risk.
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by syntheticnature on Tuesday December 12, 2017 @03:10PM (#15908999)
Admittedly, given every casino I've been in permits smoking, it's not like casinos were otherwise great on cancer-avoidance.

Can they see through leather?

Yes, yes they can.

What do you think they then do to your much thinner skin?

This isn't rocket science.

Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by pavel_lishin on Tuesday December 12, 2017 @03:08PM (#15908986)
Given that they can penetrate it, it's very possible that they do nothing to your skin.

You're right, this isn't rocket science - it's a blend of electrical engineering and biology.

Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by chc on Tuesday December 12, 2017 @03:06PM (#15908971)
The most obvious answer based on the previous observation is "see through your skin," not "cause cancer." I think we'll need more to go on than that.
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by joelthelion on Tuesday December 12, 2017 @03:11PM (#15909009)
Frankly, this is nothing to be terrified of:

- 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.

You work in the field of Medical Image processing so its reasonable that your opinion is biased due to the effect on your livelihood.
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by BeetleB on Tuesday December 12, 2017 @04:31PM (#15909692)
An opinion is usually biased. There's a reason it is not a fact.

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.

Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by Mister_X on Wednesday December 13, 2017 @12:46AM (#15912307)
Well, if he works in the field, he has training, so it's more likely his opinion would be based upon Fact, rather than fear of some vague unknown like you tendered.

Or maybe they know what they are talking about?
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by XR0CSWV3h3kZWg on Tuesday December 12, 2017 @04:19PM (#15909574)
Well knowing what you are talking about certainly introduces some bias.

There was a study from Johns Hopkins equating a millimeter wave scan to the amount of radiation received in a bad sunburn. Backscatter X-ray is worse than millimeter wave and if the transmitter is further away they’d necessarily have to increase the power.

I’m not sure I’d ever willingly enter a place known to be using that technology.

Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by hammock on Tuesday December 12, 2017 @06:13PM (#15910391)
Unfortunately there are unmarked trucks with backscatter X-ray scanners inside them in major cities around the world, as well as fixed backscatter X-ray scanners in many places outside of airports.

If you want to know what the trucks look like, google "ZBV": https://www.google.com/search?q=ZBV&tbm=isch

So don't go. It's not public property. Nobody is forcing you to gamble.

Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by chrismcb on Wednesday December 13, 2017 @11:46PM (#15920007)
What does this have to do with gambling? Sure a casino is using it now, but who will use it next? A hotel, restaurant, bank...
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by lifeformed on Tuesday December 12, 2017 @04:54PM (#15909868)
How are you supposed to know if they have one?
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by qbrass on Tuesday December 12, 2017 @05:24PM (#15910062)
Presume they all do and plan your trip accordingly.
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by apple4ever on Tuesday December 12, 2017 @06:02PM (#15910318)
I won't.
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by apple4ever on Tuesday December 12, 2017 @06:01PM (#15910306)
Absolutely agree. Apart from the silliness of banning people that are less criminal than cops, its scary to be exposed to those type of waves.

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?

Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by hammock on Tuesday December 12, 2017 @03:25PM (#15909124)

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?

Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by CompanionCuuube on Tuesday December 12, 2017 @03:28PM (#15909153)
The solution is having a legal requirement for adequate notification to all consumers that such monitoring is happening.
Re:A Las Vegas Resort Using Microwaves to Keep Guns Out by chrismcb on Wednesday December 13, 2017 @11:47PM (#15920008)
Have guns in a hotel been a common problem for you? Can't you just stay somewhere else?
