This can "unzip" DNA according to studies, but last month, NYPD Commissioner Ray Kelly told CBS New York that his department is looking to deploy these Terahertz Imaging Detection scanners on the street in the war on “illegal guns.” Never mind that it BLATANTLY violates your 4th Amendment right.
An engineer now files a law suit against these New York Body Scanners.

A passive scan should be able to pick up ambiant THZ frequencies just fine.

Quick question: Does the temp make a difference here?
Absolutely. That is just a standard response curve for 1.00 emissivity and a perfect black body source. That's why such passive scans can work. Each material weather it be skin, cloth, metal, etc... have a different response curve. now I won't pretend to know that such resolution and technology of seeing such spectra at such fine resolutions actually exist, but I find the OP as just a "fear-mongering" story, since such levels of terahertz radiation is available.
Care to either support or dismiss my words, or are you going to continue to be a "peanut gallery" voice in these forums?
^ This ing guy
^ legit question
I have not done any research so I can say much about this devise but if WC or Agloco can find out if the hazards are legit I would appreciate any input.
THZ wavelengths have been studies. I did some reading before making my second post in this thread. At certain frequencies resonate with genetic base pairs. They have been deemed as dangerous by some, and I would say that is probably so. Still, it depends of the intensity of exposure, and probably total exposure time.
I ask again, are these active or passive scans. A passive system would not be dangerous at all. An active system probably would be, at least past certain power outputs.
If these systems being talked about use passive scanning, then the OP has no merit, other than the concerns of privacy. But we already have public cameras.

Agloco knows already. WC will have to go fish.
You would surprised how much WC knows in fact his research is in the top 5 of people online these days
Research sure, results, not so much.
Try debating him on 9/11 evolution or Apollo he is the lance Armstrong of debaters
So he's EPO doping and lying about it?
oi @wildcobra
if u have nothing to hide, why would u care how these clowns use the equipment?
Why?
I understand all I wish to. I have better things to learn more about than this.
Are these active or passive scanners? (suggests you know the difference and the ramifications of each)
You post like you're the forum guru on any technology related topic. How can you say, with a straight face, that you have better things to learn more about?
I do know the difference. I saw no where in my search, and design specs indicating which way it was. I pointed out that passive scanning, where no THZ signal is emitted, is not dangerous.
I do know more than most people, but I'm no guru.
I'm not wasting my time looking everything. The OP claims these are dangerous. I pointed out that they might not be.
Think of it as a camera, simply looking at these frequencies instead of visible light frequencies. Now in a low light situation, we would use a flash. We are now supplying source energy. This would be like the active scan.
Did you understand the reason I supplied the image from spectralcalc?
Ever use a camera made by Flir? I have.

After you Googled it
lol no, you're just the one who opens his flapper about it. There are experts here, you aren't one of them. You think that, because they don't address Mouse's trolls, it's your calling to flex.I do know more than most people, but I'm no guru.
After Googling. Do you really need to point out a "might"?I'm not wasting my time looking everything. The OP claims these are dangerous. I pointed out that they might not be.
Thanks for the lesson, prof.Think of it as a camera, simply looking at these frequencies instead of visible light frequencies. Now in a low light situation, we would use a flash. We are now supplying source energy. This would be like the active scan.
Yes, your misguided ego made it a requirement.Did you understand the reason I supplied the image from spectralcalc?
lolEver use a camera made by Flir? I have.
All that even the pic.
Are you suggesting you knew about this prior to this thread? Because I would bet that you Googled it just to respond to this thread.
Are you suggesting that using the camera makes you educated in the physics behind it? Do you know how charge coupled devices work? If you've used a CCD camera, you should.

Yes, I already knew these things. I knew to go to spectralcalc for the response curve. I know about various frequency spectra. What I don't know is precisely how their system works. Probably no information out there on it. It's probably proprietary.
How about instead of being an insulting head, that you tell us what I am wrong about.

i don't want the policing hitting me with , that is assault
Think laser, mirrors, detector, blah blah blah. Basically a stepper with a higher frequency.
What are you making up?
There are no health hazards to what they are proposing. They are simply looking at the energy already radiating from the human body, and looking for the silhouette of what blocks the body heat. They are likely going to a lower frequency than the typical IR that a thermal camera would see, that is what allows them to see through clothing.
Being able to see through clothing though...
I would consider this a serious 4th amendment issue.
Why does my bull detector start going off when you talk about scientific studies?
A study published in 2010 and conducted by Boian S. Alexandrov and colleagues at the Center for Nonlinear Studies at Los Alamos National Laboratory in New Mexico[18][19] created mathematical models predicting how terahertz radiation would interact with double-stranded DNA, showing that, even though involved forces seem to be tiny, nonlinear resonances (although much less likely to form than less-powerful common resonances) could allow terahertz waves to "unzip double-stranded DNA, creating bubbles in the double strand that could significantly interfere with processes such as gene expression and DNA replication".[20] Experimental verification of this simulation was not done. A recent analysis of this work concludes that the DNA bubbles do not occur under reasonable physical assumptions or if the effects of temperature are taken into account.[21]
One study, speculative, and not verified by actual subsequent experimentation.

Modelling DNA Response to THz Radiation
Terahertz radiation is, essentially, emitted by every bit of matter with a temperature over 10 Kelvins, FWIW.
