Fear Some. Better than Fear Less??

I read this morning that the NYPD have developed a scanning gun that will tell if you’re carrying a gun in your pants from 16 feet off.

My first thought was to google: terahertz wave scanner dangers…

And Voila…

From Scotty Starnes’ Blog:

MIT: Terahertz Waves Tear Apart DNA (Same Waves Used In NYPD Gun-Scanning System)

published a story yesterday about the NYPD, and the Department of Defense, using new body scanners to conduct “virtual frisks” on the citizens of New York using Terahertz Imaging Detection. These new scanners use terahertz waves to detect if someone may be carrying a weapon. MIT published information that shows these waves can tear apart DNA.

From Technology Review:

…But what of the health effects of terahertz waves? At first glance, it’s easy to dismiss any notion that they can be damaging. Terahertz photons are not energetic enough to break chemical bonds or ionise atoms or molecules, the chief reasons why higher energy photons such as x-rays and UV rays are so bad for us. But could there be another mechanism at work?

The evidence that terahertz radiation damages biological systems is mixed. “Some studies reported significant genetic damage while others, although similar, showed none,” say Boian Alexandrov at the Center for Nonlinear Studies at Los Alamos National Laboratory in New Mexico and a few buddies. Now these guys think they know why.

Alexandrov and co have created a model to investigate how THz fields interact with double-stranded DNA and what they’ve found is remarkable. They say that although the forces generated are tiny, resonant effects allow THz 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. That’s a jaw dropping conclusion.

And it also explains why the evidence has been so hard to garner. Ordinary resonant effects are not powerful enough to do do this kind of damage but nonlinear resonances can. These nonlinear instabilities are much less likely to form which explains why the character of THz genotoxic effects are probabilistic rather than deterministic, say the team.

This should set the cat among the pigeons. Of course, terahertz waves are a natural part of environment, just like visible and infrared light. But a new generation of cameras are set to appear that not only record terahertz waves but also bombard us with them. And if our exposure is set to increase, the question that urgently needs answering is what level of terahertz exposure is safe.

I don’t think I’ll be the first to say it. I miss the good old New York of the 80’s where stabbings and shootings were the norm. This brave new world of nut cancer guns is too much….
