Since 9/11, airports in the United States have been on full alert. People are stopped constantly for a pat down or a body check, and even new advances in technology to ensure the safety of passenger were created. It only took a couple of months for the TSA to announce that they would be using THz Scanners at certain airports. If you didn’t know this, THz scanners are highly controversial, not only because airport staff can see everything we have on our body, but because they emit Terahertz (THz) radiation. This has created much concerns as these radiation wave have the potential of shredding the human DNA.  Early this year it was also reported that NYC Police and the U.S. Department of Defense would fund research to get police some portable THz Scanners. And this is just the tip of the iceberg, as soon it may be possible to come in contact with this radiation just by your cell phone alone!

The idea is literally to have cell phone see through walls with the new THz Scanner attached to them. Why cell phones would need this is really something I would like answered. Though at most they will only be able to see less then four inches ahead, this doesn’t leave out the possibility of it ever increasing. Either way, this could prove to be more harmful then it seems as any user may be exposed to the radiation of THz.

Dr. Boian Alexandrov,  Center for Nonlinear Studies at Los Alamos National Laboratory in New Mexico, has explained that humans who have come into contact with these waves risk a potential of having their own DNA destroyed. This exposure builds up, and eventually unzips the strands of DNA found in humans and other living organisms.

[quote]“We consider the influence of a terahertz field on the breathing dynamics of double-stranded DNA. We model the spontaneous formation of spatially localized openings of a damped and driven DNA chain, and find that linear instabilities lead to dynamic dimerization, while true local strand separations require a threshold amplitude mechanism. Based on our results we argue that a specific terahertz radiation exposure may significantly affect the natural dynamics of DNA, and thereby influence intricate molecular processes involved in gene expression and DNA replication.“[/quote]

 This in general could mean trouble for future generations. Deformities, reproduction problems, and even the risk of having cancers are all potential damages that could occur.
