Security 'Experts' Unveil New Terahertz Radiation Crowd Scanning Device To Keep You 'Safe'                                                        
A sensor that can scan huge crowds has undergone official tests. The revolutionary gadget -- similar to airport scanners but top secret -- is believed to silently analyze materials using the unique "terahertz" waves emitted by different substances. Government scientists began testing it a year ago on mock crowds. Now it's ready for you.

What IsTerahertz Radiation?
The terahertz region is between the radio frequency region and the optical region generally associated with lasers. Both the IEEE RF safety standard[8] and the ANSI Laser safety standard[9] have limits into the terahertz region, but both safety limits are based on extrapolation. It is expected that effects on tissues are thermal in nature and, therefore, predictable by conventional thermal models. Research is underway to collect data to populate this region of the spectrum and validate safety limits. 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[10][11] performed mathematical models how terahertz radiation interact with double-stranded DNA, which showed that nonlinear 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.  No problem,because our rotten government doesn't care if you get cancer or birth defects, as long as their friends get rich building deathrays while maintaining a tight control over the population.
