and probably hate it everytime someone is stupid enough not remove all the change from their pocket and force them to do a pat down.
And pat downs are just that. You are gonna be touched so word of warning.....don't go through the detector with something that sets it off and you will be just fine.
Some people are so concerned with being victims it get's old really quick.

It talks about some sort of "terahertz" wave detector to identify suicide bombs.
Not sure of the technical details, but it sounds interesting.

Safety
The terahertz region is between the radio frequency region and the optical region generally associated with lasers. Both the IEEE RF safety standard and the ANSI Laser safety standard 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 performed mathematical models how terahertz radiation 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". 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.
