Oops: Backscatter x-ray machines "tear apart DNA" →

cyberpunk:

Though touted as completely safe because the level of radiation is so low, travelers have been nervous about the devices — and not just because it shows off a nice outline of their privates to the people manning the machines — but because they remain scared of the health problems they might propose.

Looks like a little healthy paranoia might have been a good thing. While the conventional wisdom has held that so-called “terahertz radiation,” upon which backscatter x-ray machines are based, is harmless because it doesn’t carry enough energy to do cellular or genetic damage, new research suggests that may be completely wrong.

Specifically, researchers have found that terahertz radiation may interfere directly with DNA. Although the force generated is small, the waves have been found to “unzip double-stranded DNA, creating bubbles in the double strand that could significantly interfere with processes such as gene expression and DNA replication.”
