Are There Dangers to DNA With Terahertz Waves Radiation and Scanners?

I have seen some of the photos of the Terahertz waves scanners, similar to xrays but supposedly only penetrates the surface materials... Unsettling is that new research indicates that the damage to dna strands may be subtle yet potentially of concern. My first thought is that the eyes should be shielded in any automated scanner.

The technology is still new and in the next decade or two we will know more about what the long term effects are.

How Terahertz Waves Tear Apart DNA

the forces that terahertz waves exert on double-stranded DNA are tiny, in certain circumstances resonant effects can unzip the DNA strands, tearing them apart. This creates bubbles in the strands that can significantly interfere with processes such as gene expression and DNA replication.
