Airport body scanners and DNA

Airplane travel may soon become a whole lot more dangerous as more airports install whole body imaging equipment.

There have been no long-term safety tests of millimeter wave scanners. A study conducted at the Los Alamos National Laboratory showed that terahertz waves which are above the frequency of millimeter waves used in these machines could “..unzip double-stranded DNA, creating bubbles… that could significantly interfere with processes such as gene expression and DNA replication.”

According to, “…a new generation of cameras are set to appear that not only record terahertz waves but also bombard us with them. And if our exposure is set to increase, the question that urgently needs answering is what level of terahertz exposure is safe.” No one knows, yet security officials are asking you to walk into them.

Some of us may remember that in the 1950s shoe stores sometimes had X-ray machines for checking shoe fit. We now shudder that the public could be so ill informed. Yet here we are, 60 years later, allowing machines that have never been approved as safe for humans, have no FDA approval, be used to scan our bodies for the sake of “public safety.”
