“millimeter wave technology, as implemented at airports, unzips the molecules of DNA in your body.”
That would depend on whether the scanner is active or passive. Active would irradiate your body with mm band energy, while passive just uses the normal background radiation. Do you know which ones the airports use? Really would like to know.
I do not know the answer to your question. I read scientific analysis online when these scanners were distributed to airports.
It was stated these machines unzip dna. Sure you can find those articles with some Googling.
We decided to avoid them by opting out and getting frisked. The TSA people get pretty upset when you opt out. We got there early and patiently smiled. Probably made them mad too, but we were chill.
Recently, we joined Global Entry - both to speed up customs and immigration lines (and it really does), as well as because the lines for Trusted Travelers use the old metal detectors. You keep your shoes on, stuff in pockets, computer in bag. Very fast.
Also, lines are always shorter. This may buy us time for more years without them trying to force us through mw scanners. No other country has bearded us through those things.
