The backscatter x-ray body scanners are the only scanners to be concerned with, that and improperly shielded luggage x-ray scanners you stand next to, which run at a much higher power level. The newer luggage scanners that do a CT scan are still using x-ray, it just spins around the luggage.
mmWave scanners use non-ionizing radio waves, in the same spectrum area as mmWave 5G, in fact, but at a much lower power level. Radio waves have over a century of evidence and science showing that non-ionizing radiation can’t mutate cells, which is necessary to cause cancer.
Ionizing radiation like x-rays, can. Likewise, flying in an airplane at an altitude above the protection of our atmosphere, and being exposed to the sun, also exposes one to ionizing radiation at much higher power levels. That being said, why would anyone trust humans in a mediocre security organization to properly maintain their machines? Especially now with the current admin gutting everything to the bone.
How about one better? Municipalities that ignore both safety and driver convenience in favor of feeling good about helping the environment, or so they perceive. The end result of more pollution, more hazardous navigational conditions for everyone, and more problems.
Example, a state law that made it so bicyclists no longer have to come to a stop at intersections. It was a feel-good measure to make things easier for bicyclists so they’re not having to come to a complete stop over and over. In implementation, it just means a car driving 55MPH comes up to a green traffic light intersection that would ordinarily be safe, except one of the cross-directions has trees blocking the side road, so a bike comes chugging down the hill at 35MPH and blazes through their red light right in front of the much heavier and slower to stop car. (C.R.S. § 42‑4‑1412.5)
Now, couple that with another law that allows large trucks, buses, and RVs preferential treatment at roundabouts. All other vehicles must yield to the large vehicle no matter what. And going back to… the bike doesn’t yield to anything. (C.R.S. § 42‑4‑715)
Welcome to Colorful Colorado.
People think the pandemic invited driver chaos, we were bold, and asked the universe, “hold my beer?”
