Flying in a modern jet airplane doses the human with levels of radiation comparable to those found in nuclear disaster zones.

If you have traveled on a jet airplane, then you have had a high powered radiation exposure that you have no genetic adaptation to.

As a sea level adapted human, I am more fearful about the radiation levels on top of high altitude mountains, mile high modern cities and inside jet aircraft than from nuclear reactors and bombs, as that is where I get the most radiation exposures in the modern world.

Very few people realize that the ionizing radiation levels on a commercial jet airplane at cruising altitude are approximately 28 times higher than ground level.

The Fukushima nuclear complex went on to become the worst man-made engineering disaster in all of human history, outside of war.

Go up in a big airplane. Go high enough, and you will see the radiation rainbow interference ring around the shadow of the airplane on the clouds below.
