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.

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

The astronomical community need to start acknowledging jet aircraft contrails to be the problem that they really are!

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.

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