“In fact the body may be more able to repair the damage from cosmic rays than a REM equivalent of x-rays, or terahertz radiation.”
Or both or all may cause hormesis.
For now I’ll go with what the health physics guys say about dose and its measurement, when comparing 15 KeV photons to the flight environment.
I’ve seen some flight spectra, there are loads of photons, from air interaction and also from the mass of the plane. I’m more concerned with the neutron flux (for NSEU, not human effects), though at a bit higher altitude.
Where are the health physics studies on the back-scatter x-rays and the terahertz today? They are, I suspect, the same place we were during the Manhattan Project, that is just guesses with few real data points. But unlike the Manhattan Project where very few were subjected to these novel forms of radiation, we are here exposing the whole damn country.
That’s dangerous.
