again, radiation absorbed dose from cosmic rays is different from that radiation of solar flares and coronal mass ejections. Cosmic radiation has been decreasing over time. Even a Mars mission at solar minimum would not expose the astronauts to significantly more radiation than they would have in orbit http://www.srl.caltech.edu/ACE/ASC/DATA/bibliography/ICRC2005/usa-mewaldt-RA-abs1-sh35-oral.pdf http://www.srl.caltech.edu/ACE/ASC/DATA/bibliography/ICRC200... Solar flare activity can be as hazardous to commercial air passengers https://eos.org/research-spotlights/solar-flares-increase-radiation-risk-on-commercial-aircraft https://eos.org/research-spotlights/solar-flares-increase-ra... In any event, we truly live in the goldilocks zone where a balance of cosmic factors enable us to enjoy life. Yet we continue to do our best to screw it all up because we can only think of one thing at a time. We should do more to increase the earth's ability to tolerate us.
