Any effect of that won't be measurable. If you get that dose in one hour, you will show symptoms of Acute Radiation Syndrome and have about a 5% chance of dying from it in a month. Rate likely will have a different effect with cosmic radiation than with gamma, but a blanket statement that "rate of dosage doesn't matter" is just plain wrong.</div><div><br></div><div>I also said "take with a big grain of salt", not "disregard entirely". Heavy ion radiation is one of the two biggest medical concerns (the other being .38 g gravity effects). It is a serious issue, but like .38 g just about impossible to experiment with on earth. Even if there is an accelerator that can create cosmic ray energies (and there isn't), no one would tie it up for 2 or 3 years for one experiment. So they do the experiment that they can, not the one which they need. Very common, but the results are rarely definitive.</div><div><br></div><div>s</div><div><br></div><div> </div></div></div></div>
