This need not be a problem on the trip out and back. You just need to spin up the ship so that the outer rim has 1 g. This is where the crew would spend most of their time. Long term exposure to radiation is however a different matter, but no worse than experienced during long stays in the International Space Station? (BTW if I had my way, trips to Mars would take a few days, not months ;) Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
