Yeah, most of the Mars missions planned are around 900 days round trip, around 500 of which will be on Mars waiting for the next transfer window. All of them include the astronauts being well shielded from radiation.
Too bad they'll be irradiated for months on the way there and back. We don't have the technology to completely shield against that, yet. And no, we can't use water, or lead, the amount needed would be way too heavy.
This is a trust fund sperglord's pipe dream.
