Quite a lot. I don't have the figures handy, but if you have High Frontier, you can explore this for yourself: compare radiation in LEO (which is well within the magnetosphere) to radiation in High Earth Orbit (outside the magnetosphere). It makes quite a difference.
But yeah, nine meters of water would do the trick too!
