You spend about half the time in your sleeping quarters and require rather little space there.
You could use your water tank and other supplies/equipment as shielding against radiation protecting you to nearly 100% for roughly 50% of the time.
Now during flight you can extend that by staying in bed longer and just going out for exercise, so 75-80% less radiation during transit.
On Mars you could potentialy build structures underground or cover them with huge quantities of sand/rocks/whatever you can find and cut down radiation exposure there to basicl, only when you are outside.
That way you would have cut down radiation exposure to a level that I would consider acceptable for a once in a lifetime mission of consenting adults.
Keep in mind that many people, including me, would accept getting exposed to radiation to a certain degree that raises our risk of cancer to a measureable degree for a mission like that.
To be honest, I've done stuff that was more likely of killing me than the expected radiation dose from such a mission.
