As long as you stay near the Earth (the moon is close enough), our magnetosphere will protect you from radiation.

When you get interplanetary, like on a trip to Mars, radiation exposure becomes arguable the most difficult problem to solve.

> The Mars Radiation Environment Experiment (MARIE) was launched in 2001 in order to collect more data. Estimates are that humans unshielded in interplanetary space would receive annually roughly 400 to 900 mSv (compared to 2.4 mSv on Earth) and that a Mars mission (12 months in flight and 18 months on Mars) might expose shielded astronauts to roughly 500 to 1000 mSv.
