> Nuclear workers are limited to about 2000 millirem per year... so the approximately 52,000 millirem per year the astronauts would receive on a Mars mission is a problem.
The limits for nuclear workers are extraordinarily conservative, so it may not be as much of a problem as you'd think. Given the safety track record of manned spaceflight, the radiation is probably the least of your worries.
