Alright you guys...quit talking out your a@@.
It is quite likely that there would be little or no ill effects from exposure to the 2Sv chronic dose you would receive in the typical Mars mission.
Easy there, stud - a$$ talking is a core competence in the intel world.... :icon_tong
Without delving too deeply into the geekery here, there is great uncertainty in what the actual dose on a nominal 400 day Mars mission would be. That's because we don't have a lot of data on cosmic ray or solar proton exposures in interplantetary space. It might be ok, it might be really bad - there's just not enough data to accurately forecast. (For what it's worth, I've seen some of the more pessimistic estimates, especially those that assume a major coronal mass ejection / solar proton event during the flight.) The estimates matter a lot, too, since shielding is heavy, and heavy = big $$ in space. Also, cosmic rays love to blow through even heavy shielding.
The bottom line? You won't likely won't get literally fried, but you would get lots more radiation than anyone is really comfortable with. Would people volunteer for a mission even with an increased cancer risk or other adverse health effects? I'm sure they would, but I'm not sure the policy powers-that-be would be comfortable sending people into such an environment, even for a noble cause. To make Mars a reality, we either need to figure out how to a) get there much faster, b) come up with lightweight but effective shielding, or c) send people and just accept the risks. Alternatively, just send the robots and have someone jam the stupid Mars TALL KINGs....

Otherwise, go to Google and type "Midget Lesbians" and you will have plenty of alternative amusements...
p.s. Scoob - your rad hardness is way above mine! 2 Sv, even as a chronic dose, is a lotta juice.
