Physics, Astronomy & Cosmology / What happens to radiation dose outside Earth's atmosphere?

I've heard somewhere that when you leave the Earth's atmosphere, there is a huge radiation which is enough to kill or severely damage us. To avoid it, we need a 6 metre thick wall of lead to shield us from the radiation.
So, I was wondering what is going on? Many astronomers have gone out to space just for a short while, and have left the Earth's atmosphere, then came back - or am I mistaken of these facts?
A rocket surely doesn't have a 6 metre thick lead wall? Or have I heard this radiation thing wrongly all from the beginning?
