RadAway

Rad Away is a chemical solution that bonds with radiation particles and passes them through your system. Takes time to work. It is also a potent diarrhetic. While Rad Away removes the negative effects of radiation, it does not prevent you from becoming irradiated, unlike Rad-X.

Fallout 3
In Fallout 3, Rad Away appears to no longer have the possibility to addict you to it, or it at least has a much smaller rate. Whether this is due to game redesign or if in fact this is a different variant due to locale differences is undetermined.
