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 diuretic. While Rad Away removes the negative effects of radiation, it does not prevent you from becoming irradiated, unlike Rad-X.

Fallout, Fallout 2 and Fallout Tactics
In Fallout, Fallout 2 and Fallout Tactics, Rad Away can be addictive.

Fallout 3
In Fallout 3, Rad Away is no longer addictive. This item can look a bit like a blood pack and is found in almost every medical and sceince facility and can often be found in first aid kits that hang on walls or are kept on shelves. It is not to be used to keep away radiation when entering radioactive areas like Rad-X but rather to be used after to rid youself of radiation diseases.

Appearances
Rad Away appears in all Fallout games.
