Rad-X is a chem in Fallout, Fallout 2, Fallout 3 and Fallout Tactics.

It's an anti-radiation chem to be taken before exposure (unlike Rad Away, which removes the effects of radiation after a person gets irradiated).

Fallout 3
Rad-X is an anti-radiation chemical that can significantly reduce the danger of irradiated areas. When combined with an Advanced Radiation Suit, Rad-X can—even at moderate medical skill levels—create near-immunity to radiation.

In general, Rad-X is best used in heavily irradiated areas, as that is where the most benefit can be seen. It is reasonably common and, as such, it can be frequently used as the situation warrants. Plus, like Stimpaks and Rad-Away, you cannot develop an addiction to Rad-X. However, taking multiple doses of Rad-X is pointless as it does not increase your resistance to radiation any further. (In other words, the effects do not stack with multiple doses of Rad-X.)

Appearances
