Rad-X (Fallout: New Vegas)

Rad-X is a chem $$

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 create near-immunity to radiation, even at moderate medical skill levels.

Gameplay
Rad-X is reasonably common and can be used frequently. Like Stimpaks and RadAway, Rad-X is non-addictive, and its effectiveness is controlled by the Medicine skill. Taking multiple doses of Rad-X does not increase the total radiation resistance (the effects do not stack). Instead, the drug's active time is lengthened (the effective time stacks).
