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.
Rad-X is best used in heavily irradiated areas. It 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).

Rad-X is commonly found in first aid kits scattered around the wasteland.
It can be bought from merchants that carry medicine.

↑Vault Dweller's Survival Guide p.5-18: "Rad-X is a preventive medication. Take Rad-X before exposure to radiation, and the total amount of radiation you receive will be reduced. Rad-X bolsters your bodies own Radiation Resistance. The stronger you are to start with, the more effective Rad-X will be."
↑Fallout Official Survival Guide p.124: "Rad-X: A radiation prophylactic. Use this drug before you enter a radioactive area, and the total amount of radiation you receive will be reduced. Rad-X increases your body's natural Radiation Resistance."
