Rad Resistance

Rad Resistance is a Fallout, Fallout 2, Fallout 3 and Fallout Tactics Perk.

Fallout, Fallout 2 and Fallout Tactics
You are better able to avoid radiation, and the bad effects radiation causes. Each level of this Perk will improve your Radiation Resistance by 10% (Fallout) or 15% (Fallout 2, Fallout Tactics).

Fallout 3
Rad Resistance allows you to -- what else? -- resist radiation. This perk grants an additional 25% to Radiation Resistance.

This stacks with Rad-X.

Added Radiation Resistance from The Pitt (DLC) may dwarf out the need for this perk, though PS3 users will see use, and so may PC + Xbox360 users, though only if they do not buy the DLC.
