Rad Regeneration

Rad Regeneration is a quest perk in Fallout 3.

Effects
When under the effects of Advanced Radiation Poisoning (400+ Rads) any crippled limbs will automatically regenerate.

This perk is gained by getting exposed to Critical Radiation Poisoning (600+ rads) for Moira's Wasteland Survival Guide. This mutation is a result of Moira's experimental radiation treatment.
