Rad Absorption (Fallout: New Vegas)

Rad Absorption is a perk

Effects
This perk remains functionally identical to the one in Fallout 3. However, Irradiated Beauty exists as a possible alternative.

This perk does not remove rads fast enough to serve as an effective defense against radioactive environments. However, it is useful in preventing the "death from a thousand paper cuts" rad build up, which combined with a high radiation resistance can reduce incidences of serious radiation poisoning to few and far between. It is especially useful in hardcore mode as it effectively eliminates the slow but steady buildup of rads from most food and water.
