Free Radical (perk)

 is a perk in Fallout: New Vegas. You gain enhanced effects from Rad-Away.

Effects
Upon completion of this challenge, RadAway will now do three times its normal effect. This applies regardless of Hardcore mode being activated - in Hardcore mode, while RadAway will still reduce radiation over time (as opposed to all at once without Hardcore mode), the amount of radiation removed will still be three times its normal.

Note: This needs verification. Looks like it really improves RadAways effectiveness by +20% (mine went from -104 to -125 on xBox with current update).

Trivia

 * The name of this perk is a reference to atoms, molecules, or ions with unpaired electrons on an open shell configuration.
