Free Radical (perk)

 is a challenge 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.

Bugs

 * At least in hardcore mode this perk is not working. RadAway's description shows as effectivness being triples (-30 for 10 seconds instead of -10, using 41 Medicine), but effects list shows -10, not -30, and total of 100 radiation removed. This has been confirmed in multiple accounts, but it is unknown if it affects normal mode as well.
 * Didn't work for me in normal mode. I got three radaways in my inventory while in Camp Searchlight. First 3 did -75 and gave me the perk. The third then ALSO did only -75.
