With the Atomic! perk, you are 25% faster and stronger whenever you're basking in the warm glow of radiation. Outside irradiated areas, your Action Points (AP) regenerate faster and faster the higher your level of radiation sickness becomes.— in-game description

Atomic! is a perk in the Fallout: New Vegas add-on Old World Blues.


  • Surrounding Rad level > 0, Run speed x1.25, Attack speed x1.25, DT +2, STR +2
  • Rad 200-400, AP regen x1.1
  • Rad 400-600, AP regen x1.2
  • Rad 600-800, AP regen x1.33
  • Rad 800-999, AP regen x1.5


  • When eating foods that have a Rad effect longer than one second (such as Coyote meat), the perk will activate. Eating multiple coyote steaks will stack the Rads duration, giving the player a lengthy speed boost if many are consumed.
  • The AP regen bonus synergizes well with Rad Child.
