From The Vault
Radiation Resistance is a derived statistic in Fallout, Fallout 2, Fallout 3 and Fallout Tactics: Brotherhood of Steel.
The amount of radiation you are exposed to is reduced by this percentage. Radiation Resistance can be modified by the type of armor worn and anti-radiation chems. Rad-X temporarily increases Radiation Resistance.
[edit] Fallout and Fallout 2
Initial Level: Starting radiation resistance is equal to EN x 2. Average characters will have a 10% radiation resistance.
- The Fast Metabolism trait sets initial radiation resistance to 0.
- The Rad Resistance perk increases radiation resistance by 15% per rank. (10% per rank in FO1)
- The Vault City Inoculations perk increases radiation resistance by 10%.
- Rad-X temporarily increases radiation resistance by 50%. Half of it is lost after 24 hours, with resistance returning to it's original value after another 24 hours.
- In Fallout, rad resitance can go as high as 100% (needed to survive the Glow). In Fallout 2 however, it is capped at 95%.
[edit] Fallout 3
[edit] Permanently increasing Radiation Resistance
- The formula for radiation Resistance is (Endurance-1)*2. Each point of Endurance increases your Radiation Resistance up to a maximum of +18% at 10 Endurance.
- The Cyborg perk gives +10% Radiation Resistance.
- The Rad Resistance perk gives +25% Radiation resistance.
- The Survival Expert perk gives between +2% and +6% Radiation resistance.
- The Pitt Fighter perk from The Pitt gives +3% Radiation Resistance.
- The Booster Shot perk from The Pitt gives +10% Radiation Resistance.
[edit] Temporarily increasing Radiation Resistance
- The Rad-X drug gives up to +75% Radiation resistance with the Medicine skill at 100.
- A Radiation Suit increases radiation resistance while worn.
The maximum amount of resistance you can gain from perks and Endurance in Fallout 3 is 72% in total. You can increase this up to a maximum of 85% with items or drugs.
