Rad Resistant [Perk]

Rad Resistant is a perk in Fallout 4. Increase your natural resistance to radiation.


  • Exposure to the Wasteland has made you more resilient, instantly granting +10 Radiation Resistance.
  • You now have +20 Radiation Resistance. (Requirement: Level 13)
  • You now have +30 Radiation Resistance. (Requirement: Level 26)


Radiation is much more dangerous in Fallout 4 than in previous games. For every 10 rads you receive, you maximum Hit Points will be reduced by 1%. This means that with 500 rads, your Hit Points will be reduced by half. And with 1000 rads, your Hit Points will be reduced to zero, and you will die. This makes managing radiation levels far more important, and it also means you will need to be fully prepared when entering any high radiation area.

This perk will make exploration somewhat easier by minimizing the impact of most radioactive sources, including land based nuclear waste sites, and irradiated lakes and rivers. Radiation caused by the initial blast of car explosions, mini nukes, and lightning strikes is not affected. See Nuclear Strike for further details.
