Notes

  • Rad-X can be stacked. Each subsequent Rad-X that the Sole Survivor consumes will improve the Radiation Resistance with a further 100 points.
  • Taking Rad-X does not count as an affinity action as it can not cause addiction to the player, therefore not being checked as a chem, but rather as a healing item. Note that this does not apply to Med-X however.
