Is Rad-X permanent?

No, the effects of Rad-X are temporary

Picture Rad-X like a shot of epinephrine—it jacks up your radiation resistance in a hurry, but the effect doesn’t last.

Take potassium iodide tablets, for example—they give you temporary protection during nuclear scares by blocking radioactive iodine in your thyroid gland FDA.

Mentats do not stack with themselves, but Party Time Mentats stack with regular Mentats

Bethesda’s balancing act at its finest. This design choice reflects the studio’s approach to keeping player agency in check while maintaining game balance Fallout Wiki.
