Rad-X and Rad-X: diluted are consumable items in Fallout 76.


Rad-X is a medication used to temporarily increase Radiation Resistance. This is most useful when one does not have the added radiation protection from wearing a hazmat suit or power armor when entering areas with high levels of radiation, such as the blast zone from a nuke, fissure sites, or reactors in power plants around Appalachia.

It also reduces the radiation absorbed from irradiated enemies like feral ghouls, and reduces the chances of suffering a mutation if the radiation absorbed hits a certain level.

Rad-X temporarily suppresses all mutation effects, while diluted Rad-X will not suppress mutations.

Taking multiple doses of Rad-X or diluted Rad-X does not stack. Taking one while the other is active will simply replace the effect. This can be used to re-instate the benefits of mutations after the radiation protection from Rad-X is no longer needed, since taking diluted Rad-X will immediately replace Rad-X and thus restore the mutations.


While standard Rad-X cannot be crafted, it can be combined with Purified water to make the diluted version.
