Raw yellowcake flux is a consumable item in Fallout 76.


Raw yellowcake flux can be attained by harvesting flora in a recently nuked zone. Mutated variants of the flora will have name and color changes to indicate the mutation.[1] It can be consumed to quench thirst and provide a boost to Disease Resistance.

Raw flux decays rapidly into inert flux and must be stabilized at a chemistry station to be used for crafting. One exception to this is that raw yellowcake flux is used for crafting orbital strike beacons.


The following variants of flora produce raw yellowcake flux:

Name Produces Normal Mutated
Ash rose Rad rose
Wild blackberry Radberry
Bleach dogwood Gamma dogwood
Carrot flower Irradiroot
Soot flower Geiger blossom
Wild melon blossom Megaton melon blossom


Generally the color of the flora indicates the type of flux acquired. Exceptions include gamma dogwood that is blue and produces yellowcake flux and the Geiger blossom which is orange and green.
