The decontamination arch is a world object in the Fallout 4 add-on Wasteland Workshop.


The decontamination arch is a settlement object that, when powered and switched on, removes all radiation from the player character when they pass through it. It can be constructed at any friendly settlement, and requires two units of power to function. Its built-in switch[1] can be used to activate and deactivate it, so it does not require an external switch.
