Barrel (Fallout 4)

Metal barrels are world objects in Fallout 4, and a settlement object in its add-on Wasteland Workshop.

Radioactive barrels
Radioactive barrels are yellow and white metal barrels with a radiation hazard notice printed on the side. A barrel can be scrapped into three units of acid and two of steel. The radioactive barrels emit high levels of radiation in a small area. Once they are scrapped, the area may remain contaminated for a few seconds before going down to background radiation.
