To be fair, the Fallout universe doesn’t follow real world physics. If it did, the world wouldn’t be a mostly barren wasteland. Plants don’t give a fuck about radiation; just look at Chernobyl.
There’s also the fact that they have nuclear-powered batteries that are still holding a charge, and many unmaintained buildings are still intact instead of being just giant piles of decomposing steel. (And obviously there wouldn’t be any mutant 2-headed oxen, giant cockroaches, super mutants, ghouls, etc.) The Fallout universe runs on 1950s sci-fi physics.
