If you see a mushroom cloud from an atomic bomb, you’re supposed to stick your arm out and hold your thumb over the cloud. If the cloud is larger than your thumb, you’re in the radiation zone and should evacuate. This is what Vault Boy is doing in the Fallout series.
*Handy rule of thumb there

I guess it works as a rule of thumb, but I still don’t think that its what vault boy is doing
It’s a “rule of thumb” kinda deal you know? It’s meant more so if you see a mushroom cloud in the distance to determine...
interesting but i feel like an easier solution is “get the fuck away from any mushroom cloud you happen to see”
