I wonder if at least some volcanos might be radioactive ? The stuff is comming from deep below & there are theories the core is being kept molten thanks to decay of radioactive elements, so I wonder if some of that might get up occasionally ? Or is that nonsense as core is much much deeper and there is hardly any mixibg goin on between the layers?
