The Origin of Earth’s Radioactivity

As the flood began, stresses in the massive fluttering crust generated huge piezoelectric voltages. For weeks, powerful electrical surges within Earth's crust–much like bolts of lightning–produced equally powerful magnetic forces that squeezed (according to Faraday's Law) atomic nuclei together into highly unstable, superheavy elements that quickly fissioned and decayed into subatomic particles and various isotopes, some of which were radioactive.
