Evidence for accelerated decay
Helium retention in zircons
Recent Carbon 14 dates
Radiation and accelerated decay
Evidence of accelerated mutation rate
Evidence of a nearby supernova
Lack of objects in the Kuiper belt
Correlation between surface heat flow
and the radioactivity of surface rocks
It appears that decay was faster during the Flood.
This accelerated decay would have increased temperatures in the earths crust and may have caused the Flood.
