Has radiometric dating ever been wrong

If the earth is 4.6 billion years old however, there would have been plenty of time for most of the helium from such a long history of radioactive decay to escape from the granite rock formations where alpha-emitting Uranium is found.

Helium can soak through solid rock, but not very quickly.An alpha particle is made of two neutrons and two protons stuck together.This is the same thing as the nucleus of an atom of Helium gas.What this belief requires, is that the rock sample has remained undisturbed by anything that could have affected its decay rate or parent isotope amount or daughter isotope amount – for billions of years. As a matter of fact, it would be a sure bet that something did disturb the sample, if it sat there in the rock layers, waiting three billion years to be dug up by a modern-day researcher.Earthquakes nearby, magma chambers getting too close, ground water leaking into the layer or out of the layer, chemical changes, dissolving of isotopes, or crystallization of incoming isotopes – are all examples of things that could easily happen to a rock sample underground, in only a matter of centuries, not necessarily millennia nor eons of time.
