Based on these observations and the known rate of radioactive decay, they estimate the time it has taken for the daughter isotope to accumulate in the rock.

To make matters even worse for the claimed reliability of these radiometric dating methods, these same basalts that flowed from the top of the Canyon yield a samarium-neodymium age of about 916 million years,5 and a uranium-lead age of about 2.6 billion years!Yet the same uranium decay also produced abundant helium, but only 6,000 years worth of that helium was found to have leaked out of the tiny crystals. Not Billions (Master Books, Green Forest, Arkansas, 2005), pages 65–78.This means that the uranium must have decayed very rapidly over the same 6,000 years that the helium was leaking. The assumptions on which the radioactive dating is based are not only unprovable but plagued with problems.These basalts yield ages of up to 1 million years based on the amounts of potassium and argon isotopes in the rocks.But when we date the rocks using the rubidium and strontium isotopes, we get an age of 1.143 billion years.
