Radioactive dating disproved

other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.C14 is continually being created and decaying, leading to an equilibrium state in the atmosphere.When the carbon dioxide, containing C14 as well as stable C12 and C13, is taken in by plants it is no longer exposed to the intense cosmic ray bombardment in the upper atmosphere, so the carbon 14 isotope decays without being replenished.For example, the C14 concentration in the atmosphere depends upon cosmic ray intensity.To take this into account, a calibration curve is developed using other dating methods to establish the C14 levels over time.

After a long enough time the minority isotope is in an amount too small to be measured.

Argon/argon dating works using only the ratio of the concentration of the argon isotopes. For the purposes of this debate, "accurate" means that 95% of the dating errors are within 10% of the measured date, within the time span for which the isotope pair is utilized.
