Radiometric dating vs radioactive dating

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.

It depends upon radioactive decay, which is known to be extremely stable, not influenced my chemical processes, and which can be measured quite accurately.Age estimates can be cross-tested by using different isotope pairs.Results from different techniques, often measured in rival labs, continually confirm each other.Other methods do not require knowing the initial quantities.For example, potassium decays into two different isotopes of argon having different half-lives.

C14 is continually being created and decaying, leading to an equilibrium state in the atmosphere.
