Radioisotope dating (also referred to as radiometric dating) is the process of estimating the age of rocks from the decay of their radioactive elements.

Since God is the Creator of all things (including science), and His Word is true (“), the true age of the earth must agree with His Word.

The methods work because radioactive elements are unstable, and they are always trying to move to a more stable state. This process by which an unstable atomic nucleus loses energy by releasing radiation is called radioactive decay.

The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.

The age of a rock can be calculated if its ratio of uranium to lead is known.

This is unstable and eventually decays to lead, which is stable.

U–Pb Decay System and Age Calculations The accumulation of Pb in U-bearing minerals according to known decay rates of radioactive parent isotopes of U and Th forms the basis of this dating method.
