The accompanying table shows the reduction of a quantity as a function of the number of half-lives elapsed.

Simulation of many identical atoms undergoing radioactive decay, starting with either 4 atoms per box (left) or 400 (right).

Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.

Dating is not necessary to demonstrate that evolution is a fact.

Chronological sequence is all that is really required.

Rutherford applied the principle of a radioactive element's half-life to studies of age determination of rocks by measuring the decay period of radium to lead-206.

Half-life is constant over the lifetime of an exponentially decaying quantity, and it is a characteristic unit for the exponential decay equation.
