I found several good sources, but none that seemed both complete enough to stand alone and simple enough for a What is radiometric dating?Simply stated, radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock.' It relies on three basic rules, plus a couple of critical assumptions.

Radiometric dating methods are the strongest direct evidence that geologists have for the age of the Earth.

All these methods point to Earth being very, very old -- several billions of years old.

Thus, an atom of carbon-14 (C14), atomic number 6, emits a beta particle and becomes an atom of nitrogen-14 (N14), atomic number 7.

A third, very rare type of radioactive decay is called electron absorption.

The half-life of a radioactive nuclide is defined as the time it takes half of a sample of the element to decay.
