For example, an object with a quarter of its original amount (2x1/2) should be roughly 11,460 years old.In all radiometric procedures there is a specific age range for when a technique can be used.

Protons and neutrons together are called nucleons, meaning particles that can appear in the atomic nucleus.

A nuclide of an element, also called an isotope of an element, is an atom of that element that has a specific number of nucleons.

In 1905, shortly after the discovery of radioactivity, the American chemist Bertram Boltwood suggested that lead is one of the disintegration products of uranium, in which case the older a uranium-bearing mineral the greater should be its proportional part of lead.

Analyzing specimens whose relative geologic ages were known, Boltwood found that the ratio of lead to uranium did indeed increase...

In radiometric dating, the decaying matter is called the parent isotope and the stable outcome of the decay is called the daughter product.

Since the half-life of carbon-14 is 5730 years, scientists can measure the age of a sample by determining how many times its original carbon-14 amount has been cut in half since the death of the organism.

The technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material is called radioactive dating.

Many isotopes have been studied, probing a wide range of time scales.

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.

This decentralised structure is enhanced by a large number of permanent institutions at local level – parishes, basic ecclesial communities, hospitals and authorised health centres, orphanages, centres for the disabled, parish charity committees, development committees – which enables keeping in touch with the people and adjustment of interventions on the ground.
