Chemistry radioactive dating

01 Mar

It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and it can be used to date a wide range of natural and man-made materials.

If one knows how much of this radioactive material was present initially in the object (by determining how much of the material has decayed), and one knows the half-life of the material, one can deduce the age of the object.

Many of us believed that string theory was a very dramatic break with our previous notions of quantum theory.

There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon-12, carbon-13 and carbon-14.

In 1979, Desmond Clark said of the method “we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation” (3).

Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks.

Radiocarbon dating is one such type of radiometric dating.

A process for determining the age of an object by measuring the amount of a given radioactive material it contains.
