In the process of disintegration, the atom gives off radiation energy emitted in the form of waves. Hence the term radioactive decay. Each element decays at its own rate, unaffected by external physical conditions. By measuring the amount of original and transformed atoms in an object, scientists can determine the age of that object.

Invisible, high-energy particles that constantly bombard Earth from all directions in space. Also known as tree-ring dating, the science concerned with determining the age of trees by examining their growth rings. Measurement of the time it takes for one-half of a radioactive substance to decay. The predictable manner in which a population of atoms of a radioactive element spontaneously disintegrate over time.

Study of layers of rocks or the objects embedded within those layers. The age of the remains of plants, animals, and other organic material can be determined by measuring the amount of carbon contained in that material. Carbon, a radioactive form of the element carbon, is created in the atmosphere by cosmic rays invisible, high-energy particles that constantly bombard Earth from all directions in space. When carbon falls to Earth, it is absorbed by plants. These plants are eaten by animals who, in turn, are eaten by even larger animals.

Eventually, the entire ecosystem community of plants and animals of the planet, including humans, is filled with a concentration of carbon As long as an organism is alive, the supply of carbon is replenished. When the organism dies, the supply stops, and the carbon contained in the organism begins to spontaneously decay into nitrogen The time it takes for one-half of the carbon to decay a period called a half-life is 5, years.

By measuring the amount of carbon remaining, scientists can pinpoint the exact date of the organism's death. The range of conventional radiocarbon dating is 30, to 40, years. With sensitive instrumentation, this range can be extended to 70, years.

Mostly used to date pottery in archaeology the method is very effective but costly. The greatest problem with dating an artefact from an archaeology site is that nearly every absolute dating process requires the destruction of at least a piece of the object in conducting the analysis.

There are relatively few dating laboratories and having an artefact dated can be an expensive exercise especially if the artefact is not of great value itself. Dating Techniques In Archaeology.
