Nuclear methods of dating

Identification of the chemical composition of such materials can give information on production sites and techniques, trade habits, and provide insight into socio-economic relationships.This book details the results of the Co-ordinated Research Project initiated by the International Atomic Energy Agency, Vienna with the assistance of the Smithsonian Institution, Washington, USA to introduce the principles of archaeo-chemical fingerprinting and foster the application of nuclear analytical methods to archaeological investigations by application of validated Instrumental Neutron Activation Analysis (INAA) to pottery samples.The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.The boat of a pharaoh was discovered in a sealed crypt and reassembled in a museum near the pyramids (see Fig. The age of our galaxy and earth also can be estimated using radioactive dating.

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.

Subsequently new crustal rocks formed via partial melts from the mantle.

U decay in those rocks added daughter Pb isotopes to the common or initial Pb isotopes in them, inherited from the rock’s sources.

Using the decays of uranium and thorium, our galaxy has been found to be between 10 and 20 billion years old and the earth has been found to be 4.6 billion years old. Within experimental error, this estimate agrees with the 15 billion year estimate of the age of the Universe.

Pre-Hispanic pottery has long been a focal point of archaeological investigations in Latin American countries.
