Methods of dating artifacts

The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope.

Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope C.

The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.

Another absolute dating method is thermoluminescence, which dates the last time an item was heated.

By making multiple measurements (you need at least two for a date estimate) we can find out how much radiation the item was exposed to over the years and can get dating estimates related to when the item was last heated.

This method has the following restrictions: a) It cannot be used to date items many thousands of years old; b) it can only be used in non-organic materials; and c) the materials to be dated must have been heated to more than 350 degrees Celsius. All of the current dating methods are going through refinement.

By John Black Dr John (Ioannis) Syrigos initially began writing on Ancient Origins under the pen name John Black.

He is both a co-owner and co-founder of Ancient Origins.

Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.

Archaeologists are seeking an accurate dating technique, but this method is yet to be found.

Here we come to the question of how accurate the dates are that we currently have regarding the history of the human race and our planet.

No wonder, then, that so much effort has been devoted to developing increasingly sophisticated and precise methods for determining when events happened in the past.

In archaeology, dating techniques fall into two broad categories: chronometric (sometimes called “absolute”) and relative.

Chronometric dating techniques produce a specific chronological date or date range for some event in the past. Relative dating techniques, on the other hand, provide only the relative order in which events took place.
