Methods of dating artifacts
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.
Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.
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.
This method includes carbon dating and thermoluminescence.
The absolute dating method first appeared in 1907 with Lord Rutherford and Professor Boltwood at Yale University, but wasn’t accepted until the 1950s.
It is the only method that can be used to date rocks, pottery and minerals for dates that are approximately between 300 to 10,000 years old.
This method is based on the fact that when a material is heated or exposed to sunlight, electrons are released and some of them are trapped inside the item.
