This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings.The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.Once you heat this item again using high temperatures, the trapped electrons become excited and recombine with the item’s material.This process frees energy in the form of light, which can be measured.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.
