Fluorine absorption Nitrogen dating Obsidian hydration Seriation Stratigraphy. 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. We know that elements can exist as isotopes, which means that their atomic nuclei contain the same number of protons but different numbers of neutrons.

The measurement of the daughter-to-parent ratio must be accurate because uncertainty in this ratio contributes directly to uncertainty in the age. Radiometric dating is a method used to determine the age of rocks and other materials based on the rate of radioactive decay. Learn about three. A gamma ray is a high-energy photon, and you have experienced gamma rays if you ever had an x-ray taken.
