What is measured in the radiocarbon dating of organic

In brief, radiocarbon dating measures the amount of radioactive carbon 14 (14C) in a sample. When a biological organism dies, the radioactive carbon in its body begins to break down or decay. This process of decay occurs at a regular rate and can be measured. ...read more


What is measured in the radioactive dating of organic

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.[1] ...read more
