What is Radioactive Dating? - Definition & Facts
Additionally, elements may exist in different isotopeswith each isotope of an element differing in the number of neutrons in the nucleus. The trapped charge accumulates over time at a rate determined by the amount of background radiation at the location where the sample was buried. By measuring the decay products of extinct radionuclides with a mass spectrometer and using isochronplots, it is possible to determine relative ages of different events in the early history of the solar system. Cell Division: Holt McDougal Earth Science: He converted the carbon in his sample to lamp black soot and coated the inner surface of a cylinder with it.
