Half-life and carbon dating
How Does Carbon Dating Work Carbon-14 is a weakly radioactive isotope of Carbon; also known as radiocarbon, it radiactive an isotopic chronometer. C-14 dating is only applicable to organic and some inorganic materials not applicable to metals. Gas proportional counting, liquid scintillation counting and accelerator mass spectrometry are the three principal radiocarbon dating methods. What is Radiocarbon Dating? These radioactive isotopes are unstable, decaying over time at a predictable rate. As the isotopes decay, they give off particles from their nucleus and become a different isotope. The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay.
isotope used for radioactive dating
Carbon-14 Dating Most everyone has heard of Carbon dating on the news or elsewhere sometime in the past years. In this article I hope to explain the theoretical and physical science behind Carbon dating, and discuss how it affects our lives and the validity of the process.

Exponential decay and semi-log plots Video transcript SAL. In the last video we saw all sorts of different types of isotopes of atoms experiencing radioactive decay and turning into other atoms or releasing different types of particles. But the question is, when does an atom or nucleus decide to decay?
