7.3: Radioactive Decay, Half life, and C-14 Dating

WebOther radiometric dating techniques are available for earlier periods. One of the most widely used is potassium–argon dating (K–Ar dating). Potassium-40 is a radioactive isotope of potassium that decays into argon-40. The half-life of potassium-40 is 1.3 billion years, far longer than that of carbon-14, allowing much older samples to be dated. WebRadioactive Dating Using Carbon-14. The radioactivity of carbon-14 provides a method for dating objects that were a part of a living organism.
