WebRadioactive decay is a spontaneous process in which an isotope (the parent) loses particles from its nucleus to form an isotope of a new element (the daughter). The rate of decay is conveniently expressed in terms of an isotope's half-life, or the time it takes for one-half of a particular radioactive isotope in a sample to decay. WebDec 17, 2024 · Zircon crystal age dating is conducted using the principals of radiometric dating. Basically, all radiometric dating techniques rely on measuring the ratio of two isotopes in a substance: the parent isotope which is radioactive and therefore unstable, and the stable daughter isotope which is the end product of the radioactive decay of the parent.
