Dating with radioactivity
WebWell, not really. There are many many isotopes which decay more slowly. The reason C-14 is used for dating is that due to its medium half-life (not long nor short), C-14 in the environment is in a state of homeostasis - constantly decaying and being renewed, such that the overall amount remains the same. WebSep 23, 2024 · Radioactive Dating. Radioactive dating is a process by which the approximate age of an object is determined through the use of certain radioactive nuclides. For example, carbon-14 has a half-life of 5,730 years and is used to measure the age of organic material. The ratio of carbon-14 to carbon-12 in living things remains constant …
