How do scientists use radiocarbon dating

WebOne of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains. This is a radiometric technique since it is based on radioactive decay. Cosmic radiation entering Earth's atmosphere produces carbon-14, and plants take in carbon-14 as they fix carbon dioxide.

21.4D: Carbon Dating and Estimating Fossil Age

WebJul 1, 2024 · Radiocarbon dating is the process of determining the age of a sample by examining the amount of 14 C remaining against its known half-life, 5,730 years. The reason this process works is because when organisms are alive, they are constantly replenishing their 14 C supply through respiration, providing them with a constant amount of the isotope.
