What is radioactive dating of fossils and what isotopes are used

Short video description
Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods.

Radiometric dating - Wikipedia

Josh Fowler. Answers 2. Yair Frederick 5 October, 0. Carbon, the radioactive isotope of carbon used in carbon dating has a half-life of years, so it decays too fast. It can only be used to date fossils younger than about 75, years.

Radioactive Dating Age Of Fossils

Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and it can be used to date a wide range of natural and man-made materials. The best-known radiometric dating techniques include radiocarbon dating, potassium-argon dating, and uranium-lead dating.

Radioactive dating uses the decay rates of radioactive substances to measure absolute ages of rocks, minerals and carbon-based substances, according to How Stuff Works. Scientists know how quickly radioactive isotopes decay into other elements over thousands, millions and even billions of years. Scientists calculate ages by measuring how much of the isotope remains in the substance. The key to an age of a substance is the decay-product ratio. The ratio of the original isotope and its decay product determines how many half-lives have occurred since the sample formed.
