What is radioactive carbon dating used for

For example, rootlet intrusion, soil type (e.g., limestone carbonates), and handling of the specimens in the field or lab (e.g., accidental introduction of tobacco ash, hair, or fibers) can all potentially affect the age of a sample.Bioturbation by crabs, rodents, and other animals can also cause samples to move between strata leading to age reversals. The Radiocarbon Revolution Since its development by Willard Libby in the 1940s, radiocarbon (14C) dating has become one of the most essential tools in archaeology.

This is a major concern for bone dates where pretreatment procedures must be employed to isolate protein or a specific amino acid such as hydroxyproline (known to occur almost exclusively in bone collagen) to ensure accurate age assessments of bone specimens.This process of decay occurs at a regular rate and can be measured.By comparing the amount of carbon 14 remaining in a sample with a modern standard, we can determine when the organism died, as for example, when a shellfish was collected or a tree cut down.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.

However, there are a number of other factors that can affect the amount of carbon present in a sample and how that information is interpreted by archaeologists.
