    Wiki radiometric dating

    Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct.

    Carbon dating is used to work out the age of organic material — in effect, any living thing.

    It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities.

    A standard hydrogen-helium gas giant, Farcrothu is only distinguished by its moons; several dozen of them have been sculpted into the likenesses of an arthropodal alien race not yet known to Council science.

    Radiometric dating suggests the moons were worked over half a million years ago.

    Radiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method.

    It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old. Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.
