Measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying atoms in the sample and not just the few that happen to decay during the measurements; it can therefore be used with much smaller samples (as small as individual plant seeds), and gives results much more quickly.

The development of radiocarbon dating has had a profound impact on archaeology.

The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age.

Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).

It becomes incorporated into the biomolecules of heterotrophic organisms (animals) via the food chain.Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.Because the time it takes to convert biological materials to fossil fuels is substantially longer than the time it takes for its in the atmosphere, which attained a maximum in about 1965 of almost twice what it had been before the testing began.The C14-L list is intended primarily for technical communication and is not an appropriate forum for uninformed debate over the premises or theological implications of dating methods, since talk.origins and other Usenet groups and Listserv lists already handle that function admirably.The listowner reserves the right to implement moderation if that charter stipulation is ignored.

Radiocarbon dating, also known as carbon-14 dating, is a radioactive decay-based method for determining the age of organic remains that lived within the past 50,000 years.
