What is radiocarbon dating used for

Marine20 - the marine radiocarbon age calibration curve (0–55,000 cal BP). SHCal20 southern hemisphere calibration, 0–55,000 years cal BP. The IntCal20 northern hemisphere radiocarbon age calibration curve (0–55 cal kBP). Applications of accelerator mass spectrometry. A detailed 2-year record of atmospheric (CO)-C-14 in the temperate northern hemisphere.

Age determination by radiocarbon content - world-wide assay of natural radiocarbon. Age determinations by radiocarbon content - checks with samples of known age. Natural radiocarbon from cosmic radiation.
