The idea of radiocarbon dating relied on the prepared assumption that when an organism died, it would be cut off from the carbon cycle, thus creating a time-capsule with a steadily diminishing carbon-14 rely. Living organisms from at present would have the identical quantity of carbon-14 as the ambiance, whereas extremely historic sources that have been as quickly as alive, corresponding to coal beds or petroleum, would have none left. For organic objects of intermediate ages—between a few centuries and a quantity of other millennia—an age could be estimated by measuring the amount of carbon-14 present within the pattern best site and comparing this in opposition to the recognized half-life of carbon-14. Several long tree-ring chronologies have been constructed specifically for use in calibrating the radiocarbon time scale. By radiocarbon relationship a piece of wooden which has been dated by counting the annual development rings of timber back to when that piece of wood grew, a calibration desk may be constructed to transform radiocarbon years to true calendar years.

One controversial example is the dating of a single layer of archaeology at the Bronze and Iron Age metropolis buried at Tel Rehov. By evaluating the two classes of carbon in organic remains, archaeologists can decide how recently the organism that left them final absorbed carbon-14 out of its environment.
