Graph of radiocarbon dating
This dating service provides support for all stages of radiocarbon dating from project design and sample choice right through to data analysis.
Calibration is not only done before an analysis but also on analytical results as in the case of radiocarbon dating—an analytical method that identifies the age of a material that once formed part of the biosphere by determining its carbon-14 content and tracing its age by its radioactive decay.
It should be noted that a BP notation is also used in other dating techniques but is defined differently, as in the case of thermoluminescence dating wherein BP is defined as AD 1980.
In later years, the use of accelerator mass spectrometers and the introduction of high-precision carbon dating have also generated calibration curves.Carbon consists of 99% carbon-12, 1% carbon-13, and about one part per million carbon-14.
