Carbon-14 has a half-life of 5730 years, meaning that the amount of carbon-14 in a sample is halved over the course of 5730 years due to radioactive decay.

Such raw ages can be calibrated to give calendar dates.Among others, all the tree ring samples used for the calibration curves (see below) were determined by these counting techniques.Such decay counting, however, is relatively insensitive and subject to large statistical uncertainties for small samples.These raw dates are also based on a slightly-off historic value for the radiocarbon half-life.Such value is used for consistency with earlier published dates (see "Radiocarbon half-life" below).
