Unlike other chat sites, you don't have to wait for Stranger to respond.There are also trace amounts of the unstable radioisotope carbon-14 (14C) on Earth.Raw (i.e., uncalibrated) radiocarbon ages are usually reported in radiocarbon years "Before Present" (BP), with "present" defined as CE 1950.The technique of radiocarbon dating was developed by Willard Libby and his colleagues at the University of Chicago in 1949.Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.Libby estimated that the steady-state radioactivity concentration of exchangeable carbon-14 would be about 14 disintegrations per minute (dpm) per gram.
