According to the Oxford English Dictionary and the Webster Third New International Dictionary of the English Language "radiocarbon" refers to any radioactive isotope of carbon and hence has a more general sense than "carbon-14". They point out, however, that "radiocarbon" refers specifically to the carbon-14 isotope. All the other sources consulted do not make that distinction and give those terms as perfect synonyms, which, we feel, reflects the current usage. 8, record 1, English, - carbon%2D14

All living matter contains approximately one atom of Carbon 14 in every trillion stable atoms of Carbon. ... By measuring the proportion of radioactive to stable carbon, the point in time at which the incorporation of radioactive carbon ceased (i.e., the point of death) can be calculated. This carbon-dating process, as it is called, can be used to determine the age of anything derived from living matter as, for example, the age of wooden artifacts. 6, record 2, English, - carbon%2D14%20dating

La datation par le carbone 14 est la méthode la plus employée pour la détermination de l'âge d'échantillons d'origine animale ou végétale. [...] Après la mort de la plante ou de l'animal, la teneur en radiocarbone diminue selon la loi de désintégration radioactive [...] Mesurant donc l'activité spécifique d'un échantillon provenant d'un être mort il y a «t» années et en la comparant avec l'activité spécifique actuelle, on détermine «t» à l'aide [d'une] équation [...] 8, record 2, French, - datation%20par%20le%20carbone%2014

La technique de datation par le radiocarbone a été initiée par Willard Frank Libby de l'Université de Chicago dans les années 50. Libby a reçu le prix Nobel de chimie en 1960 pour la «Méthode d'utilisation du carbone 14 pour la détermination de l'âge en archéologie, géologie, géophysique et dans d'autres disciplines.» 6, record 2, French, - datation%20par%20le%20carbone%2014
