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
