WebSep 5, 2024 · Carbon-14 (c-14) is a radioactive form of carbon that occurs in nature and is also newly formed in nuclear power processes. Carbon-14 is a health concern because it is released from nuclear power facilities as radioactive carbon dioxide and methane, traveling readily in the local and global environment. WebDec 7, 2015 · We call it carbon-14 because the total number of protons and neutrons in the nucleus, also known as the mass number, adds up to 14 (6+8=14). If we wanted to abbreviate the name of an isotope, we’d use the elemental symbol and the mass number, so carbon-14 would be abbreviated C-14.
Carbon-14, C-14, C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
