The chief isotopes, carbon-12 and carbon-13, are not. However, carbon-14, a heavier isotope, is unstable and slowly decays, with a half-life of 5730 years. This makes it valuable to determine the age of fossils, by measuring their C-14 content.

Carbon is non-radioactive excepting the isotope carbon-14.
14 atoms of carbon.
The element is carbon and the isotope is 6C14
The element with 6 protons and 8 neutrons is carbon-14, which is a radioactive isotope of carbon.
Radiocarbon is another name for carbon 14, which is a weakly radioactive isotope of the element carbon.
Carbon-14
When a radioactive element decays, it releases energy in the form of radiation (such as alpha or beta particles). The decay changes the element into a different element or isotope, which may also be radioactive. This process continues until a stable non-radioactive element is formed.
The melting points of elements 104 to 118 are not firmly established but they are all solid at room temperature and so it is assumed that they melt at some temperature.Helium and carbon do not melt. Helium is not radioactive but carbon does have isotopes: C-13 and C-14 which are radioactive.
non radioactive element
The symbol for the radioactive isotope Carbon-14 is ^14C. The superscript 14 indicates the mass number of the isotope, which is the sum of protons and neutrons in the nucleus. The letter C represents the chemical element carbon.
In chemistry, a parent element is a radioactive element that undergoes decay to form a different element known as the daughter element. The parent element gives rise to the daughter element as a result of radioactive decay processes such as alpha decay, beta decay, or electron capture. The daughter element has a different number of protons and atomic number compared to the parent element.
