Question

Why doesn't Carbon-12 decay as Carbon-14 does after an organism dies?

Answer 1

Carbon is found in different forms in the environment – mainly in the stable form of carbon-12 and the unstable form of carbon-14. ... Carbon-14 has a half life of 5730 years, meaning that 5730 years after an organism dies, half of its carbon-14 atoms have decayed to nitrogen atoms.
