Is carbon dating accuracy
In order for carbon dating to be accurate, we must know what the ratio of carbon-12 to carbon-14 was in the environment in which our specimen lived during its lifetime.
during the industrial revolution more carbon-12 was being produced offsetting the ratio a bit).
Unfortunately the ratio of carbon-12 to carbon-14 has yet to reach a state of equilibrium in our atmosphere; there is more carbon-14 in the air today than there was thousands of years ago.

We thank you in advance for partnering with us in this small but significant way. All methods of radioactive dating rely on three assumptions that may not necessarily be true: It is assumed that the rate of decay has remained constant over time.
Since protons and neutrons weigh about the same, the atomic mass of ordinary carbon is 6 6 = 12.
It is called "Carbon-12," which is abbreviated "C." The fact that the atom has six protons is what makes it carbon.
