Proof of carbon dating

Specifically, there are two types of carbon found in organic materials: carbon 12 (C-12) and carbon 14 (C-14).

At its most basic level, carbon dating is the method of determining the age of organic material by measuring the levels of carbon found in it.

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.

They arrived at this conclusion by comparing age estimates obtained using two different methods - analysis of radioactive carbon in a sample and determination of the ratio of uranium to thorium in the sample.

In some cases, the latter ratio appears to be a much more accurate gauge of age than the customary method of carbon dating, the scientists said.
