Difference between carbon dating and radiometric dating
Radiometric dating , radioactive dating or radioisotope dating is a technique used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed.The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
The method works best with material more than 1 My, with precisions in the ±1 My range (I've mostly been working on material in the 1.8 to 3.0 Gy range, ±1 My is a mind blowing degree of precision in this context).
Systems that have been exploited for radiometric dating have half-lives ranging from only about 10 years e.
However, in general, the half-life of a nuclide depends solely on its nuclear properties and is essentially a constant.
Radiometric dating is also used to date archaeological materials, including ancient artifacts.
Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms.
