what isotope of carbon is used for radioactive carbon dating-59

It is clear that carbon-14 dates lack the accuracy that traditional historians would like to have.

There may come a time when all radiocarbon ages rest on firmer knowledge of the sample’s original carbon-14 level than is now available.

Whenever the number of cosmic rays in the atmosphere is low, the rate of carbon-14 production is correspondingly low, resulting in a decrease of the radioisotope in the carbon-exchange reservoir described above.

Studies have revealed that the atmospheric radiocarbon level prior to 1000 it was about 8 percent above what it is today.

Since Libby’s foundational studies, tens of thousands of carbon-14 measurements of natural materials have been made.
