It gives an accurate date, but only up to a certain age. HowStuffWorks Science Environmental Science Earth Science Geology Geologic Processes. Make graphene sheets from graphite flakes and cellophane tape.
The results were summarized in a paper in Science in , in which the authors commented that their results implied it would be possible to date materials containing carbon of organic origin. The advent of radiocarbon dating may even have led to better field methods in archaeology, since better data recording leads to firmer association of objects with the samples to be tested.
From about until , when atmospheric nuclear testing was banned, it is estimated that several tonnes of 14 C were created.
