Radiocarbon dating biodiesel

Libby confirmed the accuracy of radiocarbon dating by comparing his results with the known age of tree ring samples.

Turnbull, a radiocarbon scientist at GNS Science, a geoscience consultancy in New Zealand, calls the result impressive.

When living things die, they stop incorporating carbon into their bodies, and their carbon-14 starts to decay away.

Scientists can calculate how long ago something died by measuring how much carbon-14 is in its remains.

I recently shared a story that included radiocarbon dating.

By happy coincidence, December 17 is the birthday of Willard Libby, the American chemist who invented it.
