What isotopes are used for radioactive dating
Radiocarbon Dating Groundwater The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited.
Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes.

By knowing how much carbon 14 is left in a sample, the age of the organism when it died can be known.
It must be noted though that radiocarbon dating results indicate when the organism was alive but not when a material from that organism was used.

Liquid scintillation counting is another radiocarbon dating technique that was popular in the 1960s.
