Radioactive decay

Radiocarbon dating, also known as carbon-14 dating, is one of several methods referred to as absolute dating – but here’s an interesting fact. There is nothing...

In this activity, students model the radioactive decay process for carbon-14 by flipping coins. Each coin represents a carbon-14 atom, and if it lands tails up...

Associate Professor Fiona Petchey is using carbon-14 (C-14) to date artefacts of historical importance excavated from the Wairau Bar archaeological site in Blenheim.
