Geoff Bonning from the Australian National University (anu.edu.au) describes what radioisotopes are. This as part of a series of educational videos on Dating the Earth. 

This clip has been created by the Research School of Earth Sciences (rses.anu.edu.au). These resources are part of a comprehensive program, curriculum matched to the unit 'Introduction to Earth systems'.

This video touches on the following curriculum descriptors:
Precise dates can be assigned to points on the relative geological time scale using data derived from the decay of radioisotopes in rocks and minerals; this establishes an absolute time scale and places the age of the Earth at 4.5 billion years (ACSES017)
