More Bad News for Radiometric Dating

Radioactive Dating. One of the most commonly used methods for determining the age of fossils is via radioactive dating (a.k.a. absolute dating) Types of Radioactive Decay. Half Life. Radioisotopes decay at a constant rate and the time taken for half the original radioisotope to decay is known as the half life.
