What isotopes are used for radioactive dating

Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay.

A useful application of half-lives is radioactive dating.

Many rocks and organisms contain radioactive isotopes, such as U-235 and C-14.

The realisation that radioactive materials emit rays indicated a constant change of those materials from one element to another.

It might take a millisecond, or it might take a century. But if you have a large enough sample, a pattern begins to emerge.
