This allows the dating of much older and smaller samples but at a far higher cost.

In the example below, the bone must date to sometime between 1.75 and 1.5 million years ago.

For instance, a date of 100,000 5,000 years ago means that there is a high probability the date is in the range of 95,000 and 105,000 years ago and most likely is around 100,000.

decay or the rate of other cumulative changes in atoms resulting from radioactivity. The various isotopes of the same element differ in terms of atomic mass but have the same atomic number..

One half-life is the amount of time required for of the original atoms in a sample to decay.
