The key is to measure an isotope that has had time to decay a measurable amount, but not so much as to only leave a trace remaining.Given isotopes are useful for dating over a range from a fraction of their half life to about four or five times their half life.Another limitation is that carbon-14 can only tell you when something was last alive, not when it was used.A limitation with all forms of radiometric dating is that they depend on the presence of certain elements in the substance to be dated.It suffers from the problem that rubidium and strontium are very mobile and may easily enter rocks at a much later date to that of formation.

This is frequently because the selected technique is used outside of its appropriate range, for example on very recent lavas. The Institute for Creation Research's RATE project aimed to show scientifically that methods of radiometric dating produced wildly inconsistent and incorrect values.Although the time at which any individual atom will decay cannot be forecast, the time in which any given percentage of a sample will decay can be calculated to varying degrees of accuracy.
