this scheme has been refined to the point that the error margin in dates of rocks can be as low as less than two million years in two-and-a-half billion years. all the samples show loss of lead isotopes, but the intercept of the errorchron (straight line through the sample points) and the concordia (curve) shows the correct age of the rock.
the decay rate is referring to radioactive decay, which is the process by which an unstable atomic nucleus loses energy by releasing radiation.

stimulating these mineral grains using either light (optically stimulated luminescence or infrared stimulated luminescence dating) or heat (thermoluminescence dating) causes a luminescence signal to be emitted as the stored unstable electron energy is released, the intensity of which varies depending on the amount of radiation absorbed during burial and specific properties of the mineral.“he just made jokes and gave me funny little compliments.
