Given below is the simple mathematical relationship that allows the time elapsed to be calculated from the measured parent/daughter ratio.
Likewise, the conditions that must be met to make the calculated age precise and meaningful are in themselves simple:isochron methods that make use of the rubidium-strontium or samarium-neodymium decay schemes, a series of rocks or minerals are chosen that can be assumed to have the same age and identical abundances of their initial isotopic ratios.
The results are then tested for the internal consistency that can validate the assumptions.
Although it is impossible to predict when a particular atom will change, given a sufficient number of atoms, the rate of their decay is found to be constant.
The situation is analogous to the death rate among human populations insured by an insurance company.
