Proportion 1 becomes: Stated in words, this equation says that the rate at which a certain radioisotope disintegrates depends not only on how many atoms of that isotope are present but also on an intrinsic property of that isotope represented by λ, the so-called decay constant.Values of λ vary widely—from 10 is the time elapsed since time zero.Half-life is defined as the time period that must elapse in order to halve the initial number of radioactive atoms.The half-life and the decay constant are inversely proportional because rapidly decaying radioisotopes have a high decay constant but a short half-life.Likewise, the conditions that must be met to make the calculated age precise and meaningful are in themselves simple: 1. Different schemes have been developed to deal with the critical assumptions stated above.

Even though it is impossible to predict when a given policyholder will die, the company can count on paying off a certain number of beneficiaries every month.

The results are then tested for the internal consistency that can validate the assumptions.

In all cases, it is the obligation of the investigator making the determinations to include enough tests to indicate that the absolute age quoted is valid within the limits stated.

In short, the process of radioactive decay is immutable under all known conditions.

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.

To compensate for the loss of mass (and energy), the radioactive atom undergoes internal transformation and in most cases simply becomes an atom of a different chemical element.
