Does relative dating using radioactivity

Such checks include dating a series of ancient units with closely spaced but known relative ages and replicate analysis of different parts of the same rock body with samples collected at widely spaced localities.The importance of internal checks as well as interlaboratory comparisons becomes all the more apparent when one realizes that geochronology laboratories are limited in number.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 recognition that the rate of decay of any radioactive parent atom is proportional to the number of atoms ( Converting this proportion to an equation incorporates the additional observation that different radioisotopes have different disintegration rates even when the same number of atoms are observed undergoing decay.With This pair of equations states rigorously what might be assumed from intuition, that minerals formed at successively longer times in the past would have progressively higher daughter-to-parent ratios.This follows because, as each parent atom loses its identity with time, it reappears as a daughter atom. In short, one need only measure the ratio of the number of radioactive parent and daughter atoms present, and the time elapsed since the mineral or rock formed can be calculated, provided of course that the decay rate is known.Our editors will review what you’ve submitted and determine whether to revise the article.

The situation is analogous to the death rate among human populations insured by an insurance company.The results show that there is no known process that can alter the rate of radioactive decay.By way of explanation it can be noted that since the cause of the process lies deep within the atomic nucleus, external forces such as extreme heat and pressure have no effect.The same is true regarding gravitational, magnetic, and electric fields, as well as the chemical state in which the atom resides.In short, the process of radioactive decay is immutable under all known conditions.
