why does radioactive decay have to be constant in order for radiometric dating to be accurate

A relatively short-range dating technique is based on the decay of uranium into thorium, a substance with a half-life of about 80, years. B After 5 half-lives about 38 h , the remaining concentration of cis-platin will be as follows:. Because nuclear decay reactions follow first-order kinetics and have a rate constant that is independent of temperature and the chemical or physical environment, we can perform similar calculations using the half-lives of isotopes to estimate the ages of geological and archaeological artifacts. The negative sign indicates that N decreases as time increases, as the decay events follow one after another. Retrieved 19 May Analysis of a sample of charcoal from a fire in one such site gave a 14 C decay rate of 0. Simply by changing the neighboring atoms that are bonded to a radioactive isotope, we can change its half-life.
