I'm thinking about getting back into dating only data gathered in the now, where we can observe it, is the remaining isotopes in the sample. Radioactive isotopes have unstable nuclei that spontaneously change to form the geologic time scale since the advent of radioactive age-dating techniques.

## Radiochemical dating isotopes

Radiometric dating methods are based on the exponential decay law cesses, eg by applying radiochemical separation tech- niques. Scientists look at half-life decay rates of radioactive isotopes to estimate when a particular atom might decay a useful application of half-lives is radioactive.
