Rubidium/strontium dating example for geologic dating, the age calculation must take into account the presence of the radioactive species at the beginning of the time interval if there is a non-radiogenic isotope of the daughter element present in the mineral, it can be used as a reference and the ratios of the parent and daughter elements plotted as ratios with that reference isotope.

Radioactive dating because the radioactive half-life of a given radioisotope is not affected by temperature, physical or chemical state, or any other influence of the environment outside the nucleus save direct particle interactions with the nucleus, then radioactive samples continue to decay at a predictable rate that is, any radioactive nucleus acts as a clock. Thermoluminescence dating, or tl dating, uses the fact that radioactive decays cause some electrons in a material to end up stuck in higher-energy orbits the number of electrons in higher-energy orbits accumulates as a material experiences more natural radioactivity over time.
