For inorganic materials, such as rocks containing the radioactive isotope rubidium, the amount of the isotope in the object is compared to the amount of the isotope's decay products (in this case strontium).

For example, by feeding plants carbon dioxide that contains the radioisotope carbon-14 and by monitoring the carbon compounds through the plants' life cycle, the intermediate stages of the photosynthetic process can be determined. Most natural radioisotopes are daughter isotopes, that is, products of the decay of Th.Isotope dilution is employed chiefly in analytical chemistry in situations in which precise quantitative analysis by conventional means is difficult.Certain kinds of geophysical investigations also require its use, as in determining the occurrence and distribution of trace elements in rock samples and meteorites.The energy produced by radioactivity has important military and industrial applications...... the branch of chemistry concerned with the chemistry of radioisotopes, elements, and substances, the laws governing the physicochemical behavior of this radioactive matter, the chemistry of nuclear transformations, and the physicochemical processes that accompany these transformations.radioactive isotopeor radioisotope,natural or artificially created isotope of a chemical element having an unstable nucleus that decays, emitting alpha, beta, or gamma rays until stability is reached...... Radiochemistry, because of the topics, methods, and objects of its investigations, can be subdivided into general radio-chemistry, the chemistry of nuclear transformations, the chemistry of radioactive elements, and applied radiochemistry.
