39 Cook noted that, in ores from the Katanga mine, for example, there was an abundance of lead-208, a stable isotope, but no Thorium-232 as a source for lead-208.

Once something dies, it ceases taking in new carbon-14, and the existing carbon-14 within the organism decays into nitrogen at a fixed rate.Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods.Relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object.The object's approximate age can then be figured out using the known rate of decay of the isotope.For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms.
