xXx Galleries Dating Rubidium-87 calculator radiometric Much of our understanding of the ancient history of our planet comes from radioisotope dating, a process where scientists calculate the amount of certain isotopes in a geological sample to determine how old it is. But according to new research out of North Carolina State University, a flaw in this widely-used technique may be skewing the results so samples seem much older than they really are. Radioisotope dating hinges on the fact that over time, certain radioactive isotopes will decay to form other isotopes: For example, rubidium decays into strontium, with a half-life of To estimate when a sample of rock formed, scientists first calculate the concentration of both rubidium and strontium in the sample, and then compare those to the concentration of strontium, as a kind of baseline. By calculating the ratios of rubidium to strontium, and strontium to strontium, a graph called an isochron is created, which scientists can then use to determine the age of a sample. The process works best on igneous rocks, and has been used to study Earthly and lunar formations for decades.
