It provided a means by which the age of the Earth could be determined independently. Accurate radiometric dating generally requires that the parent has a long enough half-life that it will be present in significant amounts at the time of measurement except as described below under "Dating with short-lived extinct radionuclides" , the half-life of the parent is accurately known, and enough of the daughter product is produced to be accurately measured and distinguished from the initial amount of the daughter present in the material. Beta particles are products of radiocarbon decay. A relatively short-range dating technique is based on the decay of uranium into thorium, a substance with a half-life of about 80, years. Stanford, Calif. The additional samples allow errors such as background radiation and systematic errors in the laboratory setup to be detected and corrected for. Where are the data and age calculations that result in a consistent set of ages for all rocks on earth, as well as those from the moon and the meteorites, no greater than 10 years?
