Daughter isotope of uranium
WebWhen an unstable Uranium (U) isotope decays, it turns into an isotope of the element Lead (Pb). We call the original, unstable isotope (Uranium) the "parent", and the product of decay (Lead) the "daughter". From careful physics and chemistry experiments, we know that parents turn into daughters at a very consistent, predictable rate. WebMany radioactive dating methods are based on minute additions of daughter products to a rock or mineral in which a considerable amount of daughter-type isotopes already …
