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. WebDaughter isotope determinations from the two decay systems may also be combined to calculate a 207 Pb- 206 Pb date in concert with an assumed or measured present-day 238 U/ 235 U ratio.
