Naturally occurring uranium is composed of three major isotopes, uranium-238 (99.2739–99.2752% natural abundance), uranium-235 (0.7198–0.7202%), and uranium-234 (0.0050–0.0059%). All three isotopes are radioactive (i.e., they are radioisotopes ), and the most abundant and stable is uranium … See more Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the See more Uranium-232 has a half-life of 68.9 years and is a side product in the thorium cycle. It has been cited as an obstacle to nuclear proliferation using U as the fissile material, because the intense gamma radiation emitted by Tl (a daughter of U, produced relatively quickly) … See more Uranium-234 is an isotope of uranium. In natural uranium and in uranium ore, U occurs as an indirect decay product of uranium-238, but it makes up only 0.0055% (55 parts per million) of the raw uranium because its half-life of just 245,500 years is only about … See more 1. ^ U – Excited nuclear isomer. 2. ^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits.

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.
