'It's an efficient machine to destroy nuclear waste': nuclear …

The unnatural uranium-233 isotope is fissionable and, as almost all the thorium is converted to uranium-233, this nuclear reaction does not produce any potent, long-lived transuranic products. Another huge advantage is that the chain reaction requires an initiator material to begin fission, with the reaction ceasing immediately upon its removal.

Uranium–Lead, Zircon | SpringerLink

Zircon is the mineral most widely used for determining geological ages with the U–Pb system. The main reasons are (1) the incorporation of variable amounts of uranium, but essentially no lead, at the time of formation, so that virtually all the lead found in a grain of zircon today stems from the radioactive decay of uranium; (2) the very …
