Radioactive uranium decays in a series of steps. Lead is the stable element at the end. So even if the ore originally contained no lead, the radioactive uranium isotopes in the ore will decay and become lead over time. Granted it takes a long time to do that, but it will eventually become lead. That's why uranium ores contain lead. It's the left over after the radioactive uranium isotopes have completed their decay.

Isotopes of Uranium will continue to radioactively decay until reaching a stable state. One of those isotopes decay to lead.

uranium is a radioactive element and if it is not controlled, it can cause great damages. on trhe other way, lead is used to control radioactivity. lead absorbs radioacctive radiations and exposes them. so to control uranium, lead is found in uranium.

That's what radioactive uranium breaks down into.

Because that is the final stage of the conversion after all the power has been exhausted.
