How dependable is geologic dating?

Robust crystals referred to as zircons, for instance, are long-lasting and current in many rocks. But excessive temperatures can drive lead, a daughter product of radioactive uranium and thorium, out of the crystal. Similarly,
What three issues have to be recognized to perform radiometric dating?
Some minerals in rocks and organic matter (e.g., wood, bones, and shells) can include radioactive isotopes. The abundances of mother or father and daughter isotopes in a sample could be 
measured and used to determine their age. This methodology is considered one of a household of strategies that use multiple, completely different unstable uranium isotopes that decay into stable lead isotopes by totally different chemical pathways. The most related for human evolution analysis is the decay pathway beginning with Uranium-238 (238U), which decays to Lead-206 (206Pb). Unlike the many other radioactive components, uranium requires multiple steps to decay into lead due to its massive atomic weight.
floor has little U238 and little U235 and doubtless little lead
