Because the end products of uranium decays series are stable isotopes of lead.
All the isotopes from the decay chains exist in these rocks. The most important are the dangerous isotopes of radium and radon.
uranium can be found in rocks especially sandstone and underground
[Radon_is_found_in_all_kinds_of_rocks_everywhere]Radon exist in rocks containing uranium or thorium.

Radon is a decay product of uranium, which is relatively common in the Earth's crust, but generally concentrated in ore-bearing rocks scattered around the world.
George W. Moore has written: 'Reconnaissance for uranium-bearing carbonaceous rocks in California and adjacent parts of Oregon and Nevada' -- subject(s): Coal, Uranium ores
All the isotopes from the decay chains exist in these rocks. The most important are the dangerous isotopes of radium and radon.
Radon exist in rocks containing uranium or thorium.
Uranium is present in approx. 220 rocks and minerals.
uranium can be found in rocks especially sandstone and underground
Uranium dating is very useful to evaluate the age of rocks and minerals.

would you use uranium-lead radiometric dating to finnd an igneous rocks age
