The most serious health hazard associated with uranium mining is lung cancer due to inhaling uranium decay products. Uranium mill tailings contain radioactive materials, notably radium-226, and heavy metals (e.g., manganese and molybdenum) which can leach into groundwater.

If uranium is so radioactive, how is it mined? - Quora

Any isotope with half life over 100 thousand years is hardly radioactive at all. Even a full ton of U235 is hardly radioactive to the people near it, cause most radiation will be alpha particles which will be trapped inside the Uranium lattice itself and meet with their free electrons becoming Helium-4 atoms.
