Miners underground get exposed to a lot dust particles and radioactive radon gas (even miners in non-uranium mines, like underground coal mining). There is a lot of uranium underground, which over time decays to radon gas.

Coal dust and crystalline silica dust from underground mining causes long term damage to lungs:

For uranium mining a lot more stricter radon monitoring and air ventilation has been implemented in recent decades.
