Occupational Safety in Uranium Mining

The product of uranium mining is normally uranium oxide concentrate – U 3 O 8 – which is shipped from the mines in 200-litre drums. This is barely radioactive, but has chemical toxicity similar to lead, so occupational precautions are taken similar to those in a lead smelter. Most of the radioactivity from the ore ends up in the tailings.
