Radioactive Material From Fertilizer Production | US EPA
When processing phosphate rock to make fertilizer, the phosphorous is removed by dissolving the rock in an acidic solution. The waste that is left behind is called phosphogypsum. Most of the naturally-occurring uranium found in phosphate rock ends up in the acid and the other radionuclides, including radium, mostly end up in the waste.
