Environmental impact of phosphate mining and

The radioactivity of phosphate rock was probably first observed in 1908, when the British physicist R. Strutt found that samples of phosphorite were many times more radioactive than the average rocks of the Earth's crust. 23 The dominant radioactivity detected in phosphate rocks are uranium, thorium and their decay products in equilibrium with ...
