Potential radiological impacts from mining and processing are mainly due to the radiation associated with radionuclides 232 Th and 238 U and their decay products and there is a relatively small essentially negligible contribution to radiation dose estimates from 40 K in the bauxite. The approximate K chemical concentration of 0.2 wt in bauxite ore corresponds to a K-40 activity of 0.062
