Radioactive phosphorus is used in the estimation of the surface phosphate of apatite rock. Surface areas of these materials calculated from these estimates are smaller than those derived from gas‐adsorption methods. Less than 2.5% of the total phosphorus exists as surface phosphorus in the 100‐mesh size fraction of these materials.
