Field procedures consisted of testing outcrops along roads, in cliffs, and around rim rocks, and testing mines, prospects and the dumps thereof with the appropriate instruments in an attempt to locate exposures of areas showing anomalous radioactivity and to ascertain the geological conditions under which such radioactivity occurred.
