• Non-destructive instrumental neutron activation analysis was examined. Using long-lived isotopes, La, Sm, Ce, Sc, Fe, Co, Cs, Th, Cr, Hf, and Tb, and using short-lived isotopes, Al, V, Na, and Mn in various particle size fractions of clay, silt, fine sand, and coarse sand, and the oxalic acid extracts of the soil were determined. Relative standard deviations (CV) were in the range of 1.7 to 12%. The reliability of the analysis was also examined. Recovery percentages were in the range of 87 to 120%. The analytical results of geochemical reference samples of JG-1 and JB-1 showed general agreement with the other worker's results. Distribution patterns of those elements among the six fractions of highly weathered and relatively unweathered soils were briefly discussed in relation to weathering processes.
