The background values of elements in soil have been investigated by INAA. The contents of 8 REE (La, Ce, Nd, Sm, Eu, Tb, Yb and Lu), U and Th in 364 top soil samples (A horizon) in China were determined by INAA. The samples were collected from some typical areas in China and covered main soil types of these areas. The background values of above elements in soil of the different areas and the whole soil studied in China are reported in present paper. The distribution characteristics of REE, U and Th in soils are also discussed.
