Abstract: Analyses of 114 soil samples in Ningbo City show that, in general, there are statistical differences of 137Cs and 40K contents between every layers; the other kinds of natural radionuclides present an increasing tendency with depth. When the γ radiation dose rate is estimated by Beck Formula, owing to the effect of those nonuniform distributions is less than 1% and can be ignored.

Key words: Natural radioactive nuclides, 137Cs, Nonuniform distribution, Depth o soil, China
