Based on an analysis of the shape of the ¹³⁷Cs vertical profiles and a comparison with ideal ¹³⁷Cs vertical profiles, the authors collected more than 200 ¹³⁷Cs vertical profiles, which included 121 stations in China’s coastal areas, and more than 100 stations in other areas of the world. The results show that there exist six main types, i.e.: 1) discontinuous 137Cs curves: 2) continuous ¹³⁷Cs curve without characteristic peak; 3) characteristic peak on the lower part of the continuous ¹³⁷Cs curve; 4) characteristic peak on the upper part of the continuous ¹³⁷Cs curve; 5) increasing activity of ¹³⁷Cs with depth; and 6) decreasing activity of ¹³⁷Cs with depth.
