To obtain the important information and parameter for the measurement of $$^{137}$$Cs activity per unit area on paved ground, this study evaluated their vertical and horizontal distributions. This study showed that $$^{137}$$Cs was retained in extremely surface layer with mass depth less than 0.5 cm$$^{-2}$$. This study also demonstrated the horizontal variations of $$^{137}$$Cs activity and the relation of the variation with grid size.
