In this study, we sampled a core soil using a core sampler (0-30 cm) at Kawasaki. A sequential extraction procedure was used to characterize radiocesium in each layer of soil. We selected six sampling points in cosideration of the vegetation. Four soils were collected at 900 cm $^{2}$ range area. Core sample (0-30 cm) was devided into 5 cm layer and put in U-8 container, respectively. From measurement results, the vertival distribuition of radiocesium in core soil was 2.5 Bq kg $^{-1}$ (0-5 cm), 22.3 Bq kg $^{-1}$ (5-10 cm), 3.4 Bq kg $^{-1}$ (10-15 cm), 0.3 Bq kg $^{-1}$ (15-20 cm), 0.8 Bq kg $^{-1}$ (20-25 cm), 1.0 Bq kg $^{-1}$ (25-30 cm). It is indicated that radiocesium penetrate to deeper layer at Kawasaki.
