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 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 (0-5 cm), 22.3 Bq kg (5-10 cm), 3.4 Bq kg (10-15 cm), 0.3 Bq kg (15-20 cm), 0.8 Bq kg (20-25 cm), 1.0 Bq kg (25-30 cm). It is indicated that radiocesium penetrate to deeper layer at Kawasaki.
