摘要：

The reasons why rice Cs-137 concentrations increase near the water inlet were investigated using rectangular experimental plots settled in paddy fields. The Cs-137 concentrations in brown rice and rice straw were highest at 1 m from the inlet and decreased gradually with increasing distance, showing a negative correlation with soil exchangeable potassium content (Ex-K). The Cs-137 concentration in brown rice was negatively and positively correlated with yield and sterility rate, respectively. These results suggest that soil Ex-K reduction and rice anomalies occurred near the water inlet and could contribute to the local elevation of Cs-137 concentrations in rice.
