The purpose of this study is to estimate the contribution of water-derived  137 Cs in the total activity of  137 Cs in brown rice collected from Minamisoma, Fukushima. Three different methods used for the estimation were: 1) the concentration ratio of  137 Cs from water to brown rice (CR –water–rice ), 2) mass balance ratio of the total activity of  137 Cs from water to brown rice (MB –water–rice ), and 3) the ratio of  137 Cs/ 133 Cs. To obtain water-to-brown rice transfer parameters (CR –water–rice  and MB –water–rice ), rice plants were grown in pots filled with soil collected from Minamisoma, Fukushima and irrigated with three types of water (tap water free of  137 Cs containing 0.39 mg L −1  K + , tap water free of  137 Cs containing 1.0 mg L −1  K + , and tap water containing 5.6 Bq L −1 137 Cs and 1.0 mg L −1  K + ). The activity concentrations of  137 Cs in irrigation water, soils, and brown rice collected from Minamisoma, Fukushima were 0.032 Bq L −1 , 1.04, and 0.0012 Bq g −1  dry wt, respectively. Water-derived  137 Cs in brown rice only accounted for 1.9% estimated from the CR –water–rice  parameter. It was 2.8% if estimated with the MB –water–rice  parameter. The ratio of  137 Cs/ 133 Cs in brown rice was 0.00162 Bq ng −1 , similar to that in the exchangeable fraction of soils (0.00173 ± 0.00007 Bq ng −1 , n = 3). Thus, the contribution of  137 Cs from irrigation water to brown rice was negligible. The results estimated by three different methods were in good agreement. Therefore, these methods will be useful tools for assessing the contribution of water-derived  137 Cs in the total activity of  137 Cs in brown rice collected from Minamisoma, Fukushima. The estimation using  137 Cs/ 133 Cs ratio can also be applicable for rice in other regions.
