Estimation of the cesium is important because it enters the human food cycle during nuclear accidents. To prevent endangerment of human health, the level of radiation contamination in edible plants in the affected areas should be determined. In this research, using two- and three-compartmental models, transfer coefficients of 137Cs have been obtained in the plant components. To calculate the transfer coefficients, two- and three-part models have been used for plants such as mushrooms, cabbage and spinach. The input of model was the cesium information in the soil of Fukushima for 8 months after the accident. The results obtained from modeling of the different edible plants with two- and three-part models and information of the Fukushima data for these plants show that the values of transfer coefficients for the body of mushrooms, spinach leaves and broccoli were 0.018, 0.0808 and 0.0908, respectively, which corresponds to the practical values measured in the Atomic Energy Agency Technical Report No. 472. The calculated transfer coefficients correspond to the values recommended in the technical report of the Atomic Energy Agency and the obtained results can be used to predict radioactive contamination in the nuclear accidents.
