Abstract
This paper presents a readily understandable hydrologic-based method to calculate the effective dose emerges from the intake of radioactivity on agricultural products derived from radioactive fallout on the soils. We discuss the intake of polished rice as an example of agricultural product. The authors have been studied internal dose calculation regarding to the human body. The scope of our research is expanded from the human body to the soils in this report. Our modeling of the radiocesium transfer from the soils to the human body is based on the previous research regarding the vertical infiltration, the transfer factor to plants, and the residence time of cesium in the soils. We calculate analytically in concise formalization the intensity of radioactivity on the soils per area and the effective dose derived from the intake of radioactivity on the rice using measured radioactive fallout after the Fukushima Daiichi NPP accident.
