Models for Assessment on the Uptake of Radio-cesium by Rice Using Soil Parameters Calibrated for Paddy Fields in Fukushima Prefecture

Two recently developed models of radio-cesium (RCs) transfer from soil to rice grains that were parameterized and ready-to-use for paddy fields in Fukushima reviewed establish model-based countermeasures food safety management Fukushima. A probability density function model the factor based on exchangeable potassium (K) was compared with a grain RCs concentration basis K. The relevance between these two demonstrated using as quantitative index availability observed data. results indicate is affected by use log-normal distribution justified pattern RCs. This finding improves accountability differences modeled densities different regions helps design purposes, such precautions K fertilization or conservative risk assessment shipping restrictions.
