Keywords:Fukushima Daiichi Nuclear Power Plant Accident, Air Dose Rate Prediction, Decontaminated Areas, Prediction Model, Two-Component Model

Since the model’s parameters of the two-component model were constructed on the basis of measurement data not adequately reflected decontamination, we compared the predictions from the model for the air dose rate to measurements of the air dose rate obtained in follow-up surveys post-decontamination carried out by the Ministry of the Environment.
