Wildfire in the mountainous forest of Fukushima, approximately 11 km west-north of the Fukushima Dai-ichi Nuclear Power Plant, burned 75 ha, which was occurred on 29th April and extinguished on 10th May 2017. In this study, we estimate the burning temperature and radiocesium elution characteristics of the residual carbides based on the thermal analysis and the dissolution test for the samples collected at the site of the wildfire to assess the impact of the wildfire on the radiocesium outflow.
