(2) 14 March: Dry deposition on 14 March at Kakioka, 150 km south of the FNPP-1. (3) 16-20 March: Strong re-suspension by wind. (4) 12-20 March: Highest risk of internal dose, particularly for children. (5) 20-21 March: Wet deposition at Kakioka by the first substantial rain. The rain ceased re-suspension.
