The tool generates hourly-averaged air concentration data at the simulation grids nearest to the whereabouts from datasets of the WSPEEDI-II. This paper describes the overview of the developed tool and demonstrates tentative comparisons between direct measurement-based and calculated internal doses to 411 persons with the data available, 13th International Conference on Radiation Shielding (ICRS-13) & 19th Topical Meeting of the Radiation Protection & Shielding Division of the American Nuclear Society -2016 (RPSD-2016)}, title = {Development of a tool for calculating early internal doses in the Fukushima Dai-ichi nuclear power plant accident based on atmospheric dispersion simulation}, year = {2016} }
