Short summary
The detailed atmospheric releases during the Fukushima Daiichi Nuclear Power Station accident were estimated using a reverse estimation method with atmospheric and oceanic dispersion models. The major releases occurred on the afternoon of 12 March, midnight of 14 March, the morning and night of 15 March, and the morning of 16 March in 2011. Several atmospheric dispersion models with our new source term reproduced the local and regional patterns of I-131 and Cs-137 deposition and air dose rate.
