Modelling the global atmospheric transport and deposition of radionuclides from the Fukushima Dai-ichi nuclear accident (pdf), 2013 (emphasis added): Chino et al. (2011) estimate a total [131I] release of 150 PBq [...] results are considered by [the] authors to be lower estimates and to have an error of at least a factor of five. Winiarek et al. (2012) estimate the lower bound of the total activity of 131I released into the atmosphere [...] between 190 and 700 PBq
[...] We estimate that the land area affected by the deposition of
radioactivity in excess of 40 kBqm² is approximately 34,000 km². [...]
this part of Japan is inhabited by 9.4 million people. The surface area
that received a total deposition greater than 10 kBqm² encompasses
parts of the Tokyo metropolitan area, and approximately covers 60,000
km2, being inhabited by 46 million people. We emphasize that this is based on the emission of 150 PBq 131I estimated by Chino et al. (2011), which might actually be a factor of five too low.
