Gov’t Expert: Fallout in California thousands of times higher than we expected for several days after Fukushima explosions — ‘Orders of magnitude’ above estimates at start of crisis, even though estimations based on Chernobyl — Article: Releases at these levels would mean “many hundreds of kilograms” of “many other fission products!” (MAP)

World Meteorological Organization (WMO)– Commission of Aeronautical Meteorology, July 15-17 2014 (emphasis added): Fukushima fully showed reliable source terms for assessing accident severity and consequences in real-time were not readily available in the early phase… The inherent uncertainty involved poses questions in the accuracy of the modelled results which could differ from the observation by orders of magnitude.

Central Institute for Meteorology and Geodynamics (ZAMG), by WMO team member Gerhard Wotawa, et al, 14th Conference on Harmonisation within Atmospheric Dispersion Modelling: Only minutes after the [Unit 1 explosion] was disclosed, the first model simulation of the emergency response system was initiated…source term was estimated based on experiences from Chernobyl… a continuous release rate of [100 quadrillion Bq/day of Iodine-131], [10 quadrillion Bq/day of Cesium-137] and [10 quintillion Bq/day of Xenon-133]… CTBTO [data was used, which has] a very high accuracy… The plume left Japan and… reached the western coast of North America on March 18… [The] ZAMG… estimate amounted to about [400 quadrillion Bq of I-131] and [40 quadrillion Bq of Cs-137]… Indication is found that significant amounts of 131I, 137Cs and 133Xe were already set free during the first days of the accident, exceeding initial estimates by orders of magnitude.
