Gov’t Report: 1,000,000 Bq/m3 of Plutonium was detected in ocean by Fukushima — “Contaminated waters transported rapidly to the east” across Pacific

Gov’t Report: 1,000,000 Bq/m3 of Plutonium was detected in ocean by Fukushima — “Contaminated waters transported rapidly to the east” across Pacific — Fukushima crisis is “the most important direct liquid release of artificial radioactivity into sea ever known” — Scientists: “Remember, its not just cesium isotopes that were released” (ENENews, March 27, 2015):

Comparison between modelling and measurement of marine dispersion, environmental half-time and 137Cs inventories after the Fukushima Daiichi accident, Pascal Bailly du Bois (IRSN), Pierre Garreau (IFREMER), Philippe Laguionie (IRSN), Irène Korsakissok (IRSN), 2014: Contamination of the marine environment following the accident at the Fukushima Daiichi nuclear power plant (FDNPP) represents the most important influx of artificial radioactivity released into the sea ever recorded… The direct liquid releases from FDNPP represent the largest influx of artificial radioactivity into the sea ever occurring over a short period of time on a small spatial scale… Although controlled releases of liquid effluent from the Sellafield reprocessing plant can be compared in terms of total quantities, they have occurred over several years (1970-1980) instead of days, weeks and months as in the case of the FDNPP accident… [W]hatever the detailed current direction at the time of the accident is, water mass fluxes were governed by the generally strong Kuroshio and Oyashio currents that are stable at this scale… Contaminated waters will be transported rapidly to the east… Contamination of the marine environment following the accident at the FDNPP represents the most important direct liquid release of artificial radioactivity into the sea ever known…
