Fukushima: Bullshit and disinformation from MSM

I posted a comment on Mike Ruppert's FB page saying that there still be fools who deny the reality – and – hey presto – as if on command, here is an example.



Researcher: Californians don't need to worry about Fukushima radiation



21 August, 2013

Japan's nuclear watchdog is considering raising the danger level at the Fukushima plant to "serious." That's after 300 tons of contaminated water leaked from a holding tank there — some of it possibly reaching the Pacific.

Kei Iwamoto, a radiation researcher with UCLA, says the pollution may pose a threat to the immediate area — but beachgoers in California shouldn't worry.
"The ocean is so large and we are so far away. You know that 300 tons is equivalent to a drop in 50,000 Olympic-sized pools. So it's a huge dilution. And what we're going to see over here is going to be undetectable."
Officials with the nuclear plant are still hunting the source of the leaks.



The first of the comments says more sense than the article:


This is incorrect. While many people assume that the ocean will dilute the Fukushima radiation, a previously-secret 1955 U.S. government report concluded that the ocean may not adequately dilute radiation from nuclear accidents, and there could be “pockets” and “streams” of highly-concentrated radiation.

Last year, scientists from the National Oceanic and Atmospheric Administration’s (NOAA) Pacific Marine Environmental Laboratory and 3 scientists from the GEOMAR Research Center for Marine Geosciences showed that radiation on the West Coast of North America could end up being 10 times higher than in Japan:

"After 10 years the concentrations become nearly homogeneous over the whole Pacific, with higher values in the east, extending along the North American coast with a maximum (~1 × 10−4) off Baja California.

"With caution given to the various idealizations (unknown actual oceanic state during release, unknown release area, no biological effects included, see section 3.4), the following conclusions may be drawn. (i) Dilution due to swift horizontal and vertical dispersion in the vicinity of the energetic Kuroshio regime leads to a rapid decrease of radioactivity levels during the first 2 years, with a decline of near-surface peak concentrations to values around 10 Bq m−3 (based on a total input of 10 PBq). The strong lateral dispersion, related to the vigorous eddy fields in the mid-latitude western Pacific, appears significantly under-estimated in the non-eddying (0.5°) model version. (ii) The subsequent pace of dilution is strongly reduced, owing to the eastward advection of the main tracer cloud towards the much less energetic areas of the central and eastern North Pacific. (iii) The magnitude of additional peak radioactivity should drop to values comparable to the pre-Fukushima levels after 6–9 years (i.e. total peak concentrations would then have declined below twice pre-Fukushima levels). (iv) By then the tracer cloud will span almost the entire North Pacific, with peak concentrations off the North American coast an order-of-magnitude higher than in the western Pacific."

"This finding is seconded by a team of top Chinese scientists who have just published a study in the Science China Earth Sciences journal showing that Fukushima nuclear pollution is becoming more concentrated as it approaches the West Coast of the United States, that the plume crosses the ocean in a nearly straight line toward North America, and that it appears to stay together with little dispersion..."
