Old News Worth Re-Visiting


I'm working on a presentation on Fukushima's nuclear refugees and the violation of human rights to health in Japan and I was reviewing old materials I collected.

I found this excerpt from 2011 that is worth re-visiting:

Hiroko Tabuchi and Andrew Pollack Japan Is Struck by Powerful Aftershock
 New York Times (April 7, 2011)
  ... Flashes of extremely intense radioactivity have become a serious problem, [a western nuclear executive who spoke on the condition of anonymity to protect business connections in Japan] said. Tokyo Electric’s difficulties in providing accurate information on radiation are not a result of software problems, as some Japanese officials have suggested, but stem from damage to measurement instruments caused by radiation, the executive said. 
Broken pieces of fuel rods have been found outside of Reactor No. 2, and are now being covered with bulldozers, he said. The pieces may be from rods in the spent-fuel pools that were flung out by hydrogen explosions....

Majia here: What exactly was meant by "flashes of extremely intense radioactivity"?

Notice also confirmation that fuel rods were found outside reactor no 2 and were bulldozed.  It is not clear which pool they were projected from but I'm guessing it was reactor unit 3's pool.

Reuters had reported just a few days previously that plutonium from unit 3's spent fuel pool was found in the soil at the site.
Reuters 3/28 Plutonium found, problems mount at Japan nuke plant http://www.reuters.com/article/2011/03/28/us-japan-quake-idUSTRE72A0SS20110328  
"Plutonium found in soil at the crippled Fukushima nuclear complex heightened alarm on Tuesday over Japan's lengthy battle to contain the world's worst atomic crisis in 25 years—believed to come from #3’s spent fuel rods.
Majia here: These two articles offer support for the hypothesis that plutonium from Fukushima unit 3 was blown into the Pacific ocean in the initial explosion and/or leached into the ocean subsequently in the form of contaminated ground water.

TEPCO never reported any data for plutonium contamination that I saw, but the company did report that up to 20 trillion becquerels of cesium-137, 10 trillion becquerels of strontium-90 and 40 trillion becquerels of tritium entered the ocean via groundwater, Between May 2011 and August 2013 http://www.bloomberg.com/news/2014-02-20/tepco-says-new-leak-of-radioactive-water-found-at-fukushima-site.html

However, I'm not sure anyone should believe TEPCO's figures given the company's proven tendency to withhold and manipulate data. For example, 
TEPCO withheld Fukushima radioactive water measurements for 6 months because of rising strontium levels (2014, January 9) The Asahi Shimbun http://ajw.asahi.com/article/0311disaster/fukushima/AJ201401090060

Tokyo Electric Power Co. has withheld 140 measurements of radioactive strontium levels taken in groundwater and the port of the Fukushima No. 1 nuclear plant between June and November last year. TEPCO has been releasing the combined levels of all radioactive substances, including strontium, that emit beta rays, at the crippled nuclear plant. But strontium levels exceeded the all-beta readings in some instances, leading the utility to decide they were “wrong” and to withhold them from public releases, TEPCO officials said Jan. 8. Previously, TEPCO officials said they had not released the data because the numbers were not confirmed.
NHK has suggested that there is an additional source of contamination outside of the port area as well, perhaps stemming from the subterranean journey of ground water running under Daiichi site and emptying ultimately into the Pacific Ocean, after encountering highly radioactive waste bulldozed under debris and/or into the ocean, in addition to the uncontained and melted nuclear fuel under the site.

For background see NHK documentary also suggests an additional source of water contamination: Fukushima Daiichi's Hidden Crisis: http://vimeo.com/8559542

I have not seen any research on plutonium bioaccumulation in ocean life.

Yet plutonium has been proven to bioaccumulate in aquatic life, and Americium even more so.

I would like to see full spectrum analysis of whale and sea lion organs, with researchers providing readings for all radioactive isotopes of carbon, iodine, cesium, silver, strontium, uranium, plutonium, americium, etc, etc. etc.
Those readings should read in tandem with data on bioaccumulation of lead, arsenic, and mercury in those same organs.

Let us have a full spectrum analysis and we will see truly how contaminated ocean life has become.
