UCLA Researchers: Fukushima “not only affecting that local area, but also worldwide”


Asahi Shimbun, Feb 28, 2015 (emphasis added):

The nation’s nuclear watchdog body slammed [TEPCO] over its failure to disclose information on the leakage of radioactive rainwater into the sea… TEPCO President Naomi Hirose… apologized profusely… TEPCO became aware more than a year ago that the concentration of radioactive materials in the water flowing… was high [first disclosing it to regulators] January 2014… TEPCO continued to conceal details, including the fact that the concentration became high whenever it rained… However, TEPCO had decided long ago there was no need to monitor rainwater for radioactive materials.

NHK transcript, Feb 27, 2015 : Experts and local government officials visited the Fukushima Daiichi nuclear plant to examine sources of contaminated water flowing into the seaExperts urged the operator to investigate whether rooftops of other reactor buildings are also sources of tainted water.

Yomiuri Shimbun, Feb 26, 2015: NRA chief slams TEPCO for data reporting delay… after rainwater contaminated with high-level radioactive materials leaked… into the sea… TEPCO reported in January last year that the radioactivity concentration in that trench was higher… TEPCO at last announced… high-level radioactivity [in water] on the rooftop of the No. 2 reactor building… might be one of the sources of contamination… The Economy, Trade and Industry Ministry… pointed out the likelihood of there being other sources of contamination… The Fisheries Agency on Wednesday conducted an emergency hearing with TEPCO officials… and told the utility firm to take measures to minimize damage impacting marine products… “We urge TEPCO to make details clear.”

Japan Times, Feb 26, 2015: [Tepco] admitted Thursday that its latest problem with radioactive water has shattered the trust it was building in Fukushima… and that the decommissioning of the Fukushima No. 1 plant might be delayed [after] the surge in radiation detected in the water draining into the sea… The utility said the source of the contamination is the roof of the No. 2 reactor building, which… remains heavily contaminated.

Naohiro Masuda, head of Tepco’s unit in charge of scrapping Fukushima Daiichi: “The trust of the people in Fukushima is the most important thing… we have damaged that trust… Due to the damaged trust, all of the schedules for the decommissioning tasks could be delayed.”

Arirang, Feb 26, 2015: Tokyo under fire for alleged cover-up of radioactive water — [TEPCO] is under heavy fire for staying silent over a radioactive leak… flowing into the Pacific Ocean.

In the Fukushima Disaster Zone with UCLA researchers, Mar 3, 2015: Four years after Fukushima disaster, some areas remain untouched, clocks recording the exact time that the tsunami swept through. Access is highly restricted but two UCLA researchers were recently given permission to
document the disaster zone. —at 3:45 in — “With this study I think that’s what we’re trying to explore — is that once a nuclear catastrophe strikes, it’s not only affecting that local area, but also worldwide.”

Atmospheric dispersion of Iodine-131 released after the Fukushima event, by Giuseppe A. Marzo, ENEA (Italian National agency for new technologies, Energy and sustainable economic development), 2014: From March 12, 2011, a significant amount of radioactive material… discharged into the atmosphere… Total emission of 131I has been estimated in [128** petabecquerels (PBq)], while 133Xe, and 137Cs total emissions have been estimated in [15,300 PBq and 36.6 PBq], respectively. In this work the global atmospheric dispersion of 131I released by the Fukushima accident is carried out, focusing on this specific radionuclide due to its radiological relevance in terms of consequences on the human health… Figure 1 summarizes the simulation results. It illustrates the radioactivity concentration due to 131I released into the atmosphere at specific times and integrated over the total atmospheric column. Immediately after the initial release on March 12, the plume moved eastward reaching the United States west coast on [March 15 at 10:00p PST]… In early April the plume extended over the entire northern hemisphere… A significant accidental event occurred at the Fukushima NPPs… volatile radionuclides such as 131I were transported away from the source posing significant concern on the safety of the population and the environment worldwide… the atmospheric dispersion of 131I [was] covering the entire northern hemisphere by early April

**According to a document released by TEPCO, “Our result shows a higher I-131 amount (500PBq) compared to the result obtained from a thirdparty organization (120-200PBq).”
