TEPCO Admits: 80 BILLION Bq/m3 Was Actually 280 BILLION Bq/m3 In Last Year’s Leak

[Tepco’s upward revision] “80 BILLION was actually 280 BILLION Bq/m3 in last summer’s leakage” (Fukushima Diary, April 12, 2014):

Following up this article.. Leaked all β of “300m3 leakage accident” was also underestimated / INES level might be increased [URL]

All β nuclide density was 280,000,000,000 Bq/m3 in the leaked tank water last summer. All β nuclide means the collective of the nuclides to include Strontium-90.

Tepco announced the all β nuclide density was 80,000,000,000 Bq/m3 in the beginning. They raised the reading by 3.5 times much after over half a year has passed.

Though contaminated water issue is the main concern of the entire Pacific region, Tepco was mis-analyzing the contaminated water and the wrongly analyzed samples were all underestimated instead of overestimated. Tepco states the wrongly analyzed samples were only 173, and they submitted the report about the 168 revised analysis data to NRA (Nuclear Regulation Authority) on 4/11/2014.

The analysis of “280,000,000,000 Bq/m3″ was quietly mentioned in this report, which Tepco didn’t refer to until a press inquired in the press conference of 4/11/2014.

Whether it was intentional or not, the government of Japan and Tepco tend to publish the unrealistically optimistic data in the beginning, and have upward revision when the public opinion withdraws from the issue.
