- Tepco mis-analyzed 167 samples since 311/ Correct readings can be over 10 times much as wrong ones (Fukushima Diary, Feb 16, 2014):
Following up this article.. [Wrong analysis for 2.5 years] Tepco “All the radiation analysts were outsourced staff. No Tepco employee in Lab.” [URL]
The wrongly analyzed samples are up to 167, Tepco announced in their press conference of 2/14/2014.
They were stating all the nuclides might have been underestimated including Strontium-90, but they re-stated actually it was only all β nuclide to have been underestimated.
Among 20,866 samples to detect all β nuclide from 311 to October of 2013, 0.8% of the samples were analyzed in the wrong manner.
However, they commented the correct reading may be over 10 times much as originally announced data.
For example, last July they measured 5,000,000,000 Bq/m3 of Strontium-90 from the groundwater taken in the seaside of reactor2. (cf, 5,000,000,000 Bq/m3 of Strontium-90 measured from groundwater last July / Tepco not announced for half a year [URL 2]
From this sample, they also measured 900,000,000 Bq/m3 of all β nuclide. The correct reading can be over 9,000,000,000 Bq/m3 with 166 other samples.
