[2012]Tepco monitored seawater contamination 10 mins before they “found” the leakage, 850,000 Bq/m3 of Sr-90 detected
Having significantly high level of radiation detected in the seawater, Fukushima Diary researched past sea contamination data.
There have been countless numbers of contamination water leakage. It is not announced the total amount of radioactive material leaked to the environment.
In March 2012, Tepco had the major leakage at the desalination system. Highly contaminated water leaked to the sea nearly for 4 hours. (cf, 1.4×10^11 Bq/m3 of beta nuclides leaked to domestic sewage system [URL])
In this accident, Tepco announced only γ nuclides density to have leaked from the system. (Cs-134/137, Sb-125)
However the report of Nuclear Regulation Authority mentioned Strontium-90 and all β nuclide level in the seawater.
The report was published on 7/5/2013. It is not known when they published the data for the first.
It reads 850,000 Bq/m3 of Sr-90 and 17,000,000 Bq/m3 of all β nuclides were detected from seawater.
For some reason, Tepco collected this sample 10 minutes before they found the leakage.
