Contaminated water crisis

[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

Contaminated water crisis

Radiation level in leakage detector hole water of reservoir No.3 jumped up 5 times much

About the major leakage of highly contaminated water, Tepco has admitted 3 of 7 reservoirs are leaking. According to Tepco, the total β nuclide in leakage detector hole water jumped

Contaminated water crisis

[Radiation penetrating underground] β nuclide detected in 13 of 22 observation holes around the leaking reservoirs

According to Tepco, β nuclides were detected from ground water around the leaking reservoirs. Detection of β nuclides strongly suggests the possibility that the leaking contaminated water is already penetrating

Contaminated water crisis

1,400,000 Bq/m3 of β nuclide detected from reactor1 sub-drain water

According to Tepco, high level of β nuclide is measured from the water of sub-drains. The sub-drain water is assumed to flow into the basement floors of the reactors. The
