[Twice a month → Once a month] Tepco to decrease the frequency of Sr-90 analysis in seawater

High level of radiation is detected in groundwater and seawater. It is suspected that contaminated groundwater is flowing to the sea. On 7/12/2013, Tepco announced they are going to take

Contaminated water crisis

Former Fukushima worker “Stopping groundwater flowing to the sea may cause various problems”

High level of radiation is measured from groundwater and seawater. Tepco suspects there is a “possibility” that the contaminated groundwater is flowing to the sea, they are building the underground

Contaminated water crisis

92,000,000 Bq/m3 of all β nuclides detected from the new boring at 38 m from the sea

According to Tepco, high level of all β nuclides (such as Strontium-90) were detected from the new boring. The reading was 92,000,000 Bq/m3. Tepco hasn’t tested a sample from this

Contaminated water crisis

Tepco “Tritium density has been rising in seawater since May.”

According to Tepco, Tritium density in seawater has been increasing since this May. (The graph below.) In their report about radioactive material density in groundwater and seawater published on 7/12/2013,

Contaminated water crisis

1,200,000 Bq/m3 of Sr-90 detected from groundwater east side of reactor2, “The data is 5 weeks old”

On 7/11/2013, Tepco finally published a part of the data of Strontium-90 density in groundwater. In the groundwater taken from boring No.1, 1,200,000 Bq/m3 of Strontium-90 was detected. The boring

Contaminated water crisis

1,400,000 Bq/m3 of all β detected from the boring east of reactor3, “Groundwater contamination spreading to south”

High level of all β nuclides, Tritium and Cs-134/137 are measured from groundwater and seawater of Fukushima nuclear plant. According to Tepco, 1,400,000 Bq/m3 of all β nuclides were also

[Groundwater] Tepco “Cs-134/137 density decreased after filtration”

Following up this article..[Groundwater] Cs-134/137 density jumped 1.2 times much as one day before, “33,000,000 Bq/m3, highest ever again” [URL] On 7/10/2013, Tepco showed Cs-134/137 density can be decreased by

Contaminated water crisis

[Groundwater] Cs-134/137 level spiked 90 times much as 3 days before, “27,000,000 Bq/m3 of Cs-134/137, highest ever”

On 7/6/2013, Fukushima Diary reported “309,000 Bq/m3 of Cs-134/137 detected from the groundwater, “Cs-134/137 may travel underground too” [URL]” On 7/8/2013, Tepco measured 27,000,000 Bq/m3 of Cs-134/137 from the groundwater

[Column] Summary of Fukushima situation ~What we are not informed of

I don’t know if I’m doing the good thing for my country. I believe our descendants would evaluate me accordingly. It’s not my job anyway. The harder you push, the

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
