Breaking news Contaminated water crisis Fukushima Plant

Highest density of Tritium measured from seawater of all of the crippled reactors even outside of underground wall

    On 6/27/2014, Tepco announced they measured the highest density of Tritium from Fukushima plant port. The sample seawater was taken in water intake of Reactor1, 2, and 3&4,

Contaminated water crisis Environmental contamination Sea contamination

The highest level of Tritium measured in seawater of Fukushima nuclear plant port

According to Tepco, they measured the highest level of Tritium from seawater on 8/11/2013. The location is the north of reactor1~4 water intake. The reading was 3,800,000 Bq/m3. This is

Contaminated water crisis Cover-ups

[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


Sr-89/90 data of reactor1~4 water intake has been “under analysis” since 2012

On 6/19/2013, Tepco released the nuclides analysis result of radioactive materials in the reactor1 ~ 4 water intake. However, they haven’t published the readings of Strontium-89 and Strontium-90. The oldest

Sea contamination

Sr-90 detected 6 times much as safety limit from seawater of water intake

According to Tepco, 170,000 Bq/m3 of Sr-90 was measured from seawater. Density Limit Specified by the Reactor Regulation is 30,000 Bq/m3. The measurement reading is 5.7 times much as the


Radioactivity density in seawater of reactor3 reached the highest reading since 2/1/2013, 5 times much as reactor2

According to Tepco, the radioactivity density in seawater of reactor3 is in the increasing trend. On 5/16/2013, they measured 200,000 Bq/m3 of Cs-134 and 380,000 Bq/m3 of Cs-137, which is


Cesium134/137 has been measured from the seawater in front of reactor6 water intake

According to Tepco’s report “Radioactivity Density of the Seawater in the Port of Fukushima plant” published on 12/5/2012, Cs-134/137 has also been measured from the seawater in front of reactor6

Contaminated water crisis Sea contamination

[Radiation leakage to the sea] Radiation level at water intake of reactor1~4 is slowly increasing

According to Tepco’s report of “Radioactivity Density of the Seawater at the South of Unit 1-4 Water Intake of Fukushima Daiichi NPS (Bq/ L)”  published on 11/26/2012, the radiation level
