550,000 Bq/m3 of Cs-134/137 measured outside of the impervious wall / Contaminated water overflowing the wall

According to Tepco, high level of Cesium-134/137 was detected outside of the impervious wall, where is only 2m from the sea. Tepco built the underground wall on the coastal line

[Mystery] Cs-134/137 concentration is higher in the leaked water than the leaking tank

About 300m3 of contaminated water leakage, Tepco published the Cs-134/137 concentration data of the tank on 8/26/2013. From their report, 44,000,000 Bq/m3 of Cs-134 and 92,000,000 Bq/m3 of Cs-137 were

Cs-134/137 level of groundwater jumped up in the seaside of reactor2

According to Tepco, Cesium-134/137 density in groundwater is increasing near one of the groundwater pumps in the seaside of reactor2. In order to reduce the groundwater, Tepco installed pumps. The

Plant hazard

Cesium-134/137 level jumped up 10~1,000 times much as average on the top of reactor3

According to Tepco, Cs-134/137 levels jumped up in the air on the W-S-W side of the top of reactor3 building. Cs-134 reading was 1,200 Bq/m3, Cs-137 reading was 2,600 Bq/m3.

[Marine contamination] Cs-134 measured from Miyagi offshore seawater, radiation level not been decreasing

According to Tepco, Cs-134 was measured from seawater offshore Miyagi prefecture. The half-life of Cs-134 is 2 years. Measurement of Cs-134 proves the radioactive contamination reached offshore Miyagi. The highest
