Contaminated water crisis Sea contamination

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

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.
