Extremely high level of Cs-134/137 was detected in groundwater taken beside Reactor 2, Tepco announced on 10/24/2014. The specific state of underground is not verified yet. It is groundwater taken from “sub-drain” located beside Reactor 2. (cf, Strontium-90 detected in potentially discharged water from Reactor 1 and 3 [URL]) 460,000,000 Bq/m3 of Cs-134/137 was detected from groundwater on 10/22/2014. 425,000,000 Bq/m3 of Cs-134/137 was also measured the next day. From another sub-drain, 424,000,000 Bq/m3 was detected on 10/22/2014 as well. It was still 321,000,000 Bq/m3 the next day. These sub-drains are located on the mountain side of Reactor 2, which is not affected by frequently reported groundwater contamination in the seaside of Reactor 2. Tepco explains the high readings were caused by the recent typhoon, but the last analyses were implemented in the end of last November and the beginning of last December. The latest readings are approx. 900 times much as the last readings, and it can’t be denied that the contamination level has been gradually increasing even without typhoon. Tepco states the contaminated coolant water that directly touched fuel is not related to the rapidly increased Cs-134/137 density in groundwater.
