460,000,000 Bq/m3 of Cs-134/137 detected from mountain side of Reactor 2
25 October, 2014
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.
Tepco accidentally destroyed a part of Reactor 1 cover at dismantling preparation

Following up this article.. Tepco started dismantling Reactor 1 cover – Video [URL]
Tepco mis-operated the crane to spray scattering inhibitor and opened an excessively large hole on the cover of Reactor 1, Tepco announced on 10/28/2014.
The size of the hole was 2m × 1m, whereas it was supposed to be 0.3m × 0.3m. Tepco states it was due to a sudden gust of wind around 8:20 of 10/28/2014.
The cover is to prevent the radioactive material from spreading to the atmosphere. Tepco comments the surrounding radioactive density didn’t show increase however.
The spray device of scattering inhibitor has the spear-shaped top to open a hole on fibrous panel of the cover. It is not planned when to restart the dismantling procedure.

Nuclear expert Arnie Gundersen of Fairewinds Energy Education on Radio Ecoshock, Oct 27, 2014 (11:30 in): We work with a woman… an organic gardener. Every year, she’s taken the seeds from her garden, planted, then harvested seeds from those plants to be the next year’s crop. So she’s got 4 years now of seeds that have been growing about 30 miles (~50 km) from Fukushima. She’s beginning to experience gargantuanism in her food now, which is an indication of radiation damage. It’s one of the many DNA changes that occur after a couple of generations. So we know that gardeners and plants that are outside the exclusion zone are seeing the effects of chronic levels of radiation that the Japanese would choose to ignore.
