180,000 Bq/m3 of tritium from groundwater of Fukushima plant area

Following up this article..Tepco plans to pump up groundwater and discharge it to the sea

From the priority measurement of radiation, tritium was detected from groundwater at one of the sampling locations.

The first measurement was conducted on 2/21~22/2012, the second one was conducted on 5/24/2012.

14.7 ~ 13.9 O.P.m and 25.7 ~ 18.1 O.P.m indicate the height from the near sea level of where the sample was taken.

 

 

Also, it’s in the increasing trend from 2/21~22/2012. The highest reading was 180,000 Bq/m3.

 

Tepco states it’s still low level for the concentration of notice, which is 60,000,000 Bq/m3 but it’s not announced what this figure is based on.

The location to take the sample is higher than nuclear buildings, Tepco assumes Tritium leaked as evaporated water from the reactors, fell on the ground and sank into underground.
