Tepco mistakenly published concealed data of activation product in groundwater

(Before It's News)

170,000 Bq/m3 of Mn-54 was measured from groundwater taken in Reactor 1 seaside.

This was represented on Tepco’s analysis data published on 11/26/2014.

Tepco didn’t take a sample from this boring since 11/21/2014, so there shouldn’t be the analysis data of “11/24/2014″. However 170 Bq/L of Mn-54 is represented as “the highest reading in the past analysis”. It reads that the sample was taken on 11/24/2014 and it’s written in red letter for some reason.

Exactly, it is represented as “170.00” and the lower part of letters is missing. It can be 170,000 Bq/L.

All the other readings of near area are lower than detectable level. The previous highest reading was 640 Bq/m3 on 2/20/2014.

Mn-54 has a half-life of only 312 days. It’s activation product of Fe-54 and neutron.
