(Before It's News)

From Tepco’s report released on 9/4/2015, the density of Strontium-90 increased to 155% of the previous highest reading in the seaside of Reactor 2.

It was measured in groundwater gathered to pump up. The sampling date was 8/3/2015, Sr-90 density was 2,800,000 Bq/m3. The previous highest reading was 1,800,000 Bq/m3, which was analyzed on 7/2/2015.

From the report of 9/15/2015 about the same area, the density of Mn-54, which has 310 days of a half-life, reached the highest reading of 680 Bq/m3 on 9/10/2015. 4 days later, it rose up to 970 Bq/m3 again.

Côté mer du réacteur 2, la radioactivité en Sr 90 dépasse de 155 % le précédent record

Selon un rapport de Tepco publié le 4 septembre 2015, sur le côté mer du réacteur 2 la radioactivité en strontium 90 a atteint 155% du précédent record.

Le relevé a été fait dans les eaux souterraines rassemblées pour être pompées. L’échantillon est du 3 septembre 2015. La radioactivité en Sr 90 est de 2 800 000 (2,8 millions) Bq/m³. Le record précédent, du 2 juillet 2015, était de 1 800 000 (1,8 millions) Bq/m³.

Selon ce rapport du 15 septembre, la radioactivité en Mn 54, dont la période est de 310 jours, a atteint un record à 680 Bq/m³ le 10 septembre 2015 dans la même zone. 4 jours plus tard, il est à 970 Bq/m³.
