On 7/10/2013, Tepco admitted contaminated water is leaking from the turbine buildings of reactor2 and 3 to the trench, which is outside of the building. Tepco took the sample from the shaft of the trench connected to reactor3 and analyzed it on 7/11/2013. They measured 100,000,000,000 Bq/m3 of Cs-137 and 50,000,000,000 of Cs-134. In total, Cs-134/137 density was 150,000,000,000 Bq/m3 at 1m depth in the shaft. The salt density was 11,000 ppm. The highest atmospheric dose was 0.1 Sv/h above … Continue reading Tepco admitted leakage from reactor2&3 to the trench,”150,000,000,000Bq/m3 of Cs-134/137, 0.1 Sv/h”
