Cs-134/137 and all β nuclides (including Sr-90) density showed the rapid increase in groundwater, according to Tepco. The sample was taken in the seaside of Reactor 2. Sampling date was 1/12/2015. Compared to the previous measurement of 1/8/2015, Cs-134/137 density rose up by 57 times, all β nuclides density also rose up by 57 times. This is the highest reading measured from this boring. Tepco hasn’t identified the reason. This boring is located outside of the underground wall to stop … Continue reading Radioactive contamination level jumped over 57 times outside of underground wall
