This is follow-up information on the "water leak at a tank in the H4 area in Fukushima Daiichi Nuclear Power Station" found on August 19.
We performed the analyses of water sampled yesterday (on September 11) in observation holes (E-1: in north of the tank No.5 in Group I in the H4 area (outside of a dike) where water leakage was found; E-2 in south of the tank No.5 in Group I in the H4 area (outside of a dike) where water leakage was found) around H4 tank area.
The result of E-1 was higher than the result obtained on September 10 (64000Bq/L).
Based on the probability of influence on these results by leakage in H4 area tanks, we continue to analyze the observation holes nearby and investigate the area of leakage.
<Observation hole: E-1>
- Sampled on September 11
Tritium: 97000Bq/L
All β: 1500 Bq/L
<Observation hole: E-2>
- Sampled on September 11
Tritium: 300Bq/L
All β: Below the detection limit value (detection limit value: 20Bq/L)
