Fukushima Daiichi NPS Prompt Report (Oct 09,2013)Water Leakage near Desalination System (Reverse Osmosis Membrane) at Fukushima Daiichi NPS (Follow-up Information 3)

This is follow-up information regarding the water leakage which occurred today (on October 9) near the desalination system (reverse osmosis membrane: RO-3) inside the temporary warehouse.

Analysis results of the radioactive materials obtained in the leaked water are as follows.
- Cs-134: 3.9 x 102 Bq/L
- Cs-137: 1.3 x 103 Bq/L
- Co-60: 1.1 x 103 Bq/L
- Mn-54: 3.1 x 102 Bq/L
- Sb-125: 9.4 x 103 Bq/L
- All γ: 1.3 x 104 Bq/L
- All β: 3.4 x 107 Bq/L
- All radiation: 3.4 x 107 Bq/L

The leakage amount, etc. is currently under investigation.
