From Fukushima Diary
5 Billion Bq of Strontium-90 flows to the Pacific on the daily basis in 2014. Tepco announced in the press conference of 8/25/2014.
This is due to the contaminated water overflowing from the seaside of Reactor 1 ~ 4 to Fukushima plant port.
They also announced 2 Billion Bq of Cesium-137 and 1 Billion Bq of Tritium flow to the sea every single day as well.
Fukushima plant port is not separated from the Pacific. Discharged nuclide naturally spreads to the sea.
