NHK, Feb. 19, 2014: Highly radioactive water leaks at Fukushima plant […] [Tepco] says water containing extremely high levels of radioactive substances has leaked from a storage tank. [and] was found on Wednesday night […] the water leaked from a seam near the top of the tank. It traveled along a rainwater pipe and flowed outside the barrier that surrounds the tank. […] Officials say their investigation is still underway.

Bloomberg, Feb. 19, 2014: Tepco Says New Leak of Radioactive Water Found at Fukushima Site […] About 100 metric tons (26,400 gallons) of water […] Beta radiation readings of 230 million becquerels per liter were taken in a water sample collected today near the H6 tank area […] About 300 tons of contaminated groundwater seep into the ocean each day […]

“The sample was collected today near the H6 tank area”… Why not sample the water from inside the tank it leaked out of?
100 metric tons with 230,000,000 Bq/L = 23 Trillion Bq of Strontium-90 & other beta emitters, with half generally being Strontium-90 — about 11.5 trillion Bq of Sr-90
Tepco claims 10 trillion Bq of Sr-90 entered the sea from May 2011 to Aug. 2013
Kyodo News, Feb. 20, 2014: Roughly 100 tons of highly radioactive water leaked [Tepco] said Thursday [with] 230 million becquerels per liter of strontium and other beta ray-emitting radioactive substances. The utility believes the liquid has not flowed into the adjacent sea as there is no drainage nearby […]

Tepco “believes the liquid has not flowed into the adjacent sea”… yet. A recent special on Japan TV about Fukushima’s contaminated water summed up the situation this way:

NHK (at 36:30 in): “What has become clear is that it’s very hard to control radioactive materials once they get into the environment.”
