300 tons of radioactive water according to reports.

From The Japan Times article by Reiji Yoshida:

About 300 tons of highly radioactive water had leaked from a tank at the damaged Fukushima No. 1 nuclear power plant as of Tuesday afternoon, Tokyo Electric Power Co. said. 

Tepco claims none of the water, which had been used to cool its stricken reactors and is highly radioactive, has flowed directly into the Pacific, apparently contained by a 30-cm-high waterproof concrete barrier surrounding dozens of tanks, including the leaking No. 5 tank. But some of the water may have been absorbed into the ground, joining with already tainted groundwater. 

Where the leak is occurring in the tank, which is bolted together and has sealed seams, remains elusive, however, even after workers finished pumping water from inside the barrier Tuesday afternoon.

The Nuclear Regulation Authority released a preliminary assessment of a level 1 incident on the eight-notch international severity scale for nuclear accidents. 

The amount of beta rays being emitted by radioactive materials in the leaked water, including strontium, was 80 million becquerels per liter, Tepco said. 

Not the best news coming out of Japan.
