Fukushima I Nuke Plant: Amount of Strontium in Leaked Water, per TEPCO

From TEPCO's December 6 press release page:

150 liters of this radioactive strontium-rich water leaked into the ocean from the evaporative condensation apparatus (part of the contaminated water treatment system), via the regular drains.

Density:
Strontium-89: 74,000 becquerels/cubic centimeter
Strontium-90: 100,000 becquerels/cubic centimeter

Total amount of radioactive materials (including cesium) that leaked into the ocean this time: 26,000,000,000 becquerels, or 26 billion becquerels.

TEPCO says it is 12% of "annual discharge target control of radioactive liquid waste" at Fukushima I Nuclear Power Plant. That's one way of putting it. Another way is that it is only a fraction of what has already been discharged, to the tune of between 4,700 terabecquerels (TEPCO estimate so far, though the company was to recalculate by the end of November; did it?) and 27,100 terabecquerels (France's IRSN estimate), and these numbers do not include strontium.
