Interview with Dr. Helen Caldicott, MD, Feb. 9, 2014:
At 2:45 in: Units 1, 2 and 3… turned into molten lava, [melted] on to the containment floor made of steel and concrete — and it is not known, but there’s quite a strong possibility that 1, 2 or 3 of them could have melted their way right into the earth.
At 4:00 in: Now there’s molten cores, 3 of them, extremely radioactive, which are bring bathed by the water coming down from the mountains because the containment vessels are broken and the water pours in – and/or 1 or 2 or more of the cores are in the earth being bathed by the water. And that water is incredibly radioactive. Every day since March 11, 2011 300 to 400 tons of radioactive water have been pouring out into the Pacific.
