The plant operator Tokyo Electric Power Co. said early Monday that the concentration of radioactive substances of a pool at the No. 2 reactor was 100,000 times higher than usual for water in a reactor core, correcting its earlier analysis of 10 million times higher.
Chief Cabinet Secretary Yukio Edano told a press conference that the highly radioactive water found at the basement of the No. 2 reactor's turbine building is ''believed to have temporarily had contact with fuel rods (in the reactor's core) that have partially melted.''

It was reported that radiation levels in water in the unit 2 turbine room measured 1 Sv/h, or 10 million times the normal radioactivity of water circulating in an operating reactor, and four times the yearly level allowed for workers

The IAEA announced that workers hospitalized for treatment of radiation burns on Friday had been exposed to between 2 and 6 Sv of radiation at their ankles when standing in water in unit 3.
