From NHK News, more bad news :
" At the quake-hit Fukushima nuclear power plant, high radioactive density detected in 3 turbine buildings may further delay work to restore the cooling systems for the overheated fuel rods.
Tokyo Electric Power Company says that on Sunday it detected 100,000 times the normal density of radioactive substances in the leaked water in the Number 2 reactor's turbine building at the Fukushima Daiichi nuclear power plant. The water surface had a high radiation level of more than 1,000 millisieverts per hour.
In similar tests conducted earlier, about 10,000 times the normal radioactive density had been detected in the turbine buildings of the Number-1 and -3 reactors as well."
