Radiation levels in seawater remain high
Citat:
Tokyo Electric Power Company says it detected 11,000 bequerels of radioactive iodine-131 per cubic centimeter in seawater samples collected around the water intake of the No.2 reactor on Tuesday morning.
That's 280,000 times higher than the maximum allowed under the government's standards.
The recorded radioactive concentration was still high even though it was lower than that of last Saturday, when 7.5 million times the legal limit was detected at the same spot.
Fortfarande höga värden i havsvattnet runt reaktor 2.
Söder om reaktor 4 har värdena sjunkit mycket.
