The radiation levels in the building exceed expected levels reaching as high as 700 millisieverts per hour.

A level of radiation at 500 millisieverts per hour may cause cancer, while an acute radiation sickness begins with a dose of 1 sievert and chronic radiation sickness – from 1.5 sievert.

A group of nine specialists from the plant’s operator, TEPCO, entered the No. 1 reactor building at the Fukushima nuclear power plant early in the morning on Monday and spent 30 minutes there, measuring radiation levels.
