Tokyo - (PanOrient News) The operator of the crippled Fukushima Daiichi nuclear power plant, Tokyo Electric Power Co., or TEPCO, concealed data showing surges in radiation levels at the Fukushima No. 1 nuclear power plant in March, one day before a hydrogen explosion injured seven workers, the daily Asahi Shimbun reported.
The paper cited a 100-page internal TEPCO report containing minute-to-minute data on radiation levels at the plant as well as pressure and water levels inside the No. 3 reactor from March 11 to April 30.
This is certain to make another blow to the company image that is shattered by its handling of the worst nuclear accident in Japan's history.
The unpublished information shows that at 1:17 p.m. on 13 March, 300 millisieverts of radiation per hour was detected inside a double-entry door at the No. 3 reactor building. At 2:31 p.m., the radiation level was measured at 300 millisieverts or higher per hour to the north of the door. Both levels were well above the upper limit of 250 millisieverts for an entire year under the plant's safety standards for workers.
“But the workers who were trying to bring the situation under control at the plant were not informed of the levels.”
