Six more employees of Tokyo Electric Power Co. working at the Fukushima No. 1 nuclear power plant were exposed to more radiation than allowed, the Japanese newspaper Asahi Shimbun reported on Thursday.
The government raised the upper limit for workers dealing with the Fukushima accident to 250 millisieverts. However, TEPCO announced June 13 that six additional employees had been exposed to more than that level of radiation. The company had previously announced that two employees had been exposed to more than 250 millisieverts, the newspaper reported.
The normal upper limit for workers at nuclear power plants is 100 millisieverts. TEPCO announced that a total of 102 employees had been exposed to more than that level.
TEPCO submitted a report to the Ministry of Health, Labor and Welfare on June 13 of a study into the 3,726 workers at the Fukushima No. 1 plant who worked between March 11, when the Great East Japan Earthquake struck, until March 31, the report added.
Radiation exposure levels for 2,367 workers who were tested were reported to the labor ministry. The results of the study for the remaining workers will be submitted by June 20, the newspaper said.
The eight workers found to have been exposed to more than 250 millisieverts were all male TEPCO employees.
The six employees who were added to the list in the latest report worked to restore equipment at the Fukushima plant as well as measure radiation levels.
