Workers at the crippled Fukushima No. 1 nuclear plant were ordered to cover their dosimeters with lead plates to keep radiation doses low enough to continue working under dangerous conditions, the Asahi Shimbun has learned.
Some refused the orders. Others raised questions about their safety and the legality of the practice. But the man in charge, a senior official of a subcontractor of Tokyo Electric Power Co., warned them that they would lose their jobs--and any chance of employment at other nuclear plants--if they failed to comply.
The pocket-sized dosimeters sound an alarm when they detect high radiation levels. A worker who has been exposed to an accumulated dose of 50 millisieverts within a year must stop working and stay away from the area for a certain period of time.
