Tokyo Electric Power Co. (TEPCO) reported its second high radiation reading in as many days at the crippled Fukushima nuclear plant in Japan.
Bloomberg reported the utility detected 5 sieverts of radiation per hour inside the Unit 1 reactor building. On August 1, readings around the main exhaust between units 1 and 2 read 10 sieverts of radiation per hour. The readings will keep workers from entering the areas.
The 10 sieverts of radiation on Aug. 1 was the highest the Geiger counters were capable of reading, Bloomberg said. As a result, the level could have been higher.
The latest high radiation readings may be coming from materials released after attempts shortly after the crisis began in March 2011 to release pressure in containment vessels and vent hydrogen gas.
TEPCO still needs to investigate other areas for high radiation levels before a cold shutdown and cleanup scheduled for January, the article said.
