Tokyo Electric Power Co. said it’s investigating the cause of a spike in radiation levels in drainage water that it believes subsequently leaked into the Pacific ocean from its wrecked Fukushima Dai-ichi nuclear plant north of Tokyo.
The radioactivity increase was detected on Sunday, the company said in an e-mail yesterday. No workers were exposed and tests of radiation levels in sea water in the port adjacent to the plant showed no significant increase, the company said.
