TOKYO, Japan – A damaged Japanese nuclear plant is suspected to be leaking radiation-contaminated water into the Pacific Ocean, Tokyo authorities were quoted as saying by news reports Thursday, July 11.
The Nuclear Regulation Authority (NRA) said it is “highly suspected” that radioactive water at the Fukushima Daiichi Nuclear Power Station had seeped into the ground and contaminated the sea, the Kyodo News agency reported.
“We must find the cause of the contamination and put the highest priority on implementing countermeasures,” said Shunichi Tanaka, the head of the NRA.
Plant operator Tokyo Electric Power Co said this week that levels of radioactive material in groundwater had risen sharply at the complex.
A survey showed that levels of cesium-134 in groundwater at an observation well had jumped to 11,000 becquerels per litre on Tuesday, from 99 per litre on Friday, the operator said.
The levels of cesium-137, another radioactive isotope, had also soared, to 22,000 becquerels per liter on Tuesday, July 9, from 210 per liter on Friday, it said.
Tokyo Electric has said it did not know what had caused the jump. – Rappler.com
