TOKYO - Environmental group Greenpeace on Thursday slammed Japan's "continued inadequate response" to the nuclear disaster at a power plant after new data showed seaweed radiation levels 50 times higher than official limits.
The new information raised "serious concerns" about long-term risks from contaminated seawater, it said, more than two months after the Fukushima-Daiichi plant was destroyed by an earthquake and tsunami.
"In contrast, Japanese authorities claim that radioactivity is being dispersed or diluted and are undertaking only limited marine radiation monitoring," it said.
