» Highly radioactive rainwater at Fukushima No.1 has likely leaked into the Pacific Ocean

Highly radioactive rainwater at the Fukushima Daiichi nuclear plant has likely leaked into the Pacific Ocean, according to TEPCO in the latest of a series of mishaps at the complex.

TEPCO said contaminated rainwater accumulating on the rooftop of the No. 2 reactor building is highly likely to have flowed into the ocean through a gutter. TEPCO learned of the possibility last May but failed to take measures immediately.

The level of radioactive cesium in the rainwater measured 29,400 becquerels per liter, while that of beta ray-emitting substances, such as strontium, measured 52,000 becquerels, according to the plant operator.

TEPCO said no major changes in radiation levels have been observed so far in the ocean outside a bay adjacent to the plant. It will take measures such as placing sandbags with materials that can absorb cesium to prevent further pollution.
