Radioactive material may have leaked from tunnel

Japan's nuclear regulators suspect that contaminated wastewater may be seeping into the sea from an underground utility tunnel at the Fukushima Daiichi nuclear plant.

Highly radioactive substances have been detected in coastal observation wells on the plant's premises, and in nearby seawater, since May this year.

The plant's operator, Tokyo Electric Power Company, admitted for the first time on Monday that wastewater is leaking into the sea.
