Waste water discharged into Tokyo Bay from a cement plant has been found to contain radioactive cesium at much higher levels than the government-set limit for disposal.

The plant in Chiba Prefecture, east of Tokyo, uses ash from incinerators in the prefecture to produce cement.

The Chiba government says the plant operator checked waste water discharged from the plant into Tokyo Bay once in September and once in October.

It found radioactive cesium at levels of 1,103 becquerels per kilogram, and 1,054 becquerels per kilogram respectively.

The levels are 14 to 15 times higher than the limit set by the country’s Nuclear Safety Commission.

The water had been used to clean filters which remove toxic materials from ashes.

The operator stopped discharging the waste water on Wednesday. The prefectural government has launched a survey of the seawater of Tokyo Bay near the plant.
