» Very high levels of cesium detected in the mud of reservoirs

Very high levels of accumulated radioactive cesium have been detected in the mud of hundreds of reservoirs used to irrigate farmland in Fukushima Prefecture, where agriculture is a key industry.

A joint survey by the prefectural government and a branch office of the farm ministry found that the levels exceed 8,000 becquerels per kilogram of soil in 576 reservoirs. In 14 of those cases, the level tops 100,000 becquerels.

The central government says that reservoirs, many of which are located in residential areas, are not covered by its decontamination program.

The survey covered 1,939 reservoirs, or slightly more than half of the 3,730 in Fukushima Prefecture for agricultural use.

Officials said 108 of the 576 contaminated reservoirs are in zones where residents were evacuated due to the March 2011 nuclear disaster.

The remaining 468 reservoirs are located outside the evacuation order zones and still supplying water to rice paddies and other farmland. Those areas are mainly located in the central part of the prefecture, including the cities of Fukushima and Date.
