Tokyo Electric Power Company says workers are now building a steel fence around the water inlets and outlets of the Fukushima Daiichi plant.

They are attempting to block highly radioactive isotopes from getting out into the currents of the Pacific Ocean. They are also using silt fences.

One report says the steel fences are seven steel sheets thick, and the fence will cover an area 120 meters (393 feet) wide.

Recently officials admitted that radiation reports were faulty because the radiation levels are so high that monitoring devices are basically wigging out, and unable to give accurate readings. They stopped short of saying the levels are so high that they peg their meters.

They are hoping to use a UAV (drone) to monitor levels over the plant. It depends on the weather, unmanned aerial vehicles need good weather to fly.
