A tiny amount of radioactive water has leaked from a storage tank at the crippled Fukushima No. 1 nuclear power plant.
A tiny amount of radioactive water has leaked from a storage tank at the crippled Fukushima No. 1 nuclear power plant.
Tokyo Electric Power Co., the operator of the plant, said May 1 that about 40 milliliters of water was found under a storage tank holding radiation-contaminated water. The water is believed to have leaked from the tank.
Sandbags were placed around the tank to prevent water from spreading to other areas.
A TEPCO official said a worker came across the wet patch measuring 20 centimeters square at 9:30 a.m. on May 1.
Seventy millisieverts per hour of beta ray-emitting radioactivity were detected on the surface where the water had leaked.
