There was a recent report in Russian Times that
A record high level of radioactive cesium has been found in groundwater beneath the crippled Fukushima No. 1 nuclear power plant, it operator TEPCO revealed…On February 13, Tokyo Electric Power Co. reported 37,000 becquerels of cesium-134 and 93,000 becquerels of cesium-137 were detected per liter of groundwater sampled from a monitoring well earlier that day…Water samples were taken from the technical well, located next to the second power unit, some 50 meters from the coast. These figures (the total reading) are the highest of all the cesium measurements taken previously.
The Nuclear Regulation Authority (NRA) accused TEPCO of lacking basic understanding of measuring and handling radiation almost three years since the reactor meltdowns at the Fukushima No. 1 nuclear power plant.
If the ground water is this radioactive 50 meters from the coast, then it seems that it is only a matter of time before radioactive ground water is spilling into the sea. Further, this report is mentioning only cesium, and there are many other radioisotopes produced by a nuclear reactor in melt down. Since the NRA accused TEPCO of lack of basic understanding, do they, the NRA, have any power to influence TEPCO’s behavior?
