Timeline of the Fukushima Daiichi nuclear disaster pumps could be retrofitted to deliver concrete for that purpose. Prior to the elevation to level 7 by the Japanese authorities James Acton, Associate of the Nuclear Policy Program at the Carnegie Endowment for International Peace, was of the opinion that "Fukushima is not the worst nuclear accident ever but it is the most complicated and the most dramatic, was a crisis that played out in real time on TV. Chernobyl did not." A survey of radiation in seawater outside unit 2 shows radioactive isotope concentrations (iodine-131, caesium-134 and caesium-137) falling for the third consecutive day since the leak was
Radiation effects from the Fukushima Daiichi nuclear disaster used to produce bio-diesel, which could be used to produce electricity. According to director William Nolten the region had a big potential for the production of clean energy. Some 800,000 hectares in the region could not be used to produce food anymore, and after the disaster because of fears for contamination the Japanese people refused to buy food produced in the region anyway. Experiments would be done to find out whether camelia was capable of extracting caesium from the soil. An experiment with sunflowers had no success. High levels of radioactive caesium were found in 23 varieties of freshwater fish
