The damaged Fukushima Daiichi nuclear power plant immediately became the center of human and environmental concerns, amid leaks of radioactive material and the risk of reactor meltdown. Emergency crews began the struggle to contain the crisis and prevent widespread contamination.
Work on containing the crisis at the Fukushima Daiichi complex is hampered because the level of radioactive iodine found in water inside exceeds 10,000 times the safety standard, officials say.
Tsunehisa Katsumata, chairman of the Tokyo Electric Power Co., expresses deep remorse for the problems at the Fukushima plant. Meanwhile, authorities are considering ways to limit radiation damage, including placing a tarp over the reactors and pumping radioactive water into a barge.
