In Japan, more than 300 engineers raced against time to salvage the quake hit Fukushima atomic power plant making some progress in their efforts to cool down overheated spent fuel rods. Japanese officials said, power is being restored to two of the six reactors, raising hopes that their radio active contents could be cooled. But a sudden rise in pressure inside No.3 reactor sent jitters among the technicians who quickly prepared exigency plan to to release more radioactive gasses into the atmosphere to regulate it but the plans were aborted after the situation stabilized. Meanwhile, traces of radioactive iodine were detected in Tokyo and the surrounding Kanto region after an investigation of radioactivity in precipitation and dust was conducted following the nuclear crisis at the Fukushima Daiichi nuclear power plant. The government said, radioactive iodine was found in Tokyo, Saitama, Chiba, Yamanashi, Tochigi and Gunma prefectures. Seeking to dispel apprehensions of food and water contamination, officials said that radioactive materials in the air and tap water in Tokyo and five prefectures posed no threat to human health. The United Nations atomic watchdog said that there has been positive developments in the past 24 hours at Fukushima plant but that the overall situation remained very serious. Graham Andrew, a senior official of the International Atomic Energy Agency (IAEA), confirmed that measurements indicate that in some areas iodine has been detected in milk and freshly grown vegetables 'significantly above the levels set by Japan for restricting consumption of these food products. Meanwhile, the number of deaths in the March 11 earthquake and subsequent tsunami touched 8,133, while 12,272 people remained unaccounted for.
