摘要: On 11th March 2011, the high magnitude 9.0 earthquake occurred about 130 km off eastern Pacific coast of Japan’s main island Honshu, followed by a large tsunami. These events caused loss many lives and huge damage. One consequences was station blackout (total AC electric power) at Fukushima Dai-ichi nuclear power plant (FD-NPP). The plant, which is operated Tokyo Electric Power Company (TEPCO). developed into disaster leaving four six FD-NPP units heavily damaged [21]. radioactivity released atmosphere from reactor cores dominated volatile fission products as result containment venting (reducing gaseous pressure), hydrogen explosions discharge coolant water sea [3, 5, 6]. radioactive materials were dispersed mainly in northern hemisphere. Until early May, levels activity concentration remained significant throughout whole hemisphere, but mid June 2011 most stations International Monitoring System (IMS) CTBTO (Comprehensive Nuclear-Test Ban Treaty Organization) network returned to background level [20]. emission radionuclides started on 12th vicinity NPP [4].
