NIGHTMARE OF JAPAN!



On date 11 Mac 2011, the dark day for Japanese. The most powerful earthquake recorded in Japanese history, magnitude until 8.9. This Tohoku earthquake triggered extremely destructive waves up to 38.9 meters that struck Japan. The tremors were the result of a violent uplift of the sea floor 80 miles off the coast of Sendai, where the Pacific tectonic plate slides beneath the plate Japan sits on. Tens of miles of crust ruptured along the trench where the tectonic plates meet. The earthquake occurred at the relatively shallow depth of 15 miles, meaning much of its energy was released at the seafloor. Regular aftershocks have already hit Japan as the Earth's crust continues to rupture along the Japan Trench. Those tremors are expected to be weaker and are less likely to produce another tsunami.

On March 12th, the government ordered evacuation within a 20-km radius around the nuclear power plant. Most residents had already left by then; however, approximately 1,500 patients remained in hospitals or nursing facilities. In the early morning of the 14th, these patients were transported to the SOSO Healthcare Center a screening point located 24 km north of the damaged power plant by buses, police vehicles and Japan Self Defense Forces transport. However, the limited capacity of the hospitals in Fukushima caused difficulty in reallocating these patients to the appropriate facilities. Many patientshad to wait for more than 24 hours, in the transport vehicles, in the cold weather without water or food. Unfortunately, at least 21 elderly patients died from hypothermia or dehydration.

As the situation in the 20-30-km zone around the plant deteriorated, the government instructed on March 15th that residents in this zone should remain indoors. However, there was still great confusion and fear of the effects of radiation, causing vital supplies such as food, water and gasoline as well as medical supplies to not be received in most of the area. The shortage of supplies had severe impacts on the hospitals and care facilities where approximately 1,700 patients remained. The local government eventually decided to move all of the patients out of the zone, which was completed by the evening of March 20th.

Initially, a value of 13,000 counts per minute, as measured by a Geiger-Müller counter, was used to indicate the need for evacuee decontamination. However, because of the disrupted water supply, very low temperature, and the need to cope with thousands of evacuees, this was increased to 100,000 counts per minute. At least 13 screening points were established by the night of March 14th, and more than 20,000 people had been screened by the 16th.Although a radiation emergency medical system had been developed, few had expected the magnitude of the damage to the nuclear power plant. Doctors and health care specialists voluntarily gathered in Fukushima to set up a radiation emergency medical management panel, which coordinated activities. Although these efforts were started with minimum resources, they were at the core of the subsequent medical responses dealing with the most difficult situation in Fukushima.

The first Japan’s nuclear Fukushima totally corrupted and destroyed. Death toll increased very fast, of which most serious ongoing INES-level 7 event. There more hazards from the nuclear power plant, under normal conditions, it can effect by radiation. The radiation release is very low, but potential risk of radioactive materials as that released by the Hiroshima atomic bomb. Discount the recent accident in Fukushima caused by earthquake and tsunami, two major historical serious accidents were triggered by two equipment malfunction and human errors.
