VIVAnews - Flashlight not really help illuminate a dark alley that they are going through. Plus the heavy burden of the oxygen tank and anti-radiation heat of the dress they wear, the situation is extremely uncomfortable.
Moreover, anti-radiation suit that was just the name alone. In fact, clothing is only to protect their little from radiation hazards.
But no complaints at all out of their mouths. In fact, they're betting their lives in that place. Every second, blast and radiation could have killed them. If you did not die instantly, many terrible diseases have been stalking them in the next 20-30 years, or even faster than that.
"We're doing a suicide mission. We accept this fate is like receiving a death sentence," so the contents of a short message to the family of a worker.
Were 200 workers at the Nuclear Power Plant (NPP) Dai-ichi Fukushima, who voluntarily choose to live in dangerous places.They tried to cool the nuclear reactor that is being spewed radiation within the limits of the unimaginable, and monitor it second by second.
They divided themselves into four shifts, each group of 50 people.They are often called, The Fukushima Fifty, 50 extraordinary people who are ready to die.
The company where they work, Tokyo Power Plant Co (Tepco) according to the New York Times, refused to disclose the identity of the workers who survive there. Tepco said they assigned only to pump sea water and keep the reactor cool. At the same time, to monitor radiation levels by using a small gauge that they bring, for measuring radiation in nuclear installations had been damaged.
More importantly, they are also tasked to find ways for nuclear core devices do not participate in the blast destroyed several times a few days ago. Because, if that happens, the result was fatal.Radioactive material can be spread on a large scale."Fighting fatigue and an empty stomach, we force ourselves to keep working," wrote one of his workers, Michiko Otsuki, on the Internet.
New York Times wrote, 200 workers who live this is not a brave young men who have the expertise and high knowledge about nuclear. Not all managers who are responsible for the operations of reactor. They are old men, workers and firefighters are a little longer - not until a half years - will retire.
So, even if they are exposed to radiation, they had hoped would not feel the disease that would undermine their body 20-30 years from now. They expect to have to call the divine because of old age, not due to leukemia, cataracts, and cancer.
Inside the nuclear plant, radiation levels reached 1,000 milliseverts (mSv) in one hour. It was unclear how much radiation was absorbed by the workers. Clearly, Japan and the United States has set a safe limit of radiation that a person can receive only 50 mSv in a year. For emergency situations such as this, the Japanese health ministry allows up to 250 mSv of radiation, it also has a maximum.
And the workers began dropping off, one by one. From that opted to stay on in power, five of them reported to have died, two missing and 21 others injured.
Millions of other livesWho's fighting for these workers, with their lives, are six nuclear reactors. Three have been exploded in the cooling process.Alternately, they monitor and pumping sea water to cool the reactor to prevent a nuclear catastrophe and claimed more human lives.
After the earthquake on the Richter Scale 9 and devastating tsunami hit the east coast of Japan on Friday, March 11, 2011, lives lost are beyond measure. According to a report from the National Police Agency of Japan as of March 16, 2011, the death toll reached 3676 people, injured 1990, and 7558 people are still reported missing in 16 prefectures which swept the tsunami. It is estimated, the numbers killed on the field much larger, and it is feared could reach tens of thousands of people.
And the loss of life will undoubtedly many times over if it fails cooled nuclear power plant, explode, and spread of the deadly radioactive substance came out.
Is a destructive earthquake vibrations nuclear infrastructure that consists of several buildings and six reactors. One of them is very vital: a giant diesel generators to keep the reactor cooling.
According to page JMA, tsunami early warning system to connect with some vital facilities in Japan. As soon as the warning lights, the system will automatically stop the train, elevator control, and regulate the rate of traffic. Well, then the system also automatically turn off electricity in nuclear reactors. Unfortunately, when that happens, the generator as a backup energy supplier is also damaged so that the flow of electricity dropped out altogether.Cooling failed and disastrous spies.
Three units of nuclear reactors that are still active now a center of world attention. These reactors are the reactor type hot water that require a certain temperature to operate safely.As reported by CNN, the fuel rod (fuel rods) normally work at temperatures 760 degrees Celsius. If the temperature is increased to more than 1,200 degrees Celsius, the fuel rods will be broken.Getting hot again, the fuel rods would melt. This melt would spread radiation, even to vaporize the reactor core. When this happens, horrible disaster would happen.
Within four days, three active nuclear reactor exploded. Reactor units one exploded on March 12, 2011. Unit three exploded two days later. And a day later, turn the unit two that exploded.
Japanese Prime Minister Naoto Kan was immediately declared an emergency situation-nuclear. A total of 170 thousand residents in up to 20 km radius were evacuated. Beyond that, the government urged them to stay indoors, close all air lines, and close the mouth with a towel.
Not yet clear what the exact cause of the explosion. However, according to the Associated Press, the explosion occurred when officers tried to cool the nuclear power plant reactor number one use of water. Apparently, the water that they gelontorkan create hydrogen when exposed to fuel rods. The amount of pressure to force the officer issued a hydrogen partial. However, when it actually released hydrogen mixed with oxygen and cause an explosion.
The level of radiation coming out from the damaged reactor was still spotty. According to MSNBC, on March 15, 2011 radiation can reach 11 900 mSv / hr. The experts from Indonesia who gathered at the Embassy in Tokyo, said that even radiation levels in areas near the reactor reached to 400 thousand mSv / hour.
Staff working even cat and mouse with radiation. If the peak, they step aside. If dropped, they advanced, doing things, as best he could.
Radiation carried by wind and even rumored to have reached Tokyo, a distance of 250 km from the NPP.
Head of the UN International Atomic Energy Agency (IAEA), Yukiya Amano, on Wednesday, has expressed very serious situation in Fukushima. Amano said the fuel rods in Unit 4, 5 and 6 have been exposed to the air and spread radiation. Various countries began calling on citizens to stay away from Fukushima nuclear power plant, at least up to a radius of 80 km.
Dangerous, indeed.However, nuclear has been the mainstay of Japan in meeting the electricity needs of their day-to-day. Data from the Federation of Electric Power Companies (FEPC) of Japan, this country operates 55 nuclear reactors generated electricity of almost 50 gigawatts.This energy contributes 34.5 percent of Japan's electricity needs.
In Japan, nuclear energy has become a strategic priority since 1973. For them, nuclear energy is a wise choice because the State Sakura did not have a lot of oil and gas resources.
Fukushima was not the first nuclear accident in Japan. In mid 1990, had been a few nuclear accidents, including accidents Tokaimura. After all, the Japanese government continues to firmly develop nuclear energy.
Chernobyl, Three Mile, FukushimaFukushima tragedy immediately reminded the world on two other nuclear tragedy.
In 1986, nuclear power plant in the Ukrainian Soviet Social Republic (now Ukraine), die suddenly power. As a result of overheating in the system, several explosions occurred.Culminating catastrophe when most of the nuclear core melt.
Radiation outside the blast area to 50 times greater than the radiation in Fukushima. High levels of radiation are spread throughout the western part of the Soviet Union, Eastern Europe, Western Europe, and North Europe. Most of the people in Ukraine, Belarus and Russia were evacuated, and 336 thousand people of whom chose not to return.
As a result of radiation exposure, 31 plant workers and firefighters who was then at the scene died in a matter of months. As many as 4,000 children and adults suffering from thyroid cancer after consuming milk contaminated radioactive. Reportedly, five million people affected by radiation and suffered a number of diseases, ranging from disability to cancer. Until recently, radiation levels at Chernobyl are still in a critical stage.
Based on the calculation of International Nuclear and Radiological Event Scale (Ines), the scale of the Chernobyl accident reached level 7, its highest level in a nuclear accident.
Previously, in 1979, a similar accident occurred at Three Mile Island, Pennsylvania, USA. Most of the nuclear core in nuclear power plants is also melted. Luckily, because the veil of the reactor was not damaged, then spread to the territory even though radiation is quite extensive, but tarafnya still relatively low. Three Mile event of nuclear accidents categorized two levels, namely a nuclear accident with a wide coverage area.
How to Fukushima?As NHK reported on Friday, Nuclear Industrial Safety Agency of Japan has raised the scale of radiation to a level 5 the highest level 7 in Ines Scale. This is because more than 3 percent of the nuclear fuel has been damaged and radioactive materials had leaked from the plant.
The situation has become increasingly desperate means at Embassy in Tokyo on Wednesday before the nuclear Indonesia gather 10 experts who on average are taking a doctorate at a university in the land of Sakura.
These experts, as contained on pages Embassy, ​​concluded that the accident in Fukushima reactor Units 1 to 4 are still in the scale of 4 Ines. That is, the scope of the accident is still around Fukushima nuclear power plant. However, this accident has destroyed the reactor building, pond cooling water reserves, and cause the fire in the reactor building that stores spent fuel.
Even if the nuclear core melting occurs, it is estimated that radiation will not be released by the Chernobyl incident. Reported by page of The Guardian, each reactor in Fukushima has 20 cm thick steel casing. The sheath was still wrapped again with concrete buildings. So, even if melted, the impact is not expected to be too severe.
Severe immeasurably their course inside the thick concrete casing, where workers are still struggling daredevil. They tried every means, all they could, to cool and monitor the reactor at the Fukushima nuclear power plant.
"I heard that he offered himself to be a volunteer, although he will retire and a half years. My eyes do not cry ... At home he is seen not the type that can perform large tasks. But today I am very proud of him. And I pray for his safety, "wrote someone on Twitter with @ NamicoAoto account.
One volunteer was his own father, who was 59 years old.
"Daddy, I beg you, come back safely."(Kd)• VIVAnews
