On March 11, 2011natural destruction raged the small island nation of Japan. With a massive earthquake and tsunami caused equipment damage that eventually lead to destruction of Fukushima Daiichi nuclear power plant. During the earthquake and tsunami three nuclear reactors were destroyed. The 9.0 magnitude earthquake caused damage all over the island and still 2 years later Japan is struggling to get back on its feet. People were forced to leave their homes and possessions behind as the Japanese government tried to correct the damage done by the tsunami and earthquake. With not only the country hurting, its natives hurt for normalcy. The road to recovery is a long one but one must look at the steps taken so far to return Japan back to where it once was. The earthquake and subsequent tsunami, resulted in massive radioactive contamination on the mainland. In April, the Japanese government chose to drastically increase its official “safe” radiation exposure levels from 1 mSv to 20 mSv per year – 20 times higher than the US exposure limit. With this change it allowed the government to downplay the dangers of the fallout and avoid evacuation of many badly contaminated areas. Only a few months later in November, the Japanese Science Ministry reported that long-lived radioactive cesium had contaminated 11,580 square miles however,4,5000 square miles, almost the same size of Connecticut, was found to have radiation levels that exceeded Japan’s allowable exposure to radiation. Land within 12 miles of the destroyed nuclear power plant, encompassing an area of about 230 square miles, and an additional 80 square miles located northwest of the plant, were declared too radioactive for human habitation. Within this 310 evacuation area it is est... ... middle of paper ... ...l bounce back from this and move on to big and better things. Works Cited "About."

...r. Iodine 131, another radioactive element, can dilute very quickly in the air, but if it is deposited on grass eaten by cows, the cows then re-concentrate it in their milk. Absorbed into the body's thyroid gland in a concentrated dose, Iodine 131 can cause cancer. In the Chernobyl disaster, the biggest health effect has been cases of thyroid cancer especially in children living near the nuclear plant. Therefore, because of the Chernobyl disaster we know to test the grass, soil, and milk for radiation. Also, an evacuation of the Chernobyl area was not ordered until over 24 hours after the incident. Japanese authorities evacuated 200,000 people from the area of Fukushima within hours of the initial alert. From the mistakes and magnitude of the disaster at Chernobyl, the world learned how to better deal with the long and short term effect of a Nuclear Fallout.
Early in the morning of April 27, 1986, the world experienced its largest nuclear disaster ever (Gould 40). While violating safety protocol during a test, Reactor 4 at the Chernobyl power plant was placed in a severely unstable state, and in a matter of seconds the reactor output shot up to 120 times the rated output (Flavin 8). The resulting steam explosion tossed aside the reactor’s 1,000 ton concrete covering and released radioactive particles up to one and a half miles into the sky (Gould 38). The explosion and resulting fires caused 31 immediate deaths and over a thousand injuries, including radiation poisoning (Flavin 5). After the accident more than 135,000 people were evacuated from their Ukrainian homes, but the major fallout occurred outside of the Soviet Union’s borders. Smaller radioactive particles were carried in the atmosphere until they returned to earth via precipitation (Gould 43). The Soviets quickly seeded clouds to prevent rainfall over their own land, so most of the radioactivity burdened Western Europe, Scandinavia, and the Atlantic and Arctic Oceans (Flavin 12). This truly international disaster had far reaching effects; some of these were on health, the environment, social standards, and politics.

Countless engineering disasters have occurred in this world, many civilians lost their lives due to corrupted constructions. The most fatal and deadly engineering disaster that took place in our history was the Chernobyl disaster. The Chernobyl catastrophe was a nuclear setback that happened at the Chernobyl Nuclear Power Plant in on April 26, 1986. It is seen as the most recognizable terrible nuclear power plant cataclysm ever. A nuclear crisis in one of the reactors caused a fire that sent a cluster of radioactive consequence that on the long run spread all over Europe.
The nuclear explosion over Nagasaki affected an area of approximately 110 km², of which 22 is water and 84 were partially populated.
Scenario: Sirens blaring in the middle of the night and chaos erupting from every direction. At precisely 1:21 a.m. on April 26th 1986 in Chernobyl, in a city with upwards of fifty thousand people located next to Pripiat River, a reactor exploded and released up to thirty to forty times the radiation of the Hiroshima and Nagasaki bombing. But one would never think of that a disaster of this magnitude would ever happen because the plant workers are among some of the most highly trained in the universe. Millions of people had to suffer from the greatest nuclear disaster ever known to mankind.
I. (Gain Attention and Interest): March 11, 2011. 2:45 pm. Operations at the Fukushima Daiichi Nuclear Power Plant continued as usual. At 2:46 pm a massive 9.0 earthquake strikes the island of Japan. All nuclear reactors on the island shut down automatically as a response to the earthquake. At Fukushima, emergency procedures are automatically enabled to shut down reactors and cool spent nuclear fuel before it melts-down in a catastrophic explosion. The situation seems under control, emergency diesel generators located in the basement of the plant activate and workers breathe a sigh of relief that the reactors are stabilizing. Then 41 minutes later at 3:27 pm the unthinkable occurs. As workers monitored the situation from within the plant, citizens from the adjacent town ran from the coastline as a 49 foot tsunami approached. The tsunami came swiftly and flooded the coastline situated Fukushima plant. Emergency generators were destroyed and cooling systems failed. Within hours, a chain of events led to an explosion of reactor 1 of the plant. One by one in the subsequent days reactors 2, and 3 suffered similar fates as explosions destroyed containment cases and the structures surrounding the reactors (Fukushima Accident). Intense amount...

There is a range of safety concerns in regards to nuclear power with one of these being the effects of radiation resulting from a nuclear accident. Research shows that there is a link between exposure to radiation and the development of cancer (Zakaib 2011) whist Preston (2012) express’s concerns that people exposed to radiation may not be able to see the effects of radiation exposure for several years as was the case in Chernobyl. Furthermore, people are unable to move back into the vicinity of reactors that have been involved in an incident due to their fear of radiation as is the chase in Fukishima (Cyranoski & Brumfiel 2011) and in the areas surrounding Chernobyl (Berton 2006). Governments are increasingly becoming more stringent in the levels of radiation in which people are exposed to with this evident in Fukishma, where the Japanese government evacuated people living within a 30km radius of the plant (Evacuation Orders and Restricted Areas n.d.). As a result of nuclear accidents and the resulting radiation, support for nuclear power has diminished due to safety concerns.
For them, the 2011 nuclear crisis in Japan and the multiple radioactive water leakages from Ranger mine (Statham, 2011) constituted several recent examples of such dangers. They firmly held that scientific research denying the likelihood of nuclear waste contamination would be essentially biased (Gundjehmi Aboriginal Corporation,

While the early warning saved thousands of people, the Japan’s Meteorological Agency underestimated this earthquake as the subduction zone of Japan should not produce the magnitude 9.0 quake (Oskin, 2013a). The Tohoku Earthquake and its tsunami approximately killed 16 thousand people, injured 6 thousand people and around 3 thousand people were missing. Most people died from drowning. Around 300 thousand buildings, 4000 roads, 78 bridges, and many more were affected by the earthquake, tsunami, and fires from leaking oils and gas. Electricity, telecommunication, and railways were severely damaged. The debris of 25 million tons was generated and carried out to the sea by water (BBC News, 2012). The country’s authorities estimated more than 309 billion US dollars of damages. Landslides occurred in Miyagi and liquefaction in Chiba, Tokyo, Odaiba, and Urayasu (USGS, 2013). Furthermore, the tsunami destroyed protective tsunami seawalls. Approximately 217 square miles of Japan covered in water (Oskin,
The energy industry is beginning to change. In today’s modern world, governments across the globe are shifting their focuses from traditional sources of power, like the burning coal and oil, to the more complex and scientific nuclear power supply. This relatively new system uses powerful fuel sources and produces little to no emissions while outputting enough energy to fulfill the world’s power needs (Community Science, n.d.). But while nuclear power seems to be a perfect energy source, no power production system is without faults, and nuclear reactors are no exception, with their flaws manifesting in the form of safety. Nuclear reactors employ complex systems involving pressure and heat. If any of these systems dysfunctions, the reactor can leak or even explode releasing tons of highly radioactive elements into the environment. Anyone who works at or near a nuclear reactor is constantly in danger of being exposed to a nuclear incident similar to the ones that occurred at the Chernobyl and Fukushima Daiichi plants. These major accidents along with the unresolved problems with the design and function of nuclear reactors, as well as the economic and health issues that nuclear reactors present serve to show that nuclear energy sources are not worth the service that they provide and are too dangerous to routinely use.
The biggest damage is the radiation exposal to the people. 530,000 local recovery workers were exposed the radiation, the effective dose is same as fifty years of natural radiation exposure (IAEA, 1996). 31 nuclear power staffs and emergency workers were died by direct effect, and the Chernobyl Forum anticipates the total num...
There was a multitude of causes of the disaster in Japan. The first cause was a 9.0 magnitude earthquake that occurred off the coast of Japan. Japan is located in “The Ring of Fire,” an area in the Pacific Ocean that has multiple faults and earthquakes (Pedersen 13). Tectonic plates shifted off the North Pacific coast of Japan and created a massive earthquake. The next cause was a thirty-three foot wall of water that swept over cities and farmland in Japan (Branigan 2). Martin Fackler, a journalist, stated, “The quake churned up a devastating tsunami” (Fackler 3). The tsunami reached speeds of 497 miles per hour while approaching Japan (Fackler 3). The third and final reason of the disaster was that the cooling systems at multiple nuclear power plants failed. At Fukushima, a nuclear power plant in Sendai, Japan, the radioactive rods began to overheat due to the absence of water, which cools it. Explosions occurred at three of the reactors, which spewed radiation into the air (“Comparing nuclear power plant crises”). In conclusion, the earthquake, tsunami, and nuclear power plant issues were the causes of the disaster in Japan, but they also had a myriad of effects.
