Nuclear disaster, as known as nuclear and radiation accident, is defined by the International Atomic Energy Agency as an event that has led to the significant consequences to human, environment or the facility. The impact of nuclear disasters has been a topic of debate since the first nuclear reactors which were constructed in 1954. Also, it became a key factor in public concern about nuclear facilities. The official number of accident in nuclear power plants is 99 around the world.There were fifty-seven accidents have occurred since the Chernobyl disaster, and 57% of all nuclear related accidents have occurred in the United States. In my blog i will discuss some famous accidents; Hiroshima and Nagasaki followed by Chernobyl.
Hiroshima and Nagasaki:
This accident is the result of human’s cruelty among each other.On August 6, 1945, during World War II (1939-45), an American B-29 bomber dropped the world’s first deployed atomic bomb over the Japanese city of Hiroshima. The explosion wiped out 90 percent of the city and immediately killed 80,000 people; tens of thousands more would later die of radiation exposure. Three days later… another A-bomb on Nagasaki, killing an estimated 40,000 people. Here, humans made a bad use of nuclear power with the goal of hurting other humans rather than helping society to foward.
Chernobyl:
This disaster happened in 1986, in the Chernobyl Nuclear Power Plant locates in a town of Pripyat in Ukraine, which was uder the direct jurisdiction of the central authorities of the Soviet Union. The picture above shows the power plant after the nuclear disaster in 1986.
According to World Nuclear Association what caused it was simply a flaw within the reactor design. But this simple flaw is attributed to the “killing [of] 30 operators and firemen within three months and several further deaths later. One person was killed immediately and a second died in hospital soon after as a result of injuries received. Another person is reported to have died at the time from a coronary thrombosisc. Acute radiation syndrome (ARS) was originally diagnosed in 237 people on-site and involved with the clean-up and it was later confirmed in 134 cases. Of these, 28 people died as a result of ARS within a few weeks of the accident” (World Nuclear Association).
Following the accident, an are of 18 miles around the plant was closed and deserted from inhabitant.
