Perancis: Serius nahas nuklear Jepun di paras enam, hampiri kes Chernobyl

Perancis: Serius nahas nuklear Jepun di paras enam, hampiri kes Chernobyl

Chernobyl Disaster
PARIS, 15 Mac — Pihak berkuasa keselamatan nuklear Perancis hari ini berkata keseriusan nahas nuklear loji Fukushima Daiichi di Jepun, milik Tokyo Electric Power, hari ini mencecah paras enam.

Skala antarabangsa yang digunakan ialah satu hingga tujuh.
Semalam, ASN memutuskan malapetaka itu di tahap lima atau enam.
Loji itu terletak 240 kilometer ke utara Tokyo.

Chernobyl Disaster
Paras tujuh hanya digunakan sekali iaitu iaitu membabitkan loji Chernobyl di Ukraine pada 1986.

Nahas di loji tenaga nuklear Three Mile Island di Amerika Syarikat pada 1979 hanya diklasifikasikan sebagai lima.

Awal hari ini Perdana Menteri Jepun mengesahkan kebocoran radioaktif di loji itu manakala hampir 200,000 orang dipindahkan. — Reuters

Chernobyl Disaster

The Chernobyl disaster was a nuclear accident that occurred at the Chernobyl Nuclear Power Plant in modern day Ukraine. On April 26, 1986, operators at the power plant conducted a scheduled test on the electric control system of one of the nuclear reactors. For an amount of time the reactors safety system was turned off. The reactor was also operating under improper and unstable conditions. These factors, along with faulty actions of some operators, caused an uncontrollable power surge to occur in nuclear reactor number four. This caused a fatal meltdown in the reactor. A chain reaction of nuclear explosions occurred that severely damaged the reactor building, completely destroyed the reactor, and caused the release of massive amounts of radioactive material. The fallout was propelled into the atmosphere and over an extensive geographical area. The nuclear fires burned at the Chernobyl Nuclear Plant for ten straight days.

The Fallout

The nuclear plume drifted over large parts of the western Soviet Union, Eastern Europe, Western Europe, and Northern Europe. Nuclear rain fell as far away as Ireland. Large areas in Ukraine, Belarus, and Russia were badly contaminated, resulting in the evacuation and resettlement of around 400,000 people. The event is widely considered to be the worst nuclear power plant disaster in history. It is the only level 7 event on the International Nuclear Scale. After the accident, millions of people were exposed to radiation from the nuclear cloud. A mass amount of radioactive material was deposited into the ground, plant, and animal life. The contamination of food and farmland became a major issue in surrounding areas.

A large collection of children were exposed to radioactive iodine after drinking contaminated cow’s milk. It has been estimated that five million people are living in areas with trace amounts of contamination caused by the Chernobyl accident. It remains unclear how many people developed cancer directly because of the incident. A 2005 report prepared by the Chernobyl Forum indicated that around 4,000 of the most highly exposed people have developed malignant tumors. People have challenged these results, claiming many more deaths. In comparison to the nuclear bombing of Hiroshima, four hundred times more nuclear fallout was recorded during the Chernobyl accident.

The zone of alienation is the 30 km/19 mi exclusion zone surrounding the site of the Chernobyl nuclear reactor disaster. It is located in the northernmost parts of Kiev Oblast and Zhytomyr Oblast of Ukraine, and adjoins the country’s border with Belarus. Approximately 3,000 workers are employed within the Zone of Alienation. Many people living in this area of the world have reported seeing various types of strange animal mutations. A few scientific studies have been conducted that suggest albinism is forming in swallows.

The wildlife populations in the zone of alienation appear to be flourishing due to significant reduction of human impact. Populations of traditional Polesian animals, such as wolves, wild boar, red deer, moose, and beaver have been multiplying and expanding outside the zone. Even extremely rare lynx have appeared, and there are reports of brown bear tracks, an animal that has not been seen in the area for several centuries. The rivers and lakes in the zone pose a significant threat to surrounding areas. This is due to the spread of polluted silt during the flood season. Until a significant scientific study can be performed in the area, we will not know for sure what creatures are lurking in the zone of alienation.
