Radioisotopes In Chernobyl

A radioactive element does not have any stable isotopes, which means it may spontaneously degenerate, emitting alpha particles, beta particles and occasionally gamma rays. Some examples of radioactive elements are uranium, promethium and curium. Radioactive elements could be used either negative or positive.

Not many people fully know what happened at Chernobyl, or understand the effect it has had on today’s nuclear science. Chernobyl has been named as the largest man-made disaster ever recorded. Chernobyl is the most influential and important event during the 1980’s because it has completely changed how the world views anything nuclear by changing experimentation and usage of nuclear materials and power as a whole. It was extremely influential because it caused thousands of people to move out of their homes, while damaging nearby cities and countries and covering the surrounding area in radioactive smog, and is still a threat to surrounding cities and countries today. It also has caused the nearby area to be thriving with wildlife.

This quote, which I obtained from the newspaper The Guardian’s website, is from Sasha Yuvchenko, a former employee at the Chernobyl nuclear power plant. What he didn’t know at the time of the event he was describing was that he had just experienced the worst nuclear explosion in history.

On April 26, 1986, a nuclear reactor at the Chernobyl Nuclear Power Plant experienced a catastrophic meltdown that emitted radioactive material into the atmosphere, killing 31 people.

(1)At 1:23 am on April 26th 1986, 2 explosions devastated a nuclear power plant in Chernobyl. These explosions unleashed huge amounts of toxic radiation into the atmosphere. This radiation created a toxic plume of radiation that not only devastated Chernobyl but affected almost the whole of Europe. It started with total evacuation of the city, this started within 24 hours of the disaster and immediately an exclusion zone was in place. What the Ukrainian officials didn’t know at the time is just how serious this was. The wind blew the plumes created by this explosion one plume north and one plume west. The plumes were highly toxic and had been contaminated by the nuclear radiation. The radiation going west even reached north wales and many parts of Scotland and the south of Ireland. The radiation going north badly affected Finland, Sweden and parts of Norway. To put that into perspective the disaster released at least 100 times more radiation than the atom bombs dropped on Nagasaki and Hiroshima.

Many animals were affected by Chernobyl. The main reason they were affected was because they eat the grass that grows out of contaminated ground. The radiation also but new species like the Przewalski’s horse. The reason why the horse came is because that the populations of people went down since they went extinct to the area. That caused more animals to mutate. After the first few years, the levels of radioactive materials in plants and animals lowered quickly because of weather and decay. The levels have still gone down in the last ten years but not as quickly as it once

Cs-137 results from the natural decay chain of Uranium-235. Cs-137 has a half-life of 30 years which would account for the high levels after the decrease in discharge from Sellafield and is problematic due to ease with which it spreads throughout nature due to the high solubility of Caesium salts. This ease of spreading makes it difficult to clean up radionuclides such as Cs-137 and poses dangers to both aquatic wildlife and humans as ingesting the isotope can lead to exposure to gamma and beta radiation. Small amounts of Cs-137 were also released in the Chernobyl disaster in 1986 which would also correspond to the above background levels after the discharge from Sellafield decreased and would fit the timescale identified by the Sellafield

(MP1) What Chernobyl plant represented in 1980s and who is responsible for such a massive disaster

There have been lots of nuclear accident around the world. One of the accident that had a major impact on the world was the Chernobyl disaster. The disaster took place on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The disaster was caused by a reaction explosion induced by design faults and staff application errors. The accident took place in the course of scheduled tests to check the power supply mode in the event of external sources loss. Even after 10 days, explosions and ejections of radioactive substances continued. The release of radiation and radioactive substance polluted the places within 30 km of Chernobyl, and those areas have been closed for a long period of

Learning how the human health is being accidentally effected by showing the effects on human health. It tells about the effects of human’s health which are cancers, diseases, effects of pregnancies, Explaining about the effects of the population of people’s health. Showing statistics of children who have other kinds diseases they’re diagnosed with and explaining the caused from the accident that was in Chernobyl. Explaining the population of people who died or being diagnosed from the accident of the nuclear reactor. Also it explained about the effects of your body from the radiation.

The reading for this week was written by a Nobel Prize winner, Svetlana Alexievich. The author has compiled a variety of experiences into a paper bound book of “story-telling” literature. “Voices of Chernobyl” is a work of non-fictional literature that tells the devastating tales of a nuclear disaster. Within the pages of 67-104 their are words spoken by victims of the nuclear disaster. First off their is the story of a woman, a farmer, whose struggle is never-ending. She speaks of her farm and how the goods she once survived on had been rendered useless from the radiation. For example she mentions her cows slowly diving and their milk turning into nothing more then a white powder. The female farmer compares her experience with Chernobyl to

Naturally occurring radionuclides of terrestrial origin have existed in the earth’s crust since its origin. These radionuclides have longer half-lives, for example, K-40 with half-life of 1.248×109 years, U-238 with half-life of 4.468 ×109 years and Th-232 with half-life of 1.405×1010 years. These species have survived since the time of creation and have subsequently decayed to attain a state of stability in which they produce ionizing radiations. The levels of radioactivity on earth vary from place to place. In some places they vary within narrow limits, but in some places deviations from normal levels are wider because of abnormally high levels of radioactivity (Allisy- Roberts, 2005). The distribution of naturally occurring radionuclides

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

The Chernobyl accident was a disastrous nuclear event that happened on 26th April 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The Chernobyl disaster is classified as a level 7 event according to the International Nuclear Event Scale (only two events have been classified this high in the past) and has caused damages that consist of the cost of 500,000 workers and 18 billion rubles, 31 deaths according to the Soviet casualty count (this is still being disputed) and between 4000-27000 affected future deaths due to radiation exposure [G1].

The Chernobyl incident continues to demonstrate the risks involved with nuclear power, as well as the consequences of any failure. Simple human error led to a chain reaction that caused the reactor core to melt down. The resulting explosion spewed clouds of radiation into the atmosphere that quickly spread. Kasperski states, “The explosion of reactor Unit 4 on April 26, 1986 led to heavy radioactive contamination of regions of Ukraine, Belarus, and Russia” (Kasperski 44). With no way of containing the radiation, the toxic cloud quickly spread throughout Europe. Nazaryan explains, "The toxic cloud that enveloped much of Europe....contained: cesium-137, iodine-131, zirconium-95...." (Nazaryan 4). What made matters worse is that the public didn’t know about the accident until two days after the explosion occurred. This resulted in thousands of civilians unknowingly exposing themselves to potentially life-threatening levels of radiation. While the radioactive cloud eventually dispersed into the atmosphere, the same cannot be said about the radiation absorbed by the ground
