Nuclear Accident Of Goiania, Brazil

Nuclear Accident Of Goiania, Brazil

Radioactive contamination in Goiania was a case of radioactive infection that occurred in the Brazilian city of Goiania on September 13, 1987. The result of the Goiania nuclear disaster was the rapid death of four people and the chronic radiation sickness of several others. .

In 1987, a part of a radiotherapy unit containing a cesium-137 radioactive isotope in the form of cesium chloride was stolen from a hospital abandoned by marauders, after which it was discarded.

After a while, the piece was found in a landfill and attracted the attention of the landfill owner, Devara Ferreira, who then brought the medical source of radiation to his home and invited neighbors, family and…

How are nuclear accidents classified?

How are nuclear accidents classified?

A nuclear accident is an accident that causes or could cause the release of radioactive material.

There are many ways to classify this type of event. In a very simple first classification we could distinguish between civil nuclear accidents and nuclear accidents of military origin.

Within the scope of civil nuclear technology, not all nuclear accidents occur in nuclear power plants. Nuclear disasters can be generated in any field that works with this technology: hospitals, research centers, etc.

Another way to classify nuclear accidents is according to their severity and the consequences generated. In this sense, the INES scale was created.

Nuclear Power After World War II

Nuclear Power After World War II

The key moment for the future of the history of nuclear energy appears after the end of World War II. At this time the United States held war supremacy due to its considerable atomic potential. The existing complexity around the war and civil issues of nuclear energy required the establishment of a legal articulation for civil applications in the country, and international regulation at all levels.

Although several international meetings took place, the United States is reluctant to lose his role, and the President Truman stated: "We must constitute ourselves as guardians of this new force to prevent its deadly work and direct it for the good of humanity [...]. "

Chalk River Nuclear Accident - Ontario, Canada

Chalk River Nuclear Accident - Ontario, Canada

Chalk River Laboratories is a facility located in Ontario, Canada. During the 50s, these facilities suffered two major nuclear accidents.

The first Chalk River nuclear disaster occurred in 1952 when the NRX reactor suffered a violent explosion that destroyed the reactor core. The explosion of the reactor caused the fusion of nuclear fuel. The descent of the control rods failed so that nuclear chain fission reactions could not be stopped. As a result, thousands of radioactive particles were released into the atmosphere.

The second nuclear accident at the Chalk River facilities took place 5 years later. In this case, several uranium nuclear fuel rods overheated…

Natural Uranium

Natural Uranium

In a broad sense, natural uranium refers to natural uranium resources (including uranium ore and uranium contained in seawater) and those that have the same isotopic composition as natural uranium. In a strict sense, it refers to metallic uranium and its compounds (oxides, fluorides, carbides, nitrides). When used in comparison to enriched uranium and depleted uranium, it is used in this limited sense.

Natural uranium extracted from uranium contains an approximate proportion of 99.3% of isotope 238, and 0.7% of isotope 235. Of these, uranium 235 radioisotopes can be used as nuclear fuel in a nuclear reactor.

At the beginning of the 21st century, the type of reactor…

Chooz Nuclear Power Plant, France

Chooz Nuclear Power Plant, France

The Chooz nuclear power plant is a nuclear power plant in Chooz, France. That is, its function is to harness the nuclear energy of nuclear fission reactions to generate electricity. The nuclear power plant is located in a meander of the Maas. Also, the nuclear facility is located on the Pointe de Givet, about 25 km from the Belgian Dinant.

The first of the two nuclear reactors available to the nuclear plant was built in the 1960s with the participation of Belgian industry. In this way, the location near the French-Belgian border is explained in part.

More than 700 EDF employees work with over 200 subcontractor employees at the Chooz nuclear power plant. During…
