Radioactivity definition

Radioactivity definition

Radioactivity defined as the spontaneous emission of particles (alpha, beta, neutron) or radiation (gamma, K capture), or both at the same time, from the decay of certain nuclides that these particles are, due to an adjustment of their internal structure.

Radioactivity can be natural or artificial. In natural radioactivity, the substance already has radioactivity in the natural state. In artificial radioactivity, the radioactivity has been induced by irradiation.

A radionuclide is all the radioactive cores of the same kind. All radioactive cores forming a radionuclide…

History of nuclear energy

The Greek philosopher Democritus of Abdera was the first in history to give a definition of atom as the smallest constituent of matter, in the V century B.C. The term "atom" is a Greek word that means "not divisible". But later, with the arrival of nuclear fission it's possible to split atoms to…

Radionuclide definition

A radioactive nuclide radionuclides or radionuclide is an unstable nuclide and thus degenerates emitting ionizing radiation. Although some physicists sometimes commonly used to designate the palabraradioisótopo however, it should be noted that strict or formal language of physics and nuclear technology is flawed as a nuclide and an isotope are not the same. When a radionuclide emits radiactividadalcanza a more stable state, which requires less energy than before, and generally becomes a different nuclide (or in the same,…

Nuclear power in Chile

Nuclear power in Chile appears for the first time in 1964 with the approach of the project that made Dr. Cruz-Coke.

Chilean Commission of Nuclear Energy

The most important organization is the CCHEN Chile (Chilean Commission of Nuclear Energy) which is responsible for everything that is related to the peaceful use of nuclear energy . (Since nuclear energy was initially used for military purposes).

The CCHEN, has two nuclear reactors for research,…

Fukushima nuclear accident

Fukushima nuclear accident

On March 11, 2011 in Fukushima occurred one of the worst nuclear accidents in history after the Chernobyl nuclear accident.

A 8.9 magnitude earthquake off the northwest coast of Japan and a subsequent tsunami severely affected Dahiichi Fukushima nuclear plant on the northeast coast of Japan.

At the time of the nuclear accident at the Fukushima reactors had 6. Reactors 1, 2 and 3 were operating while nuclear reactors 4, 5 and 6 were unemployed for maintenance.

After the earthquake Fukushima reactors that were still running is automatically stopped. To cool the reactors,…

Transport and management of nuclear waste alamcenamiento low and intermediate level

The term nuclear waste management as a set of activities that lead to reuse your desaparicióno your neutralizacióny evacuacióna right places, ensuring long-term safety.

The storage of nuclear waste in low and intermediate level is based on the filing of natural and artificial barriers between these nuclear waste and the environment, so they are perfectly isolated long enough until their radioactivity decay to harmless levels. To store the radioactive waste of low and medium activity generated in Spain, has ENRESA Storage Center The Cabril in the province of Cordoba,…

Chernobyl nuclear accident

The nuclear accident in Chernobyl (1986) is by far the most serious nuclear accident in the history of nuclear energy. It was classified as level 7 (severe nuclear accident) of the INES scale, the highest value. Although it is the same level at the Fukushima nuclear accident was classified, the consequences of the Chernobyl accident were still far worse.

The Chernobyl nuclear power plant is located near the town of Prypyat, 18km from the city of Chernobyl.

At the time of the Chernobyl nuclear power plant accident provided 4 reactors in operation and two more were under construction.
