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…

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,…

Scale INES - International Nuclear Event Scale

The INES scale is a tool to quantify the severity of a nuclear and radiological event (either accidents or nuclear incidents).

INES is the acronym for International Nuclear Events Scale.

It is used worldwide to systematically inform the public about the importance of the nuclear and radiological events from the point of view of safety.

Therapeutic nuclear medicine

The specialty of nuclear medicine that uses ionizing radiation for the treatment of malignant tumors is known as radiation therapy.

When radioactive unsealed sources speak of metabolic radiotherapy, which involves injecting or to ingest a relatively large dose of a radioactive substance in liquid form, so that it accumulates in the organ to be treated, which acts through used of radiation emitted on fabrics in contact therewith, producing the desired destruction of tumor cells effects.

This type of therapy is used to treat hyperthyroidism, thyroid cancer, bone metastases from…

Mayak nuclear accident

Mayak nuclear accident

Mayak is one of the highest points of the planet with radioactive contamination. It is also conce as Mayak Production Association (Russian: Маяк производственное объединение ). These are the names by which a complex known nuclear facilities between the cities of Kaslo and Kyshtym in laprovincia Chelyabinsk, Russia.

The Mayak nuclear accident is little known because the Soviet authorities tried to hide for 30 years nuclear leaks have been occurring.

History of Mayak nuclear plant

Nuclear accidents

Nuclear accidents

In nuclear energy, we refer to nuclear accident to those incidents that emit a certain level of radiation, which could harm public health.

Nuclear accidents are classified as nuclear accidents and incidents depending on the severity´s level. In this classification nuclear accidents and radioactive accidents are included. To understand the difference between these two types of accidents, a nuclear accident could be the failure of a reactor of a nuclear power plant and a radiation accident could be when pouring a radiation source to a river.

Despite the known nuclear…

Chernobyl nuclear accident

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.

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 waste

Nuclear waste

One of the main problems in the use of nuclear energy is the management of nuclear waste as it is very dangerous and difficult to eliminate.

What is done with nuclear waste?

Nuclear waste is one of the main problems related to nuclear energy. If these wastes are not treated properly, they are highly hazardous to the population and the environment.

Radioactive waste can be classified according to its physical and chemical characteristics and by its activity.

Classifying them by their activity we have:

  • High-level nuclear waste, composed of elements of…

Nuclear energy and the environment

Nuclear energy and the environment

Populritat Although nuclear energy is very low there are applications of nuclear energy for works for the environment.

What is the relationship between nuclear energy and the environment?

To reduce pollution in the environment, we need to know where and how much to find these pollutants, the causes of contaminacióny the right solution to prevent it from spreading.

The main source of pollution is found in human activities contributing largely to the increase in pollutants, growth poblacióny industrial technological developments.

At present, the biggest…

Plutonium - nuclear fuel

Plutonium - nuclear fuel

Plutonium is a chemical element with symbol Pu and atomic number 94 which belongs to the actinide series of elements. Plutonium has 16 isotopes, all radioactive. The element is a silvery metal and has 5 different crystal structures.

Chemically plutonium is a very active material. You can form compounds with all nonmetals except the noble gases. The metal dissolves in acidic and reacts with water, but only moderately in comparison with the acid.

While you can find traces in nature, all isotopes of plutonium are of artificial origin.
