Ionizing radiation

Ionizing radiation - is, in the general sense of the word, different types of physical fields and microparticles.If viewed from a narrow point of view, do not treat him ultraviolet radiation and visible light, which in some cases can be ionizing.Microwave radiation and ionizing radio bands are not, because their energy is not sufficient for the ionization of molecules and atoms.

In today's widespread ionizing radiation.It is, in fact, radiant energy, which is the interaction with the environment forms an electrical charges with different signs.It is used for peaceful purposes, such as for a variety of X-ray machines, accelerators.It is used in agriculture.

accidents at nuclear power plants, nuclear explosions, various nuclear transformations occur and acts do not feel and do not visible to the human touch of ionizing radiation.Nuclear radiation can be electromagnetic in nature or it can be a fast-moving stream of elementary particles - protons, alpha and beta particles, neutrons.In the interaction with different materials, they ionize molecules and atoms.The more power the dose of ionizing radiation, the ionization of the medium will be stronger, and the duration of exposure to radiation and radioactivity.

humans and animals ionizing radiation acts in a way that destroys the living cells.This can lead to varying degrees of diseases, and in some cases (high doses) in death.To understand and study its impact, it is necessary to take into account its main characteristics: ionizing and penetrating ability.

If we consider every detail separately ionizing radiation (alpha, beta, gamma, neutrons), it can be concluded that the Alpha is highly ionized and a weak penetrating power.In this case, fine clothes can protect people.The most dangerous thing - it's getting it with water, food and air in a living organism.In Beta - smaller ionization, but more penetrating.There is not enough clothes, you need to cover more serious.Neutron or gamma radiation has a high penetrating power, protection should be in the form of fallout shelters, reliable cellar or basement.

Consider ionizing radiation, its types and properties.The most diverse radioactive, they are formed in connection with the unauthorized radioactive decay of atomic nuclei of elements, changing their chemical and physical properties.Such elements are radioactive.They may be either natural (such as radium, thorium, uranium, etc.) and obtained by artificial means.

ionizing radiation.Types

Various different mass, energy and charge.Within each species has its differences - is less or more ionizing and penetrating ability, as well as other features.The intensity of this radiation is inversely proportional to the ratio of the square of the distance from the power source directly.When the distance is several times its intensity is reduced accordingly.For example, if the increase in distance was doubled, irradiation decreased four.

presence of radioactive elements may be in the liquid and solids as well as gases.Therefore, in addition to their specific properties, ionizing radiation has the same properties as these three physical states.That is, it can form pairs and aerosols quickly spread in the air, pollute the atmosphere surrounding the surface of the equipment, the skin of the workers and their clothes, to penetrate the respiratory system, digestive tract, and others.
