What is radiation?

radiation is associated with the inevitable for many diseases that are difficult to treat.And this is partly true.The most terrible and deadly weapon called nuclear.Therefore, not without reason, consider radiation one of the biggest disasters on earth.What is radiation and what are its implications?Consider these questions in this article.

Radioactivity - a nucleus of some atoms, which differ instability.As a result of nuclear disintegration properties it occurs which is caused by ionizing radiation.This radiation is called radiation.It has a large power capacity.The impact of radiation on the human body is to change the composition of cells.

are several types of radiation, depending on the level of its impact on living organisms.

first type - is the alpha particles.Alpha decay exposed to radioactive elements: uranium, bismuth, thorium and others.Simply put, the isotopes decay of heavy elements.

What is the radioactive decay?This ejection of the nucleus of any particle.As a result, the formation of another chemical element table on the basis of the original element.Alpha decay - this is the core of the ejection of alpha particles.

second type - this is a beta particle.It is also one of the most common types of decay.He was exposed to almost all chemical elements of the table.Most often, there is negative beta decay.This ejection of the core beta-minus particle.The result is the formation of an element in the right of the entry table of the chemical, which has room for one more.

The third type includes gamma radiation.This is a more gentle radioactivity.

last two types - a neutrons and X-rays.With this kind of radiation we encounter in everyday life.It is very safe for the human body.

Therefore, apart from the fact that such radiation, it is necessary to consider the level of radiation and the harm caused to living organisms.

Radioactive particles have a huge energy capacity.They penetrate into the body and face with its molecules and atoms.As a result of this process, their destruction.The peculiarity of the human body is that it largely consists of water.Therefore, the effects of radioactive particles are exposed to molecules of this particular substance.As a result, there are very harmful to the human body connection.They become part of the chemical processes occurring in living organisms.All this leads to the destruction and elimination of cells.

Knowing that such radiation, one must also know what kind of damage it causes to the body.

effects of radiation on human is divided into three main categories.

main harm is caused genetic background.That is, as a result of infection occurs alteration and destruction of germ cells and their structures.This is reflected in the offspring.A lot of born children with disabilities and deformities.This is mainly in areas that are prone to radiation contamination, that is located next to the nuclear power plants and other enterprises at this level.

second type of diseases caused by radiation is hereditary disease at the genetic level that appear after a while.

third kind - is immune diseases.The body under the influence of radiation becomes susceptible to viruses and diseases.That is, reduced immunity.

salvation is the distance from the radiation.The permissible level of radiation for humans is 20 micro-roentgen.In this case, it has no effect on the human body.

Knowing that such radiation can be to a certain extent to protect themselves from its effects.
