We are constantly surrounded by a number of different emissions, which in one way or another have an impact on the body.Scientists differently expressed about the consequences of this phenomenon, although it is also worth noting the fact that manufacturers of household appliances and other electronics are constantly working to reduce the impact.
greatest danger caused by radiation - radiation, to some extent are not only dangerous, but also mysterious.It is credited with different properties to change the characteristics of the organism, for the most part negative.The impact of radiation on the human body continues to be studied.The reason is that various health problems, or a variety of disabilities is often credited with radioactive radiation.
main danger lies in the fact that it is invisible and there is no way, without special equipment.One can not feel that he is under exposure to the very long as the effects of radiation on the human body begins to manifest itself fully.
Features of human exposure
can be divided effect of radiation on the human body into two types:
- Somatic.
- genetic.
In the first case we are talking about the immediate impact of a solid, iethe effect of radiation on the human body manifests itself in immediate changes and deviations.However, the radiation in varying degrees, damage the genetic apparatus, which is manifested in subsequent generations.Some say that the second type of impact is much more dangerous, and it causes a general deterioration in the health of the nation and society.After each successive generation gets some genetic abnormalities, and they constantly accumulate like a snowball.
manifestation of somatic effects
At the beginning of the effect of radiation on the human manifests itself in the form of somatic effects.There are several basic types:
- radiation sickness.
- leukemia.
- variety of tumors.
- Local radiation injuries.
radiation acting on the cells of the human body, causing a variety of chemical and physical processes.The most dangerous in the case of beta radiation, since it has a strong penetrating properties.Alpha particles have low density and greatly disrupt the mucosa.As a result, cells lose their integrity, ionization, and it becomes the cause of the violation of their normal life.
Types of radiation sources in the environment
Most of the radiation a person receives in a natural way.Avoid this absolutely impossible.The sources should include the sun, various cosmic sources, etc., and on the surface of the earth and its crust is full of radioactive minerals.
impact of radiation on the human body comes in three basic reasons:
- inhalation of contaminated air.
- Eating contaminated food.
- effects of radiation on open wounds.
Infection through inhalation of air containing radioactive isotopes, the most dangerous, as a result of pulmonary ventilation, they quickly spread throughout the body.However, in any of these cases, these materials fall within a few minutes in human blood.If there was no exposure, the concentration of hazardous substances decreases after 15-20 days.While some types of isotopes live much longer.
In the first stage, the ionization cell, which is manifested in the form of radiation sickness.Further radiation provokes various chemical reactions involving proteins, various amino acids, water, etc.
All this leads to extremely negative changes in the body that depends on the duration and impact.
