The world is permeated with a wide variety of radiation.
Most of them are invisible to humans, some of them can perceive it.
Despite the fact that most of the radiation is not available to a person, their role in his life can not be overestimated.
human organs of perception are able to perceiveonly a small part of the penetrating space radiation. Infrared radiation is perceived as heat, and the visible range of the light spectrum rays - the light of a particular color. The presence of ultraviolet radiation a person can be identified by the appearance of sunburn, but just can not accept it.
What would not be in this world of radiation? The answer is simple: in the world there would be no life, and indeed it is unlikely to be able to appear. That energy of radiation is in the nature of the driving force. The bulk of energy, providing all the variety of life and take place in the world of physical processes, giving sun. That is its radiation heats the atmosphere and water, thereby moving air mass flow of the river, the formation of waves in the seas and oceans.
Oil, coal and gas is still a majorsources of energy for the human, could not come, do not be in the world of solar energy. For hundreds of millions of years it was used plant - otmiraya, they form thick layers of plant deposits, of which since shaped coal and oil. Without the solar radiation on earth it would be not only of plants, but generally a life.
Due to radiation it has the opportunitysee. The eye is able to perceive light photons in the range from red to purple, each color corresponds to a different wavelength of light. The world is perceived only because the eye picks up the reflected light waves from the object. It is enough to close his eyes, to deprive themselves of the opportunity to perceive the light radiation in order to understand what this good - to be able to see.
Man has long learned to use differenttypes of radiation. Once he was just basking in the sun or the fire, feeling the portable infrared heat. Later, along with the development of civilization and the development of science, the possibility of using radiation greatly enhanced. Man captured by electromagnetic radiation, so there was a radio and television, modern cellular communications. I learned to induce coherent radiation that led to the laser technology. X-ray radiation is widely used in medicine and industry, as an active person uses radioisotopes radiation - for example, to fight cancerous tumors.
You can make a well-founded conclusion that the role ofradiation in a person's life is incredibly high. Thanks to them, there was the Earth, and the man himself, they are widely used in many areas of life. Thus there is every reason to believe that not all types of radiation discovered and studied. It is possible that with their discovery and implementation, human life changed the most amazing way.</ P>
