Basic about Radiation

Automatic translation: Just over 100 years ago, a series of discoveries related to the study natural, and later - artificial radioactivity, put the beginning of a new era in the history of mankind. In the middle of the century called ^Atomic^, there were two fateful events: the bombing of Hiroshima and Nagasaki and the launch of the world's first nuclear power plants in Obninsk, when the energy of destruction was transformed into the energy of creation. Since then, for more than half a century, the atomic energy serves the world by meeting ever-growing needs humanity in light, warmth. The development of the economy is unthinkable without it, improving the quality of life of people. Radioactive substances used in other areas of human activity - in medicine in the diagnosis and treatment of diseases, in technology. The realities of our days, unfortunately, are associated with the possibility of radiation accidents that may result in radioactive contamination territories of cities and rural areas. It cannot be ruled out and the possibility of using a ''dirty'' bomb, which terrorists use to frighten; its main damaging factor is fear. A fire peacefully warming a home can become destructive due to negligence or malice; nevertheless, people learned long ago not only handle flames, but also deal with fires. Humanity must get rid of the fear of radiation. From radiation you can and should defend yourself. And the best defense is defense based on knowledge.
