Radiation

Radiation is an invisible pollutant that can be highly dangerous. Nuclear radiation comes from radioactive substances, including waste from nuclear weapons testing and from nuclear power plants. Small amounts of electromagnetic radiation are produced by a variety of electronic devices including computers, lasers, microwave ovens, TV sets, and X-ray machines.

Scientists have not determined exactly what effects small amounts of radiation influence people. But exposure to large amounts can cause cancer and harmful changes in reproductive cells.

International agreements ban most testing of nuclear weapons in the atmosphere. Such regulations have helped to eliminate the major sources of radiation. However, the amount of radioactive waste is constantly increasing. Scientists are studying the ways to eliminate these wastes safely and permanently.

A. S. Pushkin is the greatest Russian poet. But I hope no one is challenging the view that he occupies an outstanding place in Russian literature and culture.

Every summer in June, thousands of people visit the Pskov land. They come here to the village of Mikhailovskoye to the wonderful festival of poetry, to see the places where he lived and worked.

Pushkin is always alive for us, he is the man we all know and love, the greatest of poets. Generations come and go, but Pushkin still remains. We are all grateful to Pushkin for each line of his works. Pushkin is not only a great poet for us. He is the perfect man combining brilliant talent with civil courage. His name is associated with our love for the Motherland, and the best in our life.

Hundreds of new concepts, hundreds of new words have appeared in the language in the years that have passed since his death, but not a single word of his poetry has become obsolete. Everything written by Pushkin continues to live. It has not become something of the past, it does not need any corrections and hardly needs commentary. His feelings and his views still correspond to our own feelings and views.

We admire the great world of Pushkin's poetry as a whole, each of us finding some special lines for ourselves, lines showing his sympathy and respect for his people. The reader cannot imagine his inner world without him.
