RADIOACTIVITY AND CURRENT TENDENCIES.The first days of radioactivity, the discoveries of X-rays, radioactivity, of αand βparticles and γradiation, of new radioactive elements, of artificial radioactivity, the neutron and positron and nuclear fission are reviewed as well as several adverse historical marks, such as the Manhattan project and some nuclear and radiological accidents.Nuclear energy generation in Brazil and the world, as an alternative to minimize environmental problems, is discussed, as are the medicinal, industrial and food applications of ionizing radiation.The text leads the reader to reflect on the subject and to consider its various aspects with scientific and technological maturity.
