About This Book
The text traces the scientific journey from early ideas about indivisible matter through experimental discoveries that revealed subatomic particles, radioactivity, and the nuclear structure of atoms. It explains how experiments with cathode rays and radioactive materials led to identification of electrons, protons, neutrons, and isotopes, and how binding energy in nuclei makes mass convertible to large amounts of energy. The booklet outlines fission theory, the development and testing of fission weapons, and prospects for controlled nuclear power and fusion. It surveys practical applications of isotopes and radioisotopes, describes the role of national atomic authorities, and discusses international cooperation and suggested further reading.
