""Radioactive Substances"" is a scientific book written by Marie Curie and published in 1904. The book is a comprehensive study of the physical and chemical properties of radioactive substances, including uranium, thorium, and radium. It also explores the nature of radioactivity, the emission of particles and energy from radioactive substances, and the effects of radiation on living organisms. The book is divided into three sections: the first section provides an introduction to the properties of radioactive substances, the second section focuses on the measurement of radioactivity, and the third section explores the practical applications of radioactivity in medicine, industry, and research. Marie Curie, the author of the book, was a pioneering scientist who made significant contributions to the field of radioactivity. She was the first woman to receive a Nobel Prize in Physics in 1903, and later received a second Nobel Prize in Chemistry in 1911 for her work on radium and polonium. ""Radioactive Substances"" is a seminal work in the history of science and remains a valuable resource for anyone interested in the study of radioactivity and its applications.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
