Book Description
Marie Sklodowska Curie was a Polish and naturalized-French scientist who remains today one of the most extraordinary figures in modern physics and chemistry. She was the first person to win two Nobel Prizes (in Physics and in Chemistry) and the first woman scientist to be awarded the Nobel Prize in Physics. After being denied a position at the University of Kraków, due to the common sexism in the academia of the time, she returned to Paris to work together with Pierre Curie. At the end of the 19th century, Henri Becquerel had discovered the new phenomenon of radio-activity (a term later coined by Marie Sklodowska Curie) in uranium salts. Sklodowska Curie built upon this study and made two fundamental discoveries in the field. First, she discovered that radio-activity is a property of certain elements (like uranium and thorium) of the periodic table, and it is not due to the chemical properties of compounds. Second, she discovered two new radio-active elements, polonium and radium. This book presents her address at Vassar College from 1921 and her Ph.D. thesis, defended in 1903 at the Faculty of Science of the Université de la Sorbonne in Paris. Her thesis, described by the examining committee as the best contribution to science ever presented, made Marie Sklodowska Curie the first woman to obtain a doctoral degree in the history of France. Newly translated from the French second edition, it represents a true masterpiece of science and describes in detail her efforts to understand the origin of radioactivity. To appreciate the beauty of her work one has to keep in mind that, at the time, the structure of the atom was largely unknown (the first attempt was made by J.J. Thomson in 1904). Due to high exposure to radiation, she died from aplastic anemia at the age of 66.

Book Description
Naturally occurring radionuclides are found throughout the earth's crust, and they form part of the natural background of radiation to which all humans are exposed. Many human activities-such as mining and milling of ores, extraction of petroleum products, use of groundwater for domestic purposes, and living in houses-alter the natural background of radiation either by moving naturally occurring radionuclides from inaccessible locations to locations where humans are present or by concentrating the radionuclides in the exposure environment. Such alterations of the natural environment can increase, sometimes substantially, radiation exposures of the public. Exposures of the public to naturally occurring radioactive materials (NORM) that result from human activities that alter the natural environment can be subjected to regulatory control, at least to some degree. The regulation of public exposures to such technologically enhanced naturally occurring radioactive materials (TENORM) by the US Environmental Protection Agency (EPA) and other regulatory and advisory organizations is the subject of this study by the National Research Council's Committee on the Evaluation of EPA Guidelines for Exposures to Naturally Occurring Radioactive Materials.

Book Description
"The object of the present work is the publication of researches which I have been carrying on for more than four years on radio-active bodies. I began these researches by a study of the phosphorescence of uranium, discovered by M. Becquerel. The results to which I was led by this work promised to afford so interesting a field that Pierre Curie put aside the work on which he was engaged, and joined me, our object being the extraction of new radio-active substances and the further study of their properties."

Marie Curie discovered radium and went on to lead the scientific community in studying the theory behind and the uses of radioactivity. She left a vast legacy to future scientists through her research, her teaching, and her contributions to the welfare of humankind. She was the first person to win two Nobel Prizes, yet upon her death in 1934, Albert Einstein was moved to say, "Marie Curie is, of all celebrated beings, the only one whom fame has not corrupted." She was a physicist, a wife and mother, and a groundbreaking professional woman. This biography is an inspirational and exciting story of scientific discovery and personal commitment. Oxford Portraits in Science is an on-going series of scientific biographies for young adults. Written by top scholars and writers, each biography examines the personality of its subject as well as the thought process leading to his or her discoveries. These illustrated biographies combine accessible technical information with compelling personal stories to portray the scientists whose work has shaped our understanding of the natural world.

Book Description
Marie Curie was long idealized as a selfless and dedicated scientist, not entirely of this world. But Quinn's Marie Curie is, on the contrary, a woman of passion — born in Warsaw under the repressive regime of the Russian czars, outspokenly committed to the cause of a free Poland, deeply in love with her husband Pierre but also, after his tragic death, capable of loving a second time and of standing up against the cruel, xenophobic attacks which resulted from that love. This biography gives a full and lucid account of Marie and Pierre Curie’s scientific discoveries, placing them within the revelatory discoveries of the age. At the same time, it provides a vivid account of Marie Curie’s practical genius: the X-Ray mobiles she created to save French soldiers' lives during World War I, as well as her remarkable ability to raise funds and create a laboratory that drew researchers to Paris from all over the world. It is a story which transforms Marie Curie from an bloodless icon into a woman of passion and courage. "Quinn's portrait of Curie is rich and captivating. Quinn strives to peel back... layers of myth and idealization that have grown up around the physicist... She succeeds beautifully. Quinn has written a worthy successor to her previous work, the award-winning biography of American psychiatrist Karen Horney." — Washington Post Book World (page 1) "A touching, three-dimensional portrait of the Polish-born scientist and two-time Nobel Prize winner." — Kirkus "I've read many biographies of Marie Curie and Susan Quinn's is magnificent. It's so complete and so evocative that I can't imagine anyone coming away from reading it without feeling they actually know Marie Curie." — Alan Alda "Quinn portrays a woman who was both independent and ambitious, in a society that was unprepared for either. The result is a fresh, powerful new biography of a very human Marie Curie... This is an exemplary work, rich in the details and connections that bring a person and her era to life. It is certain to be this generations' definitive biography of Marie Curie." — Science "Quinn breaks ground in her detailed description, drawn from newly available papers, of Marie's life after Pierre's accidental death in 1906. At first so grief-stricken she neglected her two daughters, Irene and Eve, Marie later had a love affair with French scientist Paul Langevin. Because Langevin was married, Marie was vilified by the French press and was almost denied the 1911 Nobel Prize for chemistry." —Publishers Weekly "Susan Quinn's excellent biography gives a lucid account of Curie's contribution to our understanding of 'things'... but Quinn also draws on new material to paint a more rounded and attractive picture of Curie the person... For Marie, the enchantment of her science never waned, and it is this enchantment which Quinn's biography communicates so well." — London Observer
