Half Lives shines a light on the shocking history of the worlds toxic love affair with a deadly substance, radium. Unnerving, fascinating, informative and truly frightening. Hallie Rubenhold, author of The FiveThe story of this supposed cure-all in everyday 20th century life is fascinating and well told. Brian Maye, Irish Times Lucy Jane Santos presents the surprising history of radium in everyday life. Of all the radioactive elements discovered at the end of the 19th century, it was radium that became the focus of both public fascination and entrepreneurial zeal.Half Lives tells the fascinating, curious, sometimes macabre story of the element through its ascendance as a desirable item - a present for a queen, a prize in a treasure hunt, a glow-in- the-dark dance costume - to its role as a supposed cure-all in everyday 20th-century life, when medical practitioners and business people (reputable and otherwise) devised ingenious ways of commodifying the new wonder element, and enthusiastic customers welcomed their radioactive wares into their homes. Historian Lucy Jane Santos - herself the proud owner of a formidable collection of radium beauty treatments - delves into the stories of these products and details the gradual downfall and discredit of the radium industry through the eyes of the people who bought, sold and eventually came to fear the once-fetishized substance. She reveals a new history of radium, one in which the stories of those previously dismissed as quacks and fools are brought to life, as part of a unique examination of the interplay between science and popular culture.

"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."

Con el objetivo de servir de ayuda a los alumnos que cursan Física Aplicada y Fisicoquímica en las facultades, nace este libro. Los magníficos textos al uso son desproporcionados para lo que puede explicarse en tres creditos, que es la extension asignada a la Fisicoquimica dentro de la asignatura mencionada. Como consecuencia, el alumno se encuentra con libros de los que podra aprovechar una parte que, en el mejor de los casos, apenas llega al treinta por ciento. El tratar de aprender Fisicoquimica leyendo un texto unicamente, sin hacer problemas, es muy poco efectivo. Con esta intencion, se incluyen problemas resueltos incorporados al texto como Ejemplos y se añade una coleccion de problemas no resueltos al final de cada capitulo. La mayor parte de ellos son originales y han sido propuestos en examenes a lo largo de nuestra dilatada trayectoria universitaria.
