Stray X-rays escaping from a laboratory or doctor's office and endangering the health of persons in adjoining rooms will have their teeth pulled by an invention of Maximilian Toch, Manhattan chemist. Metallic lead sheathing has been used in such rooms to keep the rays in, but this is costly and the heavy metal requires special strengthening of building walls. Toch's method is the use of a barium compound in the plaster or paint on the walls of the X-ray room, barium being impervious to the rays...

...details of the years 1897-1906 in which radium was discovered form a saga of heroism. Not long after her marriage in 1895, Marie Curie, became interested in the experiments of Henri Becquerel on the salts of the rare metal, uranium. He had found that they emitted certain penetrating rays. Marie Curie took up this work, found that another element, thorium, behaved similarly, and that certain complex minerals also showed radioactivity, which was not, however, proportionate to the quantities of uranium or thorium in them. Pierre Curie, whose main researches up to that time had been on the physics...
...killed in the prime of life, April 19, 1906, by a Paris truck ?one of the most irreparable and unnecessary losses ever suffered by science. Madame Curie struggled on with her two small daughters, and continued their great work until, in 1910, she isolated the mysterious white metal of radium itself. That her own achievements were as great as her husband's was attested by the Nobel Award in Chemistry (1911) to her alone, eight years after the Physics Prize had been given jointly to Becquerel, Pierre Curie and herself. The Sorbonne appointed her to the chair left vacant...
