Even the fissile U-235 still has a half-life of 700 million years and only accounts for about 0.7% of naturally occurring uranium. Later that same year, the Curie’s discovered another radioactive element which they named radium. On April 20, 1902, Marie and Pierre Curie successfully isolate radioactive radium salts from the mineral pitchblende in their laboratory in Paris. Along the same lines, Marie Sklodowska Curie’s discovery of the element radium in 1898 at first seemed to lead the way to a variety of novel medical treatments, but as the properties of radioactive materials became better known, radium’s health benefits came to seem more limited. The Radiumscope, a toy sold as late as 1942, offered a glimpse of radium in … Marie Curie obtained radium from pitchblende, a material that contains uranium, after noticing that unrefined pitchblende was more radioactive than the uranium that was separated from it.She reasoned that pitchblende must contain at least one other radioactive element. In Toys and Nightlights. One ton of uranium ore contains only about 100 micrograms (0.0001 grams) of polonium. P. Curie proved that this property, later called radioactivity, is characteristic of the atom of uranium and is possessed also by thorium.

(Photo credit: NASA) A few days before the Christmas of 1898, Pierre Curie scrawled the word 'radium' in his notebook as … Radium was so named as it glowed in the dark. The discovery of polonium had been relatively easy; chemically it resembles the element bismuth, and polonium was the only bismuth-like substance in the ore. Radium, however, was more elusive; it is closely related chemically to barium, and pitchblende contains both elements. The day after Christmas 1898, a second paper came out, announcing the discovery of another new element: radium. In 1898, Pierre and Marie published a paper announcing the new element they discovered. Ultimately, her own discovery most likely led to her demise: in 1934, she died of aplastic anemia, a condition that was caused by prolonged exposure to radium and polonium.
