Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later.

2025年1月30日 · Radium was discovered (1898) by Pierre Curie, Marie Curie, and an assistant, G. Bémont, after Marie Curie observed that the radioactivity of pitchblende was four or five times greater than that of the uranium it contained and was not fully explained on the basis of radioactive polonium, which she

1996年12月1日 · On November 8, 1895, Wilhelm Conrad Röntgen at the University of Würzburg, discovered a new kind of radiation which he called X-rays. It could in time be identified as the short-wave, high frequency counterpart of Hertz’s waves.

In the year 1896 H. Becquerel discovered that uranium emits spontaneously a radiation that produces an impression on a photographic plate through a sheet of black paper, and ionises the air. Mme. P. Curie proved that this property, later called radioactivity, is characteristic of the atom of uranium and is possessed also by thorium.

On December 10, 1903, Marie and Pierre Curie are awarded a Nobel Prize in Physics for their groundbreaking investigations of radioactivity, sharing the prize with French scientist A. Henri...

On December 20th, 1898, Pierre Curie scrawled the word 'radium' in his notebook as the name for a new element he and his wife Marie had discovered in their laboratory in Paris.

Who Discovered Radium: Renowned scientists Marie Curie and Pierre Curie were the discoverers [1] When, Where, and How was it Discovered. Marie Curie had observed that pitchblende (uranium oxide) was more radioactive even after extracting uranium from it.

The article recounts Marie and Pierre Curie’s discovery of radium and discusses its properties, production, and applications. The article mentions only in passing that the radioactivity emitted by radium causes “a selective destruction of certain cells and can have very dangerous consequences”—a property sadly demonstrated in later ...

2008年2月21日 · It was soon discovered that radium shared properties with X-rays. Both were capable of burning skin and became popular for use in burning off lesions, warts, or cancers as early as 1903. Soon afterward, radium began to be marketed as …

From the initial discovery of radium in 1898 by the Curies to its widespread use in the Golden Age, and finally to its rapid decline, the radium industry has a remarkable history worth examining more closely.
