Chris Packham explains how Marie Curie’s discovery of polonium and radium changed atomic theory and how her study of radioactivity helped doctors use X-rays to save thousands of lives.

In 1895, Wilhelm Röntgen discovered X-rays while experimenting with cathode rays and crystals, leading to the realization ...

When Marie and Pierre Curie discovered the natural radioactive elements polonium and radium, they did something truly remarkable– they uncovered an entirely new property of matter. The Curies ...

Scientists have confirmed the existence of a unique phase of water called 'plastic ice VII,' which forms under extreme ...

Famous for her research on radioactivity, a technique to isolate the radioactive isotopes and the discovery of Polonium and Radium, Marie was the first person to be honored by two Nobel Prizes. Marie ...

Radium, polonium and radon may be names to make your hair stand on end, but are they actually useful for anything? And is our fear of them overbaked? Laurence Knight gets the chemistry rundown ...

Not only was the phenomenon itself discovered by Becquerel, but other landmark achievements in the field included the isolation of the radioactive elements polonium and radium by the Curies ...

Since the Curie-Joliots of Paris discovered artificial radioactivity ... Radium E is the seventh and last stage of radium disintegration before it turns into polonium. Its atomic weight is 210.

The Belgian pitchblende mines, whence the related radium, polonium and lead are refined, are at Katanga, Belgian Congo. Those mines have far outdistanced the Jackinov mines in Czechoslovakia where ...

Wickham and Degrais, have created a sensation at the Academy of Medicine by a report on their discovery of a method of removing birthmarks by the action of radium. Such marks have hitherto been ...

They discovered a new element that gave off rays of heat and light - they called this radium. They studied the light and heat it gave off and called this radioactivity. They were given the most ...
