I'm pretty sure it was Marie currie
discovered polonium discovered the existence of radium found how to isolate the radium metal discovered that thorium was a radioactive element discovered that uranium rays give conductivity to the air surrounding them
The word "radium" comes from the Latin word "radius," meaning ray, due to its highly radioactive nature that emits rays. It was discovered by Marie and Pierre Curie in 1898.
Radium was discovered by Marie Curie and her husband Pierre Curie in 1898. They isolated the element while studying uranium rays and conducted extensive research on radioactivity. Albert Einstein, Isaac Newton, and Louis Pasteur made significant contributions to their respective fields, but they were not involved in the discovery of radium.
She discovered radioactivity and the elements Radium and Polonium!
Energy in the form of rays
first work with x razs had nikola tesla but he wasn'z verz interested, after that i think Rentgen did.
Any link exist between X-rays and polonium&radium.
The name radium comes from a Latin word radius, which means ray. It was named this because the chemists found that photographic effects were similar at light rays.
Radium was used in the past for the radiotherapy of some cancers, because radium is radioactive and emit gamma rays (also alpha and beta particles).
Paul Villard discovered gamma rays in 1900 while studying radiation from radium. He observed a new type of penetrating radiation that was more powerful than alpha and beta rays, and he named it "gamma rays" after the third letter of the Greek alphabet.
Radium is a warm as a consequence of energy release by nuclear reactions - radioactive decay with the emission of alpha, beta and gamma rays.
Johann Wilhelm Ritter discovered ultraviolet rays
