How did marie curie discover radiation
WebAs she measured the rays from different uranium compounds, she discovered that the more uranium atoms in a substance, the more intense the rays the substance gave off. Trying to see what was so special about uranium, she tested minerals containing other elements. She found that thorium compounds also gave off “Becquerel rays.” WebRadium has been isolated in the metallic state (M. Curie and A. Debierne, 1910). The method used consisted in distilling under very pure hydrogen the amalgam of radium formed by the electrolysis of a chloride solution using a mercury cathode. One decigram only of salt was treated and consequently considerable difficulties were involved.
