Who discovered radioactive dating
The discovery of radioactivity took place over several years beginning with the discovery of x-rays in 1895 by Wilhelm Conrad Roentgen and continuing with such people as Henri Becquerel and the Curie family.
Contributions: Received the Noble Prize in physics for being the first to discover radioactivity as a phenomenon separate from that of x-rays and document the differences between the two.Henri Becquerel learned of Roentgen's discovery of x-rays through the fluorescence that some materials produce.Using a method similar to that of Roentgen, Becquerel surrounded several photographic plates with black paper and florescent salts.With the intention of further advancing the study of x-rays, Becquerel intended to place the concealed photographic paper in the sunlight and observe what transpired.Unfortunately, he had to delay his experiment because the skies over Paris were overcast.
