Henri Becquerel's Groundbreaking Radioactive Discovery

Henri Becquerel, a French physicist, discovered the phenomenon of radioactive decay when studying fluorescent materials. Using a uranium salt, he found that it emitted rays that could expose photographic plates, leading to a deeper understanding of atomic behavior. This unexpected discovery marked the beginning of radioactivity research, inspiring subsequent studies by scientists such as Marie Curie and Ernest Rutherford, who focused on understanding radiation's properties and effects on matter.
