: In 1899, he demonstrated that some radioactive rays (beta particles) could be deflected by magnetic fields, proving they were charged particles rather than waves.

: This proved that radiation was an inherent property of certain atoms, a phenomenon later named "radioactivity" by his doctoral student, Marie Curie . Key Scientific Contributions antoine henri becquerel

: Inspired by the discovery of X-rays, Becquerel wanted to see if phosphorescent materials emitted X-rays after being exposed to sunlight. : In 1899, he demonstrated that some radioactive
