Gamma rays were first discovered by Paul Villard, a French chemist and physicist, in 1900 while he was studying radiation emissions from radium. Later, in 1903, Ernest Rutherford recognized them as a distinct form of radiation differing from alpha and beta rays in their much greater penetrating power. This discovery marked the beginning of our understanding of gamma radiation as the most energetic form of electromagnetic radiation, leading to significant advancements in both medical treatments and our understanding of the universe, including the processes inside nuclear reactions and cosmic phenomena.
