In 1895, Wilhelm Röntgen discovered X-rays while experimenting ... Rutherford categorized radioactive emissions into alpha, beta, and gamma rays, leading to the understanding of radioactive ...

The discovery of radioactivity ... underwent this transmutation process. Alpha radiation, can be blocked easily with nothing more than a sheet of paper. Beta radiation, requires something heftier ...

The use of other radiations (except X-rays), for example, alpha-and beta-rays, recoil atoms and accelerated ions for similar purposes does not seem to have been described. The rapidly increasing ...

Such unstable atoms are called “radioactive atoms”. When radioactive atoms decay, they release energy in the form of ionizing radiation (for example alpha particles, beta particles, gamma rays or ...

Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900, while studying radiation emitted from radium. Alpha and beta "rays" had already been separated and named by the ...
