The term "radiation therapy" most often refers to external beam radiation therapy. Radiation, flow of atomic and subatomic particles and of waves, such as those that characterize heat rays, light rays, and X rays. • A major source of ionizing radiation is nuclear transformation. In 1900, the German physicist Max Planck (1858–1947) explained the ultraviolet catastrophe by proposing that the energy of electromagnetic waves is quantized rather than continuous. Radiation is the transmission or emission of energy in the form of particles or waves through space or through a material medium. Home. Technological applications based on the manipulations of light include lasers, holography, and fibre-optic telecommunications systems..
